Spatial Data Explorer: Providing Discovery and Access to Geospatial Data at the University of Arizona

Kollen, Christine 25 June 2016 (has links)
Presented at the 2016 American Libraries Association Annual Conference / The University of Arizona (UA) Libraries has been providing GIS services and access to geospatial data since the 1990's, first by providing access to US Federal Depository Program geospatial data on CD-ROMs and DVDs, later through the Arizona Electronic Atlas and more recently the UA Institutional Repository (UAiR) and the UA Campus Repository. Focus groups with faculty and staff confirmed our view that neither the UAiR nor the Campus Repository meet the needs of the UA's GIS community. To address their needs, the UA Libraries investigated various solutions for developing a geospatial data portal that would facilitate discovery, access, sharing, and retrieval of distributed geospatial data resources and consolidate several repositories at the University into one accessible and modern interface. An inventory was completed, interviews were conducted with relevant campus stakeholders and geospatial data portal managers at various academic libraries, and various options were investigated. Based on several factors, the UA decided to implement Open Geoportal (http://www.opengeoportal.org), a collaboratively developed, open source, federated web application for discovering, previewing, and retrieving geospatial data from multiple repositories. The UA Libraries released the resulting geospatial data portal, Spatial Data Explorer (SDE), in the fall 2015. In anticipation of the release, a survey was conducted in spring 2015 of faculty, staff, and students to gauge interest in contributing data to the SDE. The poster will include why we decided to implement Open Geoportal, screen shots showing the SDE interface and functionality, results of the survey and follow-up interviews with potential contributors, and use statistics.

Proposta de tratamento e modelagem de dados espaciais para uso em infraestrutura de dados espaciais - IDEs: estudo de caso de macrobentos para a área costeira da Baixada Santista. / Proposal of processing and database modeling of spatial data infrastructure -SDI: macrobenthos study case for coastal zone of Santos metropolitan region.

Carvalho, Gabriel Niero de 12 August 2013 (has links)
As zonas costeiras são áreas complexas que contemplam ambientes terrestres e marinhos que, além de possuírem enorme riqueza ambiental, também são áreas atrativas aos seres humanos por oferecer alimentos, lazer, negócios, transporte, entre outros. Algumas dificuldades de gerenciamento ocorrem pela complexidade, conflito de interesses e pelo fato de não haver padronização no levantamento de dados e disponibilização para a comunidade científica, órgãos públicos, etc. O uso de geotecnologias pode auxiliar na organização, padronização e compartilhamento destas informações em Atlas Web além de apoiar no planejamento e tomada de decisão pois agregam, em um único ambiente, diversos dados provenientes de fontes distintas. A construção de um modelo de dados espacial voltado à área ambiental, para ser utilizada em Infraestrutura de Dados Espaciais (IDE) é exemplificada a partir da modelagem de um bioindicador, Macrobentos, de qualidade de sedimentos. Este trabalho apresenta as etapas necessárias para a construção de modelo de dados espacial de Macrobentos e emprega a Região Metropolitana da Baixada Santista como referência, além de ilustrar e discutir as principais dificuldades para organizar os dados não padronizados. Conclui-se que a estruturação do conhecimento quando se trabalha com dados ambientais em um modelo é essencial para sua posterior integração em IDE. Constatou-se no processo de modelagem que questões metodológicas relativas ao processo de coleta podem dificultar ou até mesmo inviabilizar a integração de dados provenientes de diferentes estudos. A construção de um modelo de dados espacial e sua posterior publicação via Geoportal, como o apresentado neste estudo, poderá ser utilizado como referência para novas pesquisas com objetivos semelhantes. / Coastal zones are complex areas that include marine and terrestrial environments. Besides its huge environmental importance, they also attract humans because they provide food, recreation, business, transportation, among others. Some difficulties to manage these areas are related with their complexity, diversity of interests and the absence of standardization to collect and share data to scientific community, public agencies, among others. The use of geo-technologies can be used in the organization, standardization and sharing of this information through Atlas Web and assists planning and decision making issues because it aggregates different files from distinct sources. The construction of a spatial database integrating the environmental business, to be used on Spatial Data Infrastructure (SDI) is illustrated by a bioindicator, Macrobenthos, that indicates the quality of the sediments. This research shows the required steps to build Macrobenthos spatial database based on Santos Metropolitan Region as a reference. Besides, it tries to illustrate the problems related to organize non standardized data. It can be concluded, when working with environmental data, that the structuring of knowledge in a conceptual model is essential for their subsequent integration into the SDI. During the modeling process it can be noticed that methodological issues related to the collection process may obstruct or make impracticable the data integration from different studies of the same area. The development of a database model and its subsequent publication in a Geoportal can be used as a reference for further research with similar goals.

Vizualizace historického vývoje katastrální mapy / Visualizations history of changes in cadastral map

Klecanda, Vojtěch January 2015 (has links)
The goal of this master thesis is to suggest a methodology for a visualization history of changes in cadastral maps. The suggested methodology takes into account a selection of original historical and contemporary data, processing workflow and follow-up visualization using existing open source web technologies. The greatest contribution of this thesis is in the design of the spatio-temporal database, because currently there does not exist workable editor similar to it, which could be used for creating such data. The suggested procedure is based on database updating method of ISKN database utilizing amendment records. However this method is significantly simplified with the use of PostgreSQL/PostGIS geospatial functions. The available literature and other informational sources to the topic are overviewed in the first part of the master thesis. The term "spatio-temporal data" is thoroughly defined and also the ways of integrating temporal features into spatial data, methods of visualization of spatio-temporal data and recent state of their implementations into desktop platforms and web applications are noted. Furthermore historical and current data sources and their usability for the master thesis are described. The full methodology of pre-processing and processing of data and a subsequent visualization using...

Pruebas de inscripción de representaciones gráficas en España, y estudio y creación de herramientas técnicas para la aplicación del LADM en Colombia

Velilla Torres, Joan Manuel 02 September 2024 (has links)
[ES] Esta tesis versa sobre la gestión de propiedad en el Catastro y el Registro de la Propiedad en España y en Colombia; a través de las herramientas técnicas que utilizan los profesionales que delimitan la propiedad en el terreno. Desde un punto de vista práctico se inició el estudio en España con la coordinación entre el Catastro y el Registro, aplicando con un caso práctico la ley 13/2015, justo en el momento en el que fue aprobada. Para testar la ley se realizó la delimitación de una finca con su representación gráfica alternativa, y se llevó a una notaría. Se comprobó que esta vía no era viable todavía, y se actualizó la cartografía catastral por el cauce tradicional del Catastro. Posteriormente, en Colombia se ha estudiado una iniciativa de puesta en marcha de la norma ISO19152- LADM, cuyo perfil de aplicación en Colombia se ha denominado LADM-COL. Para la aplicación del perfil el gobierno colombiano ha realizado un desarrollo que ha estado en constante cambio durante el tiempo de investigación de esta tesis, y que incluye un plugin para QGIS, denominado LADM-COL. Este plugin permite introducir los datos de una delimitación de una propiedad colombiana (finca en España, predio en Colombia) según el modelo LADM-COL en una base de datos local, que luego es exportada para ser incluida en otra base de datos global y oficial. Está previsto que los datos de esta base de datos sean publicados en un geoportal, que en el momento de desarrollo de esta tesis, aún no está disponible. Esta tesis realiza un estudio de la metodología de trabajo diseñada para la captura de datos en el modelo LADM-COL en Colombia, mediante el plugin de QGIS LADM-COL. Para realizar las pruebas se ha contactado con la asociación de topógrafos denominada Cámara Colombiana de la Topografía, estableciéndose una colaboración, de forma que se usará esta tesis para fomentar la captura de datos de delimitaciones topográficas según el modelo LADM-COL. Se ha planteado, junto con la asociación de la Cámara Colombiana de la Topografía, la creación de un visor-geoportal que permita visualizar y consultar la información geográfica y alfanumérica de los trabajos realizados según el modelo. Para ello, se instalaría la base de datos con el modelo LADM-COL en la nube, permitiendo su conexión directamente con QGIS. Los usuarios importarían sus trabajos en la nube y se mostrarían en el geoportal. Los usuarios, previamente identificados, podrán acceder a la información del geoportal, para la consulta de la información. El objetivo del geoportal es poder mostrar los datos capturados, mientras el geoportal oficial no esté disponible, y poder valorar la utilidad de este geoportal en aspectos como: si facilita la regularización de tierras, si facilita la compresión de los trabajos de regulación, si añade seguridad, o bien, si por el contrario representa una tarea extra poco útil. La principal conclusión de este trabajo es que, a pesar de las dificultades técnicas para acordar los modelos de datos, y de las complicaciones del diseño y desarrollo de herramientas para la gestión de la información catastral y registral (bases de datos, geoportales, comprobaciones topológicas y temáticas, herramientas de edición e intercambio, etc.), dichas herramientas son desarrolladas adecuadamente, y a pesar de ello no se consigue que se implante su uso. Los motivos que se han detectado son la falta de información de los propietarios, y la falta de información y formación por parte de técnicos y juristas en un tema, el de la delimitación de la propiedad, que exige que todas las partes implicadas conozcan un poco todas las partes del proceso de delimitación de una propiedad, derechos, registro, legislación, trámites administrativos, e incluso el modelo de datos con el que se está trabajando. / [CA] Aquesta tesi versa sobre la gestió de propietat al Cadastre i el Registre de la Propietat a Espanya i Colòmbia; a través de les eines tècniques que utilitzen els professionals que delimiten la propietat al terreny. Des d'un punt de vista pràctic es va iniciar l'estudi a Espanya amb la coordinació entre el Cadastre i el Registre, aplicant amb un cas pràctic la llei 13/2015, justament en el moment en què va ser aprovada. Per testar la llei es va realitzar la delimitació duna finca amb la seva representació gràfica alternativa, i es va portar a una notaria. Es va comprovar que aquesta via encara no era viable, i es va actualitzar la cartografia cadastral per la llera tradicional del Cadastre. Posteriorment, a Colòmbia s'ha estudiat una iniciativa de posada en marxa de la norma ISO19152-LADM, el perfil d'aplicació de la qual a Colòmbia s'ha anomenat LADM-COL. Per a l'aplicació del perfil el govern colombià ha realitzat un desenvolupament que ha estat en canvi constant durant el temps d'investigació d'aquesta tesi, i que inclou un plugin per a QGIS, anomenat LADM-COL. Aquest plugin permet introduir les dades d'una delimitació d'una propietat colombiana (finca a Espanya, predi a Colòmbia) segons el model LADM-COL a una base de dades local, que després és exportada per ser inclosa a una altra base de dades global i oficial. Està previst que les dades d'aquesta base de dades siguin publicades en un geoportal, que en el moment de desenvolupar aquesta tesi encara no està disponible. Aquesta tesi realitza un estudi de la metodologia de treball dissenyada per a la captura de dades al model LADM-COL a Colòmbia, mitjançant el plugin de QGIS LADM-COL. Per fer les proves s'ha contactat amb l'associació de topògrafs anomenada Cambra Colombiana de la Topografia, establint-se una col·laboració, de manera que s'usarà aquesta tesi per fomentar la captura de dades de delimitacions topogràfiques segons el model LADM-COL. S'ha plantejat, juntament amb l'associació de la Cambra Colombiana de la Topografia, la creació d'un visor geoportal que permeti visualitzar i consultar la informació geogràfica i alfanumèrica dels treballs realitzats segons el model. Per això, s'instal·laria la base de dades amb el model LADM-COL al núvol, permetent la seva connexió directament amb QGIS. Els usuaris importarien els seus treballs al núvol i es mostrarien al geoportal. Els usuaris, prèviament identificats, podran accedir a la informació del geoportal per a la consulta de la informació. L'objectiu del geoportal és poder mostrar les dades capturades mentre el geoportal oficial no estigui disponible, i poder valorar la utilitat d'aquest geoportal en aspectes com: si facilita la regularització de terres, si facilita la compressió dels treballs de regulació, si afegeix seguretat, o bé, si per contra representa una tasca extra poc útil. La conclusió principal d'aquest treball és que, malgrat les dificultats tècniques per acordar els models de dades, i les complicacions del disseny i desenvolupament d'eines per a la gestió de la informació cadastral i registral (bases de dades, geoportals, comprovacions topològiques i temàtiques, eines d'edició i intercanvi, etc.), aquestes eines són desenvolupades adequadament, i malgrat això no s'aconsegueix que se n'implanti l'ús. Els motius detectats són la manca d'informació dels propietaris, i la manca d'informació i formació per part de tècnics i juristes en un tema, el de la delimitació de la propietat, que exigeix que totes les parts implicades coneguin una mica totes les parts del procés de delimitació duna propietat, drets, registre, legislació, tràmits administratius, i fins i tot el model de dades amb què sestà treballant. / [EN] This thesis deals with property management in the Cadastre and Property Registry in Spain and Colombia; through the technical tools used by professionals who delimit the property on the land. From a practical point of view, the study began in Spain with the coordination between the Cadastre and the Registry, applying law 13/2015 with a practical case, right at the moment it was approved. To test the law, the delimitation of a property was carried out with its alternative graphic representation, and it was taken to a notary office. It was found that this route was not yet viable, and the cadastral cartography was updated through the traditional Cadastre channel. Subsequently, in Colombia an initiative to implement the ISO19152-LADM standard has been studied, whose application profile in Colombia has been called LADM-COL. For the application of the profile, the Colombian government has carried out a development that has been in constant change during the time of research of this thesis, and that includes a plugin for QGIS, called LADM-COL. This plugin allows you to enter the data of a Colombian property delimitation (farm in Spain, property in Colombia) according to the LADM-COL model in a local database, which is then exported to be included in another global and official database. It is planned that the data from this database will be published in a geoportal, which at the time of development of this thesis is not yet available. This thesis carries out a study of the work methodology designed to capture data in the LADM-COL model in Colombia, using the QGIS LADM-COL plugin. To carry out the tests, the association of surveyors called the Colombian Chamber of Topography has been contacted, establishing a collaboration, so that this thesis will be used to promote the capture of data on topographic delimitations according to the LADM-COL model. The creation of a viewer-geoportal that allows viewing and consulting the geographical and alphanumeric information of the work carried out according to the model has been proposed, together with the association of the Colombian Chamber of Topography. To do this, the database with the LADM-COL model would be installed in the cloud, allowing its connection directly with QGIS. Users would import their jobs into the cloud and display them in the geoportal. Users, previously identified, will be able to access the information from the geoportal, to consult the information. The objective of the geoportal is to be able to show the data captured, while the official geoportal is not available, and to be able to assess the usefulness of this geoportal in aspects such as: if it facilitates the regularization of lands, if it facilitates the compression of regulation work, if it adds security, or, on the contrary, it represents an extra task that is not very useful. The main conclusion of this work is that, despite the technical difficulties in agreeing on data models, and the complications of the design and development of tools for the management of cadastral and registry information (databases, geoportals, topological checks and themes, editing and exchange tools, etc.), these tools are adequately developed, and despite this their use is not implemented. The reasons that have been detected are the lack of information on the part of the owners, and the lack of information and training on the part of technicians and jurists on a topic, that of the delimitation of property, which requires that all parties involved know a little all parts of the property delimitation process, rights, registration, legislation, administrative procedures, and even the data model with which you are working. / Velilla Torres, JM.
