The third video of the fifth module is now available, in which we will talk about how to work with web services that don’t follow the OGC standards in gvSIG Desktop. These web services can be used to complement our maps with different layers.
Among these services we have OpenStreetMap, with which we have access to several layers. for example streets, nautical cartography, railroads, or cartography with different tonalities that can be used as reference cartography on our map.
Other available services are Google Maps and Bing Maps, where we can load different layers.
The requirement to load these layers in gvSIG (until 2.4 version) is that we must have the View in EPSG:3857 reference system, a proprietary system used by these services.
Besides, in order to load the Bing Maps layers, we will need to obtain a key previously, from the Bing Maps Dev Center.
Once we have these services, we can add our layers, reprojecting them to the view reference system. In addition, many OGC web services, such as WMS, WFS …, offer their layers in this reference system, so we can overlap them on our Bing Maps, Google Maps or OpenStreetMap layers.
