About this app
Convert gps coordinates to 4000+ different coordinate systems, both projected and geographic, covering the whole world ( local systems, deprecated systems, almost every system ever used anywhere ). Cassini-Soldner, used in Italy, are implemented too. SUPPORT FOR GAUSS-BOAGA NOT RELIABLE, i'm currently working to fix it Simple to use: Select your target coordinate system and locate point in the map, below you can read coordinates in wgs84 ( map default ) and target coordinate system too ; to locate and translate current position, use GPS button You can save points and then export them in a csv file ( warning: many coordinate systems are valid only in limited geographic zone, you will see dashes if translation is not possible for the current point )
