The Future of GIS Services in Academic Libraries: Exploring the Next Step

Kollen, Chris 06 April 2006 (has links)
Conference proceeding from the Living the Future 6 Conference, April 5-8, 2006, University of Arizona Libraries, Tucson, AZ. / In 1992, the Association for Research Libraries Geographic Information Systems (GIS) Literacy Project introduced libraries to GIS technology in response to the distribution of electronic geospatial data by the US Census Bureau and the availability of relative inexpensive GIS software. Since that time, there have been many technological and other changes that have affected the range of GIS services libraries provide, such as increased availability of online geospatial data, online interactive mapping, and integration of GIS into non-geography classes. What’s on the horizon? How will changes in libraries, technology, and GIS affect GIS services in libraries? The University of Arizona Library’s Arizona Electronic Atlas project, in consultation with other units on campus, is exploring how we can design a web-based “decision-support” geospatial tool that will help students and faculty analyze various scenarios or models to help make better decisions on various issues such as groundwater management, land use planning, housing development and wildfire prevention.

TRANSMISSÃO PROGRESSIVA DE MAPAS BASEADA EM GIS SERVICES / TRANSMISSION SCHEDULE OF MAPS BASED ON GIS SERVICES

Costa, David Cavassana 01 December 2006 (has links)
Made available in DSpace on 2016-08-17T14:53:16Z (GMT). No. of bitstreams: 1 David Cavassana.pdf: 893589 bytes, checksum: 3f41c9b2bbe82e8c81ee62e8eeb41a3b (MD5) Previous issue date: 2006-12-01 / The Internet has created an good environment for the sharing of geospatial data. In this environment users can transfer, visualize, manipulate and interact with these data sets. This environment not only provides new opportunities for the utilization of geospatial data, but also introduces new problems that should be addressed in order to provide an efficient and effective use of these datasets. One of such problems is related to the use of these spatial datasets in low transfer rate environments, what often becomes an impediment for the publication of those data in the Internet, given the huge volume of data to be transmitted. This paper presents a progressive transmission algorithm for vector maps on the Web, which uses techniques based on the resolution of the client device with the aim of reducing the amount of transmitted data, sending the data incrementally, thus gradually increasing the level of map details. Scale-dependent transmission techniques are combined with simplification and progressive ones, in order to maximize the overall system performance in a Web GIS environment. Furthermore, an architecture based on Web services is presented, that implements the progressive transmission of maps and allows a greater flexibility in the use of this functionality and in the development of clients in different computing platforms. / A Internet criou um ambiente adequado para o compartilhamento de dados geoespaciais, permitindo aos usuários a transferência, visualização, manipulação e interação com esses dados. Esse ambiente não apenas fornece novas oportunidades na utilização dos dados espaciais, como também introduz novos problemas que devem ser resolvidos a fim de possibilitar a utilização eficiente e efetiva desses conjuntos de dados. Um desses problemas está relacionado com a utilização dos dados espaciais em ambientes com baixa velocidade de transmissão, o que, devido ao grande volume dos dados espaciais, torna-se um empecilho para a disponibilização desses dados na Internet. Este trabalho apresenta um algoritmo para transmissão progressiva de mapas vetoriais na Web, que utiliza técnicas baseadas na resolução do dispositivo cliente com o objetivo de reduzir a quantidade de dados transmitidos, enviando os dados aos poucos, aumentando gradativamente o nível de detalhes do mapa. São combinadas técnicas de transmissão progressiva, simplificação e transmissão dependente de escala, a fim de maximizar o desempenho do sistema no ambiente Web. Ademais, apresenta-se uma arquitetura baseada em serviços Web que implementa a transmissão progressiva de mapas e possibilita uma maior flexibilidade no uso desta funcionalidade e na construção de clientes em diferentes plataformas.

Tjänstedesignäventyret : En kvalitativ undersökning hur design för tjänst kan tillämpas i kartläggning av organisationers värdeskapande processer / The service design adventure : A qualitative research of how design for service can be applied in mapping organizations' value-creating processes

Eriksson, Ebba, Aidanpää, Linnéa January 2024 (has links)
The purpose of the thesis is to apply the service design perspective to map value creation processes within digitally complex GIS-services. Services are becoming increasingly prevalent within organizations today, and it is crucial to continuously develop them to meet customer needs. Since existing services are used regularly, incremental development is required to maintain their relevance. By applying principles from service design, a deeper understanding of value creation processes within various digital services can be achieved. Utilizing the service design perspective in mapping the value creation processes of digital services is feasible, but it requires active involvement from all stakeholders. In this paper, we explore the application of the service design perspective using a combination of Soft Systems Methodology (SSM) and Service Blueprint as framework. By examining this combined framework with a focus on service design perspective on Geographic Information Systems (GIS-services), we contribute to expanding the research field of service design. The results indicate that mapping a value creation process using this approach is possible, but there is room for further improvement.
