Geodjango-Framwork-Based Population And Social Economic Information System For China, Wenlong Jing, Xiaodan Zhao, Yaping Yang, Jia Du, Xiafang Yue
Geodjango-Framwork-Based Population And Social Economic Information System For China, Wenlong Jing, Xiaodan Zhao, Yaping Yang, Jia Du, Xiafang Yue
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
We have constructed China population and social economic information system based on open source geographic Web framework GeoDjango. By comparing different WebGIS system structures, implementation patterns, spatial database management patterns and mainstream popular open source APIs, open source WebGIS framework GeoDjango, MVT pattern, Python and MySQL database, client-side browser framework openLayer were implemented. The database system utilized a Top-Down design method — DATAID-D to establish distributed database, and construct a uniform encoding standard, through normalized processes of the statistic yearbook, we constructed population and social economic database. This system has basic functions of web information publishing, spatial data storage, distributed …
Webgis-Based Natural Disaster Information System Of China, Jia Du, Yaping Yang, Xiafang Yue, Wenlong Jing
Webgis-Based Natural Disaster Information System Of China, Jia Du, Yaping Yang, Xiafang Yue, Wenlong Jing
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
We have constructed China natural disaster information system utilizing open source WebGIS framework. Through comparisons and researches on different WebGIS system structures, implementation patterns, spatial database management patterns and several popular software, open source WebGIS platform MapServer, PostgreSQL+PostGIS (spatial database and spatial data engine), client-side browser framework openLayer were used. This system have basic function of web information publishing, spatial data storage and management, and it collects natural disaster information that have been publishing on the internet through grabing internet information, and based on the analysis to the text information, different kinds of natural disaster information databases were constructed. Additionally, …
Web–Based Participatory Gis With Data Collection On The Field – A Prototype Architecture, Maria Brovelli, Marco Minghini, Giorgio Zamboni
Web–Based Participatory Gis With Data Collection On The Field – A Prototype Architecture, Maria Brovelli, Marco Minghini, Giorgio Zamboni
Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings
The rise of Web 2.0 and the current, unprecedented diffusion of mobile devices have laid new foundations for the development of PGIS (Participatory GIS). This study evaluates the possibility of exploiting FOSS (Free and Open Source Software) tools to build up a PGIS prototype providing Web publication of user field-collected data. Besides increasing public awareness and collaboration, user-generated content should also enlarge the knowledge of specific phenomena up to the local level. A prototype architecture was designed and tested in relation to a simple, planning-related case study, i.e., the report of road pavement damages. Open Data Kit suite was used …
