Abstract

Statistical data on population, education, health, ... are summarized and distributed in tabular form. By allowing users to select, integrate and display these data on map, as well as perform single-variable or multivariate classification without needs of professional software, they can have a deeper understanding of spatial distribution of statistical value as well as can find out groups of data with similar characteristics. To illustrate this idea, a WebGIS is developed based on open source GeoServer, OpenLayers softwares. Data used for the illustration are statistical data from statistical office in Ho Chi Minh city and administrative boundary map. These data are organized and stored in PostgreSQL-PostGIS database. Through this WebGIS system, users with certain knowledge of data analysis can completely perform statistical analysis and display them on an internet-based map for their own purposes.
