Troubleshoot Data Import Problems

Potential Probems

There may be a metadata file in the data download (probably in a different directory if a single file download contains subdirectories.
There may be metadata on the web site where you downloaded.
For Geotiffs, use the MICRODEM option to look at the file. This has a different format than GDAL, and has some information that GDAL ignores, such as the vertical datum. The file must display for this to work.
For GEOTIFFS, JP2, PDF, ADF, you can use GDAL. Other than some Geotiffs, all of these files must go through GDAL.
The Resample menu has some options to correct or assign the datum and projection, and you can also use the GDAL command line.

Open quick vector map , and if the data set opens, File, Match other maps, Outline coverage area. This will show where the program thinks the data is and shows problems with the hemisphere, UTM zone, or the correct units for SPCS data in feet.
If the data set had to go through GDAL, run the command in a CMD window and look for error messages. The command will be in the debug log, which you must access before you reopen the program.
- If the file was a batch command, you must run the batch file from the CMD window.
- If the command was a single line, you must cut it and paste it into the CMD window and then hit enter.
If the program is not in the UTM projection or a geographic project, run it through GDAL WARP.

Open quick vector map , and if the data set opens.
MICRODEM only uses files in Geographic coordinates on the WGS84 datum, and should warn you if you need to reproject. You should try GDAL/OGR first, and then MICRODEM's option. You may have to determine the projection from the metadata.
