I'm new at GIS. I am trying to make a java application that can display a map with certain points. I have achieved this using the geotools library. However, I want to put the map from OpenStreetMap or Google Streets in the background also. I already know that PostGIS can be used with GeoTools. However I don't know where to start. How is the best way to start once I have installed PostGIS?
Hello, I have also come across KML. I'm sorry I'm a beginner. What KML parsing mean, and how can I use this to show a map in my Java Application?
