NCGISguru Posted June 20, 2008 Share Posted June 20, 2008 (edited) Hi all, I'm new to the forum, but by no means new to GPS and GIS. I graduated last year from NC State and took many of the courses through their geospatial program. I have access to the ESRI Arc suite and have stockpiled all kinds of shapefile data. If anyone ever needs any NC shapefiles let me know! I haven't really gotten into geocaching per se; I use mine more for marking locations of reptile and amphibian (mostly snake) records as a personal herp log and to report findings to the NC Museum of Natural Sciences. I've recently been toying with creating the custom maps through GPSMapEdit, cGPSmapper, and M3 (those are the programs I use). I'm still pretty new to this topic, though it fascinates me, and I've hit a roadblock on one of my projects that I am seeking help about. I've successfully created a map of a couple of longleaf pine savannas (polygon layer created with ArcMap), loaded it to the GPS and it worked great. My current project is trying to load a layer of Natural Heritage sites (statewide polygon layer) to the GPS. I've gotten all the way through the map building process and sent it to the GPS via MapSource and it fails to show up in the GPS. I suspect it’s a "levels" problem, but the problem is I don't know how to rectify that. Can anyone provide some guidance? Here is some general info: GPS: Garmin GPSMap 60CSx SHP: NC Natural Heritage Significant Areas (roughly 30k polygons across the state) SOME SCREENSHOTS: Like I said; the map compiles fine and then doesn't show up in the GPS itself. When I import the shapefile, it only has level 0 and I add the other levels and import the same shapefile to populate them as well (the map disappears as I add new levels. Am I even doing that part right? I've tried compiling the map with just the level 0 as it comes with, but I get an error saying that the detail is too high I believe. Also, I've noticed that sometimes in the .img version of the map, the "mini preview" screen in the top left corner of GPSMapEdit will be all black except for a tiny box in the middle, which is I'm assuming my map. Which setting am I getting wrong? Levels, limits? Is the shapefile too big? Is there a "too big?" Any general info will be great as well. Thanks for any help!
