This application allows to convert KML, KMZ, GPX, CSV, Text files to AutoCad DXF format, allowing modify the coordinate system.
The KML, KMZ, and GPX files are beforehand in the WGS84 geographic system (Longitude-Latitude); in this case, on the left, we keep WGS 84, and on the right we select the output system; for example: UTM, Lambert, RGF93,… If the file to convert is in generic text or CSV format, you may not necessarily want to change the coordinate system, in this case, select the same system on the left and on the right, for example Lambert Zone I ➔ Lambert Zone I.
(Note: for the moment the local correction grids are not taken into account)
The application is under development, improvements will be made as and when I count on your feedback and suggestions.
