WebRAS Mapper is a dedicated interface for visualization and processing of geospatial data. Before geometry generation, it is necessary to create the basic conditions to develop geospatial features. These include specifying a coordinate system. The coordinate system defined by the projection file needs to be a projected coordinate system.
