I am using ogr2ogr to reproject a shapefile. Here is what I have done.
- I have a shapefile A.shp. I used the following command to create B.shp:
ogr2ogr -t_srs EPSG:3857 B.shp A.shp
- Now I reprojected B.shp again and created C.shp
ogr2ogr -t_srs EPSG:3857 C.shp B.shp
Since B and C have same data and they are in same projection, I think they should completely overlap. However the do not. In the image bellow the Red one is A.shp and the other one is B.shp.
Is there a good reason why this can happen? This is happening to all the shapefiles not just this one.
