I have been using the following licensed products to publish my GIS data on web.
- web server: windows 2008 R2,
- GIS desktop: ArcGIS desktop,
- GIS web server: ArcGIS server,
- API: ArcGIS API for JS,
- Database: Oracle with ArcSDE,
- IDE: Eclipse.
But now I want to switch altogether to open source world mainly because of freedom. Fortunately there is plethora information about open source on web but unfortunately are confusing me a lot.
There are so many products like GeoServer, MapServer, OpenLayers, GeoTools, Vaadin, Geomajas, uDig, GRASS etc etc. I am not able to relate these products with the one I am already using.
Can someone please relate the equivalents?
