the project
geojsp is an open source (
GPL) component that integrates geographic elements in your business intelligence infrastructure (geo-BI).
The project was developed by
Inventis.
Integrating geojsp in your architecture will allow you to retrieve the relevant information in order to generate:
- thematic maps
- flow maps
- indicators
- graphics (bar charts, pie chart, etc.)
prerequisites
In order to use geojsp, you will need an installation of
postgreSQL database with
postGIS as well as an
Apache Tomcat 6 server.
Currently, only the connection to PostgreSQL / PostGIS is supported. We plan to add some more in the further releases.
Additionnal knowledge :
- To use geojsp, the user must know how to build a Spatial OLAP (SOLAP) data cube, containing at least one dimension and one measure. Don't panic, we'll provide you one in the download package, so you can use it anyway.
system architecture
| geojsp is a servelet that allows to connect to a postgreSQL database containing geospatial features (with PostGIS), query the data via MDX queries and encode the geometries in GeoJSON format in order to display it in a OpenLayers web-mapping interface. |
 |
| geojsp is compiled with the SOLAP server GeoMondrian in order to create MDX queries incorporating a spatial component. geojsp also includes JFreeChart, a graphic generator used to display graphs superimposed on geographical elements. |

download
geojsp download package contains the following:
- a geographic dataset to be inserted in your postgreSQL/postGIS databse (modified dataset from data.un.org)
- the data cube schema (XML format)
- geojsp .war file to be deployed on your Apache Tomcat server
- an pre-built OpenLayers interface to start building your own queries and interface
