I am trying to convert SHP to GeoJSON to work with Google Maps API's data layers.
I am working with ogre (I also tried mapshaper, but it always give bad coordinates). When I convert SHP with WGS84 format, the conversion works fine. However when I try to convert MTM3 and UTM6 SHP formats to GeoJSON, the coordinates are all screwed up.
Bad coordinates example:
I notice that on the ogre website, there are optional fields for Source SRS & Target SRS. Am I suppose to add something there to get UTM/MTM conversions to work?
