Title: NE USA Topo Part 1
Post by: Snake Eyes on September 02, 2009, 07:43:52 AM

I downloaded this map set and have uploaded the sections I need to my 60CSx. Nice!

Now I would like to delete most of the .img files from the folder on my hard drive since I do not need maps of all that area, (and am working with a 60gb drive.) Is there a way to see which areas of the map are contained in the individual files? And if so, can I delete them without losing function of the rest?

thanks for any help.

According to the description of the mapset the author included on gpsfiledepot - it was immediately above where you clicked to download the mapset:

Quote
The img file names do have meaning.

Position 1 and 2 The block number. Blocks 4 degree by 4 degree parts I have divided the map in to.
Position 3 and 4 The Latitude of the Northwest corner of the square
Position 5, 6 and 7 The Longitude of the Northwest corner of the square
Position 8 A number 1 to 4 showing what quarter of the degree the img file map is of . 1 is the Northwest, 2 is the Northeast, 3 is the Southwest, and 4 is the Southeast,

In some testing I did a year ago, all of the actual data files do not need to be present. Write the files to a CD. If you ever need those files, simply copy them back to the folder with the other files on your hard drive.

Thanks! I think I can work that out.

I have another question.
After I deleted the mapset called New York Topo, Mapsource refused to open, and requested that I reinstall that mapset.

What's that all about?

Thanks again.

A mpaset should not be delete. It should be uninstalled by using the uninstall 'utility program' which came as part of the selfinstall version. I would try reinstalling the mapset, then use the uninstall program. There are other ways, but they are 'more complex.

Thanks Maps ...

I didn't really "delete", I just moved the folder as a test. When I put it back, Mapsource was happy.

But I did delete another mapset, called NewEnglandtopo, and Mapsource did not complain about that.
Do you think I need to reinstall NewEnglandtopo and uninstall?

I noticed that when I saved a map from NewEnglandtopo, it was a .gdb file, but when I save a map from New York Topo, it is a prn.

Thanks for your help, I will work on this.
