Es wird heute weltweit versucht, Konzepte für vielfältige taktile kartographische Medien zu entwickeln, die vorrangig der allgemeinen Orientierung und Mobilität, aber auch verstärkt dem Wissenserwerb, z.B. im Geographieunterricht an Schulen für Blinde und Sehbehinderte, dienen sollen. Diese Konzepte müssen von denen der "visuellen Kartographie"1 zwangsläufig mehr oder weniger abweichen und auf weitgehend anderen Methoden, Regeln und Techniken beruhen. Wesentliche und durch die Praxis verifizierte Erkenntnisse der visuellen Kartographie sind der taktilen Kartographie zugänglich zu machen bzw. in/an diese zu adaptieren. Trotzdem dürfen grundlegende Theorien und Erfahrungen der Kartengestaltung und Kartennutzung für Sehende nicht völlig negiert werden.

Darbe yra siekiama išanalizuoti trimačio kartografinio vaizdo (žemėlapio) informatyvumo galimybes autoriaus sukurtų trimačių žemėlapių (modelių) pagrindu. Darbe apžvelgiami trimačio kartografinio vaizdo kūrimo metodai ir priemonės. Svarbų indelį trimačių kartografinių kūrinių sudaryme šiandien vaidina atskira grafinio dizaino kryptis – infografika. Tačiau trimatį kartografavimą palaikančių kompiuterinių programų nėra daug, pagrindinės iš jų leidžiančios sudarinėti erdvinius modelius yra ArcGIS ir AutoCAD. ArcGIS grafinio trimačio vizualizavimo ir Google SketchUp programinės įrangos pagrindu sukurti 4 trimačiai įvairių teminių sričių žemėlapiai. Informatyvumo nustatymo tikslui pasiekti yra vykdomas trimačių kartografinių ženklų informatyvumo, informacijos talpumo (kartografuojamų rodiklių kiekio atžvilgiu) bei panaudojimo tyrimas. Taip pat atliekama kartografijos profesionalų bei teminių sričių specialistų apklausa. Rezultatuose išryškėja pradinių kartografuojamų duomenų analizės svarba. Tinkamai parinkus kartografinį metodą leidžiantį atskleisti trečios dimensijos papildomas galimybes trimatis žemėlapis tampa informatyvesnis lyginant su įprastu planiniu kartografiniu vaizdu. Santykinių – hipotetinių paviršių žemėlapiai, kuriuose naudojami struktūriniai ženklai tinkamiausi socialinių rodiklių, o kombinuojant su tolydžiu paviršiumi – ir fiziniams reiškiniams kartografuoti. / The author is seeking to analize three-dimensional cartographical view informative opportunities created by the author 3D maps (models) basis. The paper gives an overview of 3D cartographic display methods and instruments. Important role in nowadays 3D mapping plays a separate graphic design trend – infographics. However 3D mapping computer programs are not many, the main ones allowing a spatial model are ArcGIS and AutoCAD. Basis of 3D graphics and imaging software ArcGIS together with Google SketchUp were created 4 different 3D thematic maps. Informative purpose is atchieved by research of 3D cartographic signs informative-capacity and uses potential. Also were done a poll of mapping professionals and thematic cartography specialists. Initial results revealed the importance of mapping data analysis. Properly selected mapping method allows to reveal additional opportunities of third dimension, in this way the map becomes more informative comparing it with two-dimensional map. Relative – hyphotethical surfaces maps in which are used structural cartographic signs is most appropriate for mapping of social indicators. And in the combination with continual surface (terrain model) – is appropriate for mapping of natural phenomena.

Cultural Aspects of Cartographic Creation: Use of Mental Maps in Cross-cultural Research Abstract: Diploma thesis deals with study of interdisciplinary issue of cultural aspects of cartographic creation. The first part of the work consists of theoretical introduction dealing with the map con- tent, map stylistics and map language, in which maps show the greatest cultural differences. The map figures here in a role of the image of reality and visual manifestation of culture. The analogy between a map and a classical language (linguistic anthropology) and the analogy between early maps and primitive cultures' maps are described. Beside the language, as determinants of the human spatial perception and other categories related to the map creation could be mentioned the environment, the experiences and the society, in which man lives. Several examples of so- called cultural map styles, especially from Australia and Oceania, are introduced as well. In the methodical part of the work in connection with cultural-anthropological research a method of cognitive maps, respectively mental maps of map users and map makers is discussed in detail. Just these maps are suitable to explore the cultural particularities of cartographic creation. The application part of the work presents the results of field research of mental...

Esta pesquisa trabalha com dois instrumentos importantes que representam o espaço geográfico, bem como, permitem perceber, conhecer, apreender e atuar sobre a realidade: os mapas e a modelização gráfica. O mapa como uma abstração da realidade espacial, que é modelizado e codificado com o propósito de ser apreendido. Mais que representar fenômenos espaciais, o mapa espacializa os fenômenos que representa, sejam eles espaciais ou não, materiais ou ideais. Todo mapa é fruto de transformações cartográficas espaciais. Transformação no sentido de que vai além da forma original que deveria representar, dando outra forma ao espaço geográfico analisado. Cartográfica, porque o objeto que é transformado é o mapa. Espacial, pois se refere às localizações, direções, distâncias e áreas. A modelização gráfica, por sua vez, é apoiada nos elementos estruturantes primordiais do espaço geográfico: os coremas [chorème]. Sob forma de figuras geométricas simples, os coremas escrituram modelos geográficos e estão estreitamente relacionados e próximos da cartografia, mas não se confundem. A modelização gráfica é geográfica, pois se refere às formas espaciais produzidas na apropriação do espaço pela sociedade. Mapas e modelização gráfica têm a função primordial de comunicar e de serem instrumentos de análise do espaço geográfico. Espaço geográfico compreendido aqui como dimensão da sociedade. Dimensão estabelecida pelo conjunto de relações sociais que se dão simultaneamente e mediadas pela(s) distância(s) que aproximam ou afastam realidade(s) diferentes ou iguais. Para dimensionar esta sociedade usando o mapa e a modelização gráfica, o recorte espacial foi a metrópole de São Paulo. Metrópole como lugar de concentração humana, de equipamentos culturais, sociais, de densidades e diversidades de um modo de vida típico de nosso mundo atual o urbano. Espaço representado em mapas e modelos coremáticos por meio de uma característica fundamental que evidencia seu caráter urbano: a densidade. Densidade expressa em mapa dasimétrico literalmente métrica da densidade evidenciando particularmente a densidade de população da metrópole e os mapas em anamorfose e cartogramas em anamorfose, que alterando o fundo de mapa tradicional, criam imagens de densidades. Estes mapas revelam estruturas e organizações que ajudam a compor uma síntese gráfica final da metrópole de São Paulo. / This research discuss two important ways to represent geographical space. Those representation techniques allow us to notice, know, apprehend and face reality: they are maps and graphic modelization. Map as an abstraction of spatial reality modelized and codified to be apprehended. More than represent spatial phenomena, the map turn visible the element that represent. The spatial distribution element might be spatial or not and might be material and ideal or not. Every map results from a spatial cartographic transformation. Transformation considered in a sense that goes beyond the original form that should be represented, giving another form to the analyzed geographical space. Cartographic, since the map is the object to be transformed. Spatial, since it refers to locations, directions, distances and areas. Graphic modelization, is based in the components that express geographic space: the choremes [chorème]. The choremes describe geographical models in graphical forms and are deeply related to cartography, but are not the same. Graphic modelization is geographical, because it refers to the social appropriation of space. Both, maps and graphic modelization aim to analyze and present the geographical space. To analyze the society spatial dimension through graphic modelization, the São Paulo Metropolitan Area was defined. Metropolis characterized by the concentration of people, cultural equipment, densities and diversities of urban life. Space that is represented in maps and with chorematic models that make evident their urban character: density. Density presented in dasymetric maps showing the metropolis population density and the cartogram. Those cartograms presenting the transformed map background generates an image of the densities. Those maps present structure and organization that contribute in the comprehension of the Sao Paulo Metropolis.

Os produtos cartográficos gerados pelo processo de Aerolevantamento são uma importante ferramenta de análise e tomada de decisões na engenharia moderna. Por outro lado a crescente demanda de projetos está levando pesquisadores a buscarem meios mais rápidos, econômicos e eficientes para obter bons produtos. Dessa maneira, vem surgindo novos equipamentos e produtos nessa área. Paralelamente, com o advento do posicionamento por satélite é possível um maior controle da qualidade cartográfica e a verificação da eficácia desses novos produtos. O presente estudo analisa diferentes tecnologias associadas ao uso da câmara digital não métrica de pequeno formato, como a HASSELBLAD H4D-31, com a utilização do Posicionamento por Ponto Preciso associado a um sistema inercial com e sem a utilização de uma base de referência (voo não apoiado), para a elaboração de ortofotos e cartas. Com relação à precisão geométrica e atendimento do padrão brasileiro de qualidade foram testadas comparativamente essas e outras alternativas, contando com dados da RBMC e apoio suplementar de campo. O produto resultante foi analisado também quanto à eficácia no que se diz respeito à boa qualidade da imagem com a identificação dos objetos em campo para utilização em projetos de engenharia. Ao final pode-se dizer que o produto foi validado, quanto à qualidade informativa e quanto à precisão necessária, atingindo o PEC classe A, para a escala 1:2.000. Ou seja, esse produto é uma alternativa viável tecnicamente e de menor custo, para aplicações como as apresentadas no presente trabalho. / The cartographic products generated by Aerial Survey process is an important tool for analysis and decision in modern engineering. On the other way the growing demand for projects is leading researchers to seek ways more faster, economical and efficient to get good products. In this way, are emerging new equipments and products in this area. At the same time, with the advent of satellite positioning it is possible greater control of cartographic quality and checking the effectiveness of these new products. This study analyzes different technologies associated with the use of the digital camera not metric of small-format, as the Hasselblad H4D-31, using the Positioning Precise Point associated with an inertial system without the use of a reference base (flight not supported ), for the development of orthophotos and maps. Regarding the geometric precision and care of the Brazilian standard of quality we were tested compared these and other alternatives, with data RBMC and additional support field. The resulting product was analyzed as well as the effectiveness as it relates to the quality of the image with the identification of field objects for use in engineering projects. At the end it can be said that the product was validated information as to quality and as to the necessary precision, reaching the PEC class A, to 1: 2000. That is, this product is a technically feasible and low-cost alternative for applications such as those presented in this work.

Através do desenvolvimento de novas tecnologias associadas ao geoprocessamento têm sido possível dimensionar problemas ambientais de forma muito mais precisa. O Google Earth disponibiliza gratuitamente imagens de satélites para as pessoas que têm acesso à internet. Para muitos locais essas imagens são de alta resolução e passíveis de serem utilizadas em muitas atividades de planejamento urbano e ambiental. Assim o principal objetivo desse trabalho foi por meio da utilização de imagens de alta resolução disponibilizadas gratuitamente pelo Google Earth e com o auxílio de um Sistema de Informação Geográfica (SIG), analisar a viabilidade de utilização das mesmas na definição das Áreas de Proteção Permanente (APPs) do Município de São Leopoldo/RS. Ainda como objetivos secundários são apresentados um método de estruturação de mosaicos advindos de cenas capturadas no Google Earth, verificação do Padrão de Exatidão Cartográfico (PEC) do mosaico e a proposta de um Sistema de Informação Geográfica (SIG) de baixo custo com a finalidade de auxiliar o gerenciamento ambiental de municípios de pequeno e médio porte. Como resultados obtidos através de testes estatísticos aplicados para analisar a qualidade da imagem georreferenciada e de acordo com a classificação do Decreto Lei 89817 ? Padrão de Exatidão Cartográfico concluiu-se que a imagem do Google Earth elaborada através de cenas capturadas a 5900 metros de altitude pode ser enquadrada em uma classe B e escala 1/15.000. Toda essa base cartográfica serviu como referência para geração das APPs, tais como: ao redor de nascentes, ao longo de cursos d´água, áreas úmidas e matas nativas, perfazendo as seguintes percentagens de ocupação territorial: 9,90%, 11,11%, 13% e 17%, respectivamente. Em termos de conclusões a pesquisa mostrou que imagens de satélites de alta resolução do Google Earth (associada a uma rede de pontos GPS) podem ser utilizadas de forma eficiente no aspecto de uma localização e quantificação mais precisa das APPs. Os produtos gerados por este estudo associados com a planta cadastral do município passam a desempenhar ferramentas importantes e de baixo custo para um planejamento integrado das diversas atividades desenvolvidas nas secretarias do município. / Nowadays our society experience a change of paradigm seeking for sustainability. Through the development of new technologies associated with GIS have been possible to measure environmental problems much more precise. Google Earth provides satellite images for free for those with internet access. In many places these images are high resolution and capable of being used in many activities of urban and environmental planning. In this manner, the main objective of this work was through the use of high-resolution images available for free at Google Earth and using a Geographic Information System (GIS) to examine the feasibility of using the same definition of Areas of Permanent Protection (APPs) of the municipal district of São Leopoldo / RS. Although secondary objectives are presented as a method of structuring the resulting mosaic of scenes captured on Google Earth, check the Cartographic Accuracy Standard (PEC) of the mosaic and the proposal of a Geographic Information System (GIS) for low cost in order to help the environmental management of cities, small and medium businesses. As results from statistical tests applied to analyze the image quality and georeferenced according to the classification of Decree Law 89817 - Cartographic Accuracy Standard concluded that the image of Google Earth developed through scenes captured the 5900 meters in altitude may be framed in a class B and scale 1/15.000. All this served as a base map reference for generation of APPs, such as around fountainheads, along the water courses, wetlands and native forests, for the following percentages of territorial occupation: 9.90%, 11.11 %, 13% and 17% respectively. In terms of the research findings showed that the satellite images with high resolution of Google Earth (associated with a network of GPS points) can be used efficiently in the appearance of a more precise localization and quantification of APPs. The products generated by this study associated with the cadastral plan of the city will appear as a important toll with low cost for an integrated planning of activities in various departments of the municipal district.

It is considered that the Cartography takes great relevance in geographical studies, since it allows to analyze phenomena and objects through its spatiality. Among the several concepts of Cartography stands out the cartographic scale, understood as the similarity ratio between the area in the real and its representation, in other words, it is a relation of quantifiable proportion. However, the notion of proportionality is built, first, in non-quantifiable terms, from the relations of first and second order and the establishment of perceptual measures. Therefore, understanding the cartographic scale can be better carried from the work with the notion of non-quantifiable proportion present in the student living space. Assuming that the visual impairment limits the apprehension and comprehension from the space, it becomes important think about on the construction of the notion of proportion and the concept cartographic scale with VIs students, since such knowledge can enable other learning in relation to Geography and contribute to the development of skills orientation and mobility of these students. In this context, it was defined as objective of this research assess the contribution of tactile models to understand the notion of proportionality and cartographic scale by the students with visual impairment. Therefore, was adopted as methodology, the method of participatory research, establishing as search field the Centro Brasileiro de Reabilitação e Apoio ao Deficiente Visual (CEBRAV). In this institution were made steps monitoring/observation of subjects of the research; materials test; elaboration, manufacture and evaluation of tactile models; planning and development of didactic sequence; evaluation and analysis of the proposal. It is noteworthy that the tactile models, built from the theoretical-methodological foundations of the Tactile Cartography, allowed the construction of the notion of proportionality non-quantifiable and some aspects of the concept of cartographic scale, enabling moreover, show alternative solutions to the understanding of this concept, in quantifiable terms. / A Geografia Escolar, assim como a escola em geral, tem a responsabilidade de viabilizar a formação cidadã de seus alunos, os quais, a partir de posturas críticas e autônomas podem transformar suas realidades sociais. Considera-se que a Cartografia assume grande relevância nos estudos geográficos, uma vez que possibilita analisar fenômenos e objetos através de suas espacialidades. Dentre os diversos conceitos da Cartografia destaca-se o de escala cartográfica, entendido como a razão de semelhança entre a área no real e sua representação, ou seja, trata-se de uma relação de proporção quantificável. No entanto, a noção de proporcionalidade é construída, primeiramente, em termos não quantificáveis, a partir das relações de primeira e segunda ordem e do estabelecimento de medidas perceptivas. Portanto, a compreensão da escala cartográfica pode ser melhor efetivada a partir do trabalho com a noção de proporção não quantificável existente no espaço de vivência do aluno. Partindo do pressuposto de que a deficiência visual limita a apreensão e compreensão espaciais, torna-se relevante refletir sobre a construção da noção de proporção e do conceito de escala cartográfica com alunos DVs, uma vez que, tais conhecimentos viabilizam outras aprendizagens em relação à Geografia e contribuem com o desenvolvimento das habilidades de orientação e mobilidade destes sujeitos. Neste contexto, definiu-se como objetivo dessa pesquisa avaliar a contribuição das maquetes táteis à compreensão da noção de proporcionalidade e escala cartográfica por alunos com deficiência visual. Para tanto, adotouse como metodologia a modalidade de Pesquisa Participante, estabelecendo como campo de pesquisa o Centro Brasileiro de Reabilitação e Apoio ao Deficiente Visual (CEBRAV). Nessa instituição foram realizadas as etapas de acompanhamento/observação dos sujeitos da pesquisa; avaliação dos materiais; elaboração, confecção e avaliação das maquetes táteis; planejamento e desenvolvimento da sequência didática; avaliação e análise da proposta. Ressalta-se que as maquetes táteis, construídas a partir dos fundamentos teóricometodológicos da Cartografia Tátil, viabilizaram a construção da noção de proporcionalidade não quantificável e de alguns aspectos do conceito de escala cartográfica, possibilitando ainda, apontar alternativas para a compreensão desse conceito, em termos quantificáveis.

Nesta dissertação discorremos sobre o processo de aprendizagem da Geografia. A construção dessa pesquisa se deu a partir da elaboração de atividades organizadas em Sequência Didática, a qual abordava o lugar de vivência dos alunos, apreendido como contexto para o ensino das habilidades cartográficas e dos conceitos geográficos como urbanização, densidade demográfica e infraestrutura urbana. O objetivo desse trabalho foi a proposição de Indicadores da Alfabetização Científica para a Educação Geográfica, elaborando um sistema de avaliação do processo de ensino e de aprendizagem em Geografia. Para tanto, realizamos aproximações teóricas entre Pensamento Espacial, Alfabetização Cartográfica, Raciocínio Geográfico e Alfabetização Científica. O cerne do diálogo entre essas propostas está na preocupação em definir os conceitos e as habilidades que devem ser ensinadas em Geografia. Foi a partir dessa construção que elaboramos os indicadores e os testamos nas atividades da Sequência Didática. A metodologia em que nos baseamos foi a investigação qualitativa e interpretativa, pois, consideramos a ação dos alunos sobre o próprio meio e valorizamos as relações deles com o entorno escolar. Trazer o Lugar de vivência como uma abordagem conceitual e científica para a sala de aula foi uma forma de movimentar o raciocínio dos alunos a respeito das interpretações deles sobre o Lugar onde moram, as características das moradias, as infraestruturas e os serviços urbanos que os cercam. Portanto, a abordagem desenvolvida visou promover a aprendizagem significativa, valorizando de fato a compreensão dos fenômenos e a apreensão das habilidades e das teorias geográficas. Os dados gerados nos possibilitaram verificar os efeitos da pesquisa-ação, avaliar os resultados sobre a aprendizagem dos educandos e realizar reflexões sobre as atividades elaboradas. Essa análise foi estabelecida de acordo com os Indicadores para a Alfabetização Científica na Educação Geográfica (ACEG), possibilitando refletir sobre essa forma de averiguação e considerar a viabilidade do processo de ensinoaprendizagem a partir das teorias de ensino alicerçadas na Alfabetização Científica e Cartográfica e no Pensamento Espacial sob a perspectiva didática do Lugar como contexto. / In this dissertation thesis we discuss the process of learning Geography. The construction of this research was based on activities elaboration organized in Didactic Sequence, which approached the students\' living place, understood as context for the teaching of cartographic skills and geographic concepts such as urbanization, demographic density and urban infrastructure. The aim of this work was the proposal of Scientific Literacy Indicators for Geographical Education, elaborating an evaluation system of teaching and learning process in Geography. For that, we perform theoretical approaches between Spatial Thinking, Cartographic Literacy, Geographical Reasoning and Scientific Literacy. The heart of the dialogue between these proposals is the concern to define the concepts and skills that must be taught in Geography. It was from this construction that we elaborated the indicators and tested them on the activities of the Didactic Sequence. The methodology we used was the qualitative and interpretative research, therefore we consider the students\' action on the environment and enhance their relationships with the around school. Bringing the living Place as a conceptual and scientific approach to the classroom was a way of moving students\' reasoning about their interpretations of the Place where they live, the characteristics of the dwelling, the infrastructure and the urban services that surround them. Therefore, the approach developed was aimed at promoting meaningful learning, valuing the understanding of phenomena and the apprehension of skills and geographical theories. The data generated allowed us to verify the effects of the action-research, to evaluate the results about the students\' apprenticeship and to make reflections on the activities elaborated. This analysis was established according to the Indicators of Scientific Literacy for Geographic Education, enabling to ponder on this form of inquiry and to consider the viability of the teaching-learning process from teaching theories based on Scientific and Cartographic Literacy and Spatial Thinking, out of the didactic perspective of the Place as context.

Planning maps are not only, as is often silently assumed by planners, neutral technical tools to assist them in their design and analytical tasks or to communicate their findings to others. In complex multi-stakeholder planning processes maps are also inherently coloured representations of knowledge, the outcomes a specific way of learning resulting from the activity of mapping itself, and discursive means through which norms and interests are promoted as objective truths. This thesis research explored how members of a local stakeholder group representing farm business made sense out of, and judged the data quality of planning maps in a combined highway planning and environmental impact study in southern Ontario, executed by the province’s Ministry of Transportation. More specifically it was concerned with how participants evaluated the cartographic representation issues of interest to them in the context of a mayor decision in the transportation study: the location of the highway route, in which both its existing route and new route sections through rural lands were options. The research instruments were a map review workshop and a questionnaire. This research was theoretically underpinned by a framework that integrates three fields of knowledge: cartographic theory, planning theory, and theory on knowledge and sensemaking. The framework served as a sensitizing concept for the analysis and interpretation of the observations obtained from research participants. All three fields were explored with an emphasis on social constructivist understandings which facilitated the understanding of situations characterized by complexity and ambiguity where certain and objective knowledge becomes impossible and where the perspectives and interests of multiple stakeholders come to the foreground. The spatial data on the study cartography in general was judged as correct. The big exception was the data on water-related phenomena. Here participants, although they were familiar with the area, had access to the reviewed cartography for more than two years, and were well aware of the importance of water-related issues in the decision-making process, only during the workshop became aware that the data, recently released by an official data source, were strongly outdated. The findings confirmed the usefulness for planning processes of the simple review procedure followed in the workshop. The process of sensemaking by participants focussed strongly on two areas. First, the central issue of the group: the recognition of agriculture as strong and relevant business deserving recognition equal to urban businesses. Second, on an issue that was not part of the goals of the study, the identification of needs for compensation, not only for loss of assets, but also for ongoing increases of operational costs. Participants, in contrast to the study’s thematically organized overlay analysis which resulted in a fragmented determination of impacts based on readily available public information, emphasized the need to use the farm (business) as a functional whole against which to measure impacts, considering its overall operation and viability. In the workshop it became clear that determining impacts on a complex entity like a farm is equally complex, and hard to map in a comprehensive way. Using maps not for a comprehensive analysis but for learning by illustration or example, however, offers opportunities in these cases. In practice this would require a review of what is considered as legitimate knowledge in formal decision-making. Participants attitudes towards (the representation of) nature showed to widely divergent, and attachment to place was virtually not touched upon. The emphasis on agribusiness seemed to stem not only from material interests, but was also strongly related to identity. Participants judged that the study cartography reflected a strong urban bias. They found that agriculture was underrepresented compared to urban economic and ecological interests and sometimes also misrepresented. Numerous suggestions were made to include new layers of data in the cartography, and to visually emphasize already included data related to agriculture. Although some information was found as redundant, is was above all the lack of more detailed information on agriculture and agribusiness that participants emphasized as issues they would like to see corrected. Whereas some data on some issues where emphasized as missing altogether, in other cases, notably in drainage, participants emphasized missing complementary perspectives. Information suggested by participants to be included mostly served to emphasize the importance of the agricultural sector as a whole and to spare it from impacts, but would create both technical and political difficulties if it were to be used for the comparison between different route options through rural lands. Different types of metaphors played an important role in the sensemaking process by the participants. Some participants followed more rational approaches to sensemaking that emphasized the correctness and information content of the data, while others seemed to be stronger ware of the strategic-discursive role of the maps. Many participants judged the study cartography as little explicit and highly ambiguous in many aspects, an observation for which a plausible explanation is the MTO’s needs to make decisions not only based on technical evaluations, but also taking into account strong informal political forces which required the study team to be able to review its positions if necessary and justify them largely based on the maps. Based on the research some recommendations for better public map use are suggested in order to make better use of the potential of cartography in planning to facilitate learning and mediation between multiple perspectives and interest. Future research, using anthropological methods, observing the process of creation and use of maps in planning in action is suggested as important to move beyond the limitations of perspectives that emphasize maps as representations.
