USGS 7.5 minute topo DRG tiff to jpeg?

Postby rlridgeway » Mon May 24, 2010 6:34 am

What is the best method to import a USGS 7.5 minute topo Quad into pathaway?
The free drgs I have found are in the tiff format. I understand Pathaway accepts only jpeg and bitmap.
I understand I could convert the tiff to a jpeg but what about the projection file? The DRGS I have seen come with a tfw. Is there a simple way to convert the tfw to a JPR?

Are there free DRGs in the jpeg format that contain the JPR projection file for pre-calibration?

Or is it simpler to convert the tiff to jpeg, and calibrate with Map Manager?

PathAway Map Manager supports TIFF files now. (PNG, GIF too).

You can import the tfw file using the "Map->Read World File" option.
