  1. I was shuffling things around to salvage some disk space and in the process lost my CNNA7.img file. Now MapSource won't even start and I lost my CNNA7 disk in a move. Could anyone send their CNNA7.img file to ejnewman at gmail dot com? I still have all the files for the detailed map sections, CNNA7.tdb, and CNNA7.mdx; I'm only missing that one img file.
  2. I've made quite a few homemade topo maps without any problems.
  3. The google maps site has been running a bit slow the last few days.
  4. The only reason you would ever need to use magnetic north for geocaching was if you were getting a heading from your GPS to use with a regular compass that doesn't have its own declination adjustment. If you only use your GPS to find caches then it doesn't matter.
  5. I don't think "go to" is what you want. Somewhere else there should be an option to add a waypoint where you can punch in a latitude and longitude.
  6. You can also do that through a search & replace in MS Word. Somewhere in the dialog for that there is a place where you can pick non-text characters (like a line return or paragraph mark) so you can search and replace across lines. You just have to make sure to save the file as plain text (and with the .mp extension) and not as a .doc.
  7. I also have a Vista Cx and have never had problems with reception.
  8. The GPS can tell you which way is north as long as you are moving, so most people don't need to pay extra for an electronic compass. It is very handy for geocaching however, because you can stand in one place and see where the arrow for the cache points.
  9. Might it have something to do with the ProductCode? I'm not sure exactly how that works.
  10. http://research.microsoft.com/mapcruncher/ This lets you do exactly that to overlay your own pictures/maps on live.local.com.
  11. That is because the people making the mapping programs also sell ways of viewing those maps (printed atlases or GPSrs). They aren't going to provide their customers with a way to avoid buying more of their products.
  12. So you can have a GPS as long as it isn't mounted somewhere that could block your view. Makes sense to me.
  13. I like WW's controls a lot better. Google's work backwards from every other 3d app in the world.
  14. Yes, you can rotate and cant the angle of the display in Google Earth. Additionally, in cities, high-rise buildings are displayed quite effectively. The bird's eye view pictures aren't the same thing. In google you can tilt the view, but you are still looking at pictures taken from directly above. The bird's eye pictures are taken at an angle, i.e. looking at the side of a building instead of the roof.
  15. There are actually higher-res pictures of the entire US that google doesn't use, probably because they are black & white and 5-10 years old.
  16. The reason those files are pipe-delimited is because is it possible for the data in it to contain commas, but unlikely that they will contain a "|". Before you convert it to CSV you should probably do a search & replace to get rid any commas that might already be in there that would break the CSV when you try to load it in another app.
  17. If the hardware/software industry has taught us nothing else, it's that buying something assuming that the "promised" support or upgrade will be released in a timely manner is an absolutely terrible idea.
  18. If you can get it to display what you want then there is always the print screen button.
  19. Probably 0.0001% of the GPS users on this forum have Arcview, or know someone who does.
  20. This was supposed to be out in January. Don't hold your breath for their most recent guess for a release date. I also hear that the initial release won't do vector data at all. How exactly is it easy to convert e00 to shapefiles anyway?
  21. Polish (.mp) map files are ascii too, Garmin's .img files are the only things that aren't. It looks like mapdekode does the same thing as mapedit, but mapedit does it graphically while mapdekode just shuffles around the numbers in the map file. Either way, you still need to compile the result into an .img file using cgpsmapper or something similiar. That step is required no matter what method you use to edit the map itself.
  22. Here's the page on how to create your own maps: http://home.cinci.rr.com/creek/garmin.htm Some of the tools there (all of them are free) might be helpful. Mapedit can open and edit Garmin's .img files, but you might have to save the changed map as .mp and then recompile it to .img with cgpsmapper after you make your changes. I've never tried modifying a Garmin map. Probably the easiest way to add trails would be to make them a seperate, transparent map that can overlay whatever is already on the GPS without having to try to modify any of Garmin's maps.
  23. Maybe if it affects the battery. Not enough to matter I would think, but maybe a tiny bit.
  24. I'm guessing there won't be anything pre-made. The closes you will probably get will be downloading elevation data for the areas you are interested in from seamless.usgs.gov and generating your own topo maps. Those will just have topography though, no rivers or roads or anything like that. I suspect that anyone taking a camping trip in Afghanistan these days will be provided with better and more up-to-date maps than you could put on your gps anyway.
  25. If all you are going to do is look at the gps to see where you are then it doesn't really matter which datum you use. For geocaching you will have to stay with whatever datum the cache coords are presented in (WGS84). If you wanted to use the gps to get your current location and plot it on another map then you would need to make sure that the gps is set to use whatever datum the other map is in. Even if the datums don't match though, the error might still be small enough to not matter depending on what scale the other map is.
