Hi all, I am happy to inform that I implemented a basic geometry reprojection for JTS geometries.
What is reprojection or transformation and why it is important? Basically changing the coordinate system CRS from one system e.g. WGS84 to another CRS system e.g. UTM Why is reprojection import: There are three possible areas of application: 1. The user wants to change the geometry CRS . 2. If using 2 geometries. e.g. distance measurement, both geometries has to be in the same CRS and if not, one geometry has to be transformed. 3. If special calculations are required that has to take place in a metric CRS like UTM, a backend projection has to be done. So far there are no JTS wrapper available, which can be used under Apache license. So I had to implement own methods to do so. This is so far working for Point, Line, Polygon and MultiPoint geometries. MultiLineString und MultiPolygon is a little bit more complicated and will be done later. Before committing this, the Apache SIS EPSG database has to be implemented we discussed before as a registration in web application containers. Greetings Florian
