I have a project where I'm working with geographic raster images and I need to be able to do distance calculations between two points in the image. <br><br>I was thinking I could create a local SRS using a corner of the raster as the origin, then just transform from the lat/lon coordinates to the local coordinates (which would just be distance from the corner in meters) to make my calculations the most accurate. But I'm not sure if this is possible with OGRSpatialReference. Can anyone tell me how I could create a local OGRSpatialReference object with the origin of my choosing? Or maybe there's an easier way to do what I'm looking for.
<br><br>Thanks in advance,<br><br>Kevin Bentley<br>
