Well, next problem. I got all the maps to compile, but now when I run Mapsettoolkit I get an error E024 "Top layer detail level too high to cover entire map - decrease detail level of the less detail layer (use higher Level#)." I've played with layer setting until I was blu ein the face and can't figure this out. Anyone got any ideas?

I know you can remove the duplicates in Map Edit, but Map Edit has issues for an area as large as Texas too, it will not display all the data, nor will it save it. The duplication isn't in a single file, rather the NHD basins overlap - at least for Texas. I've got 219 basins, it would take a lot of work to figure out which basins overlapped. As for the "dozens of clicks", I downloaded MacroExpress to help with that area. Really saves the day when working with large datasets. So, for now, I created my separate layers in ArcMap, clipped everything down to just Texas (the NHD data also included data for Louisiana, Arkansas, Oklahoma and New Mexico, even though I specified just Texas), created a grid that covers Texas (25x35 rows) and split the coverages based on that grid. Then I created a program in C# that would created the default .mp file and preload it with a "dummy" polygon and the default levels (Map Edit will not load an empty map). That allowed me to create all the .mp files for my tiles. THEN I created another program that would take the "next" tile and move the SHP files over to a standard directory, that way Map Edit could always look in the same directory for it's files. This application would load up Map Edit with the current .mp file. Then my macro would load the SHP files, specify the type, specify the layers, remove duplicates, remove the "dummy" polygon and save the .mp file. The last step would be to run the C# app I created above then start the macro over. So, up to this point everything has pretty much been automated. Now I'm waiting for cGPSMapper to create the image files. The "automated" portion of this process has taken over 24 hours, I estimate the cGPSMapper portion to take another 48 or so hours. I started out with 249 basins, I now have 419 tiles without duplicated data and about half the data as the basins contained since I'm only working with Texas data.. Hopefully it'll work without fits this time. I also figured out the querystring for the NHD data and wrote ANOTHER C# app that downloaded all the data for Texas automatically. I'm a programmer by trade, so I try to find a better way to do all this repetitive stuff. If I can get the Texas data to work I'm planning on creating the data for the whole US and making it available. IF this works I'm also planning on overlaying DEM data, but I'd also like to find reliable road, trail and rail data in SHP format. I'm trying to create a high def area and topo map for Texas that resembles the 24K topo as close as possible, the topos are a god send when hunting.

Thanks. After two weeks worth of work I found out that the basin files as downloaded from the NHD website contain a lot of overlap which throws cGPSMapper into fits trying to compile the mapset for use in Mapsource. I'm going to take a different route now, I'm going to throw everything into ArcMap then split the shape file into grids and try everything again. I'll holler back if I have any other problems. Texas is so BIG.

I've got 293 files that contain high-def hydro data for Texas. Out of those files I'm having problems with about 70 of them, cGPSMapper just sits there. On a 1K file I waited two days and there was no progress at all, it just sat there. Is there anybody on here that can help me figure out why this is happening? I've got two files I can send a link too. Thanks!

I'm not sure which one to send you, I'm working with a set of a little over 3500 .mp files. I've got more issues though, when I save all the .mp files that dem2topo makes into a single .mp file it saves just fine, but when I load it back up I only see about 5 contour lines, a far cry from what should be there. After playing around with this I finally got GPSMapper to export. What I did was change the contour intervals from 20,200,500 feet (as mentioned in the .pdf) to 40,200,1000 as mentioned above. Finally, some progress. HOWEVER, I started looking closer at the map and noticed a lot of spots where the contour lines weren't matching up, like they were offset a bit. This whole process is very frustrating. Now to mention I've been waiting for about a week for my hydro data. I was relying on the high res hydro data to point out some good hunting spots deep in the woods. I would be happy to send whatever files you need to pinpoint the issue, but I'm not sure which files out of my working set to send, as I said, I'm trying to compile a high-res topo/hydro map for the entire state of Texas.

No, that's not it. Even when I get this error I can select Level 0 in Map Edit and see the entire map. I do this from habit now before saving the map. I've also never entered something before Level 0 in the Levels page, I've always added them at the bottom. What's worse, I can trim out portions of the mp and leave all the settings alone and get around this error, so it's not a setup or configuration problem.

Guys, I've been trying for two weeks to create some topo/hydro maps for Texas to no avail. I'm getting two errors and can't seem to figure out what's going on. I've followed the guide exactly as it's written. The first error is "Layer 0 of the map cannot be empty". If I crop out sections of the map I can make this error go away. I've re-downloaded and reprocessed the "problem" files through dem2topo and still get this error. The second error I get when I trim the map down to an area around Davey Crockett National Forest. The error was posted on the page by "Cobber99" but nobody posted a fix - the error is "Bad Allocation" during processing by cGpsMapper. I cannot get around this error. Are there any ideas out there on how to fix these problems? I'm more concerned with fixing the second issue since I can work around the first. I would really like a 10m topo of Texas, but all I really need is a 10m topo of my hunting grounds to be happy. Thanks in advance!
