Thanks for the info, not sure which way I"ll go, but I understand the options better.

I currently have City Navigator® North America NT 2008 and would like to upgrade to the newest version. I"m a little confused by the by the options I"ve found, I would like the dvd version to update my nuvi and handheld. Is this possible and how much should I expect to pay?

 The county I downloaded was 32 meg. I don't have anything to compare that to as far as creating contours. Thanks for the information.

I found this data at a NCGIS site, appears to be pre-made contour and elevation data for entire state.
If someone in the group with more experience than me would take a look at it might be useful.

Sorry that should have been 2gb.

I  recently updated this unit from Garmins web site. Part of the update was to allow maps greater than 2mb. I could not find any info on this. Could anyone explain this to me.
Thanks, Rick

I hate to be a pest, I have asked this question before. When processing .MP files with cgpsmapper I kept getting this, "warning: element should not be 0". I have determined that the problem is with the tiger data since it doesn't happen with contours or water data. I've check about 2 dozen lines in the .MP file that show this warning, they all look similar to this.

[RGN40]
Type=Invisible Boundary
RegionName=37
Data0=(35.812706,-77.451753),(35.812428,-77.452888),(35.812396,-77.453021),(35.813033,-77.456329),(35.813254,-77.457477)
[END]

The line number in question appears in front of [END].
"Type=Invisible Boundary" is common in all lines in question
I'm using Globalmapper but I'm not following the tutorial exactly. Can anyone tell me what I've done wrong or how to correct this. Thanks in advance, Rick

-OZ- The error I got was with postgis. I don't remember exactly, something about writing to a .dll, I posted it earlier under "postgis subject".

boyd - Thanks for the info, GM has turned out to be more complex than I first though it's going to take some time to figure it all out.

one more question: in cgpsmapper, what does this mean. "warning w024:element should not be 0"

Looks like I've gone as far as I can with making maps. I still haven't been able to install postgresql and postgis on my computer (vista). Thanks for the help.

Once GM completes contours how do I determine which are minor,intermediate or major? Or does it matter in the end product?

Also, how can I trim a map to get rid of overlapping data?

Thanks for the help, I'll keep working on it.

Thanks, that helped. Now this error popped up, I'll try to attach.

I have tried to install postgis with Application Stack Builder several times and I keep get this error
"ERROR 740: The requested operation requires elevation", and skips the installation of postgis. What am I doing wrong.

Hey I'm back, over the last few months I decided to play around with Globalmapper. I now have about 20 counties in the NE part of NC. I decided to break these up into 3 groups because of the differences in elevation (0 on the coast and 400 ft. in the western part). After completing each group I will combined them into one workspace and export to a MP file. Will this work out the way I expect it to, and if so can I add counties to the map later? Also, how large can these files get, one file is already over 500 mb.

FYI, work was done with GlobalMapper.
