  1. You also might want to check out The Northwest Trails Project.
  2. Just out of curiosity, do you happen to have City Nav NT maps on your Vista HCx? When I had NT maps, I had the same sorts of delays with the cursor on the map screen. I was able to make the problem go away three different ways: (1) Make sure that there are no City Nav waypoints in your list of 50 most recent finds. If all 50 in that list were user-generated waypoints or caches I had downloaded, the delays went away. If there were any CN NT waypoints (addresses, stores, restaurants, etc.) the lag came back -- the more CN NT waypoints there were, the longer and more noticeable the lag was. Strange but true... try selecting 50 of your own waypoints just to clear all CN NT waypoints from the Recent Finds list, and see if that makes a difference with the lag. If so, maybe you have the same problem that I had. (2) Remove the NT maps, either by having only topo maps on the SD card or taking out the SD card altogether. (The delays went away if I only had topo maps on the SD card.) This was not a permanent or practical solution, since I needed auto-routing maps, but it did help identify the problem for me. (3) Replace the NT maps with non-NT maps. This ended up being my permanent fix for the issue. Sorry, not NT maps. MGNA v7 with Metrogold. Plus tide points from GPSMAP 168. I have used it successfully to do turn-by-turn navigation for quite a while, with all kinds of address and POI waypoints in my recent finds, but the problem only recently appeared. I load geocaches one-by-one using the "send to GPS" function, and I'm wondering if I recently crossed some threshold. I did remove a handful of found caches and I haven't seen it show up since then. But, I haven't been using my GPS much lately, either, so I can't say definitively that the problem went away.
  3. I don't think anything can fix that hole.
  4. Yeah, you'll want to get MapSetToolkit working (sorry, I've never done it myself) because I'm pretty sure that Mapwel didn't include the routing information from City Navigator, which is a huge loss. As far as I know, only MapSource can combine and upload routable maps. It's possible sendmap could do it (www.cgpsmapper.com), but I don't know.
  5. Well, you do have to route to a cache off-road in order to be able to mark it as found, but you can save some keystrokes. While your "follow road" route is active and the map page is displayed, Press the Menu button and select Recalculate, then choose Off Road (your routing setup has to be configured for "Prompted"). You have to load them both at the same time. Look at MapSetToolkit to get your custom map into MapSource.
  6. Could it have been data from the different layers?
  7. www.openstreetmap.org It started in the UK because of the Ordnance Survey's restrictive copyright, and there's a big focus on comprehensive coverage. You can get the data onto your Garmin GPS using a program called mkgmap. There are projects in the works (I'm working on one) to create routable GPS maps from OpenStreetMap data.
  8. I guess I'll see what I get. By the way, do you have any examples of config files where you've removed the background polygon (made a transparent map)? Since I have City Navigator, I'd really like to do as you described and make this map set be transparent and remove the streets and just leave basically the contours and water features.
  9. Okay, I finally got around to trying this and I'm seeing some strange messages in the display. In the first part, I get warnings such as this: 00210107.mp(330268) : Warning W008: Element spans more than 10 degrees! Then later, I see: ****RGN40**** Elements to process -->153535 100% Processed -->105268 Split -->1283 Skipped because of wrong data -->4400 The "element spans more than 10 degrees" seems like a weird error. How is that possible when the segments themselves are tiny? And the "Skipped because of wrong data" is a bit concerning, too. I realize these are just warnings, but is it going to be missing data in the output? Any idea what might be causing these messages?
  10. ogr2ogr is your friend (www.gdal.org). Easy conversion between a wide variety of GIS formats. I looked at the site and all I found were things for raster conversions. But I could have missed it. The way I deal with .e00 files is I have an old (3.0) version of ArcView. I use the Import Utility to convert the files (which is a pain). The import utility creates files I can import into ArcView as a theme. I then save the theme as a shapefile. Then I add it in GPSmapedit. It works but is time consuming and a pain. Is there a better way out there? Just download and install the gdal package. ogr2ogr is part of those tools. A lot of the toolkit (the GDAL part) is focused on bitmaps but ogr2ogr is for vector data. It's a command-line tool, but once you get the arguments figured out (it's not too hard), conversion is quick and relatively easy. It can also reproject into whatever coordinate system you need at the same time (that's the -t option). If you have more than a couple files to work with, it's definitely worth your time to learn it.

  12. It's about dang time. I've been frequently seeing #1 directly overhead for quite a while but unable to get any signal from it, so it has been occupying one of my channels but not giving any position information. Good to get it out of the way. Bring on the new sats!
  13. Look at the free Garmin utility called nRoute--allows you to track your position on a laptop in real-time.
  14. Nice real-world test - I'm guessing that this log represents several hours of data, with over 800 m of elevation change, and in all probability, significant wind speeds and barometric pressure changes. 2 m accuracy should satisfy the needs of most recreational users! Is it too late to go back and place your own geocache at the top of the mountain? Oops. Now it's your turn to be wrong. He has the Legend HCx, which does not have a barometric altimeter. His excellent accuracy was with only GPS elevation available.
  15. Thanks. I was misunderstanding the barometric pressure as the absolute pressure.

  17. It is not a Topo map. It is a street map. Ah. Thanks for the info. I was thinking it was a topo I've decided that eventually I will add topo, I haven't decided quite how yet, but I will add it eventually. Dale You should be aware that there is another effort going on for 24k US Topo maps by IndyJpr, Oz and others, using SRTM DEM data, NHD water data and other data sources. You might want to coordinate with them to minimize duplication of effort.
  18. Thanks, Roy - more good data. Not to puncture anyone's balloon, but Roy's test didn't exercise the auto-calibration of anything. If I'm reading correctly, he was simply monitoring the pressure reported by his GPS and comparing it to the pressure broadcast by the weather service. All he proved is that the pressure sensor has good accuracy. That's (very) important and we do appreciate the data collection, but that's not where the auto-calibration comes in. The auto-calibration takes into account the elevation calculated from the GPS signals in order to correct for changes in pressure due to weather which would otherwise show up as elevation changes. Julianh's test is a good exercise of the auto-calibration function.
  19. I've had my Vista HCx since August 2007, but I just started having this problem, too. Long pauses when moving the cursor around the map. No recent changes in maps or firmware (I installed 2.60/2.60 shortly after it came out). I might try purging some waypoints/caches.
  20. Have the New Zealand maps been imported into OSM yet? Because just this week I updated a utility to transform routable Polish Format maps into OSM format. (here) My goal is to be able to go the other way--transform OpenStreetMap data into routable Garmin maps. I have plans, but little time.
  21. Thanks Pat for the quick reply. I tried that last night and it will only load 32,000 entries before I get an error. My shapefile has 125,000 entries (the entire state). Maybe I need to break it into smaller pieces using QDIS, save smaller files, convert each file using DNR Garmin, and then reload each one individually. Thanks again, Rick Try the free tool ogr2ogr, part of the FWTools kit (www.gdal.org or fwtools.maptools.org). You can reproject to GPX with WGS84 lat/lon using this command: ogr2ogr -f "GPX" -t_srs WGS84 outfilename.gpx infilename.shp Note that I haven't actually tried this particular command, but if it doesn't work exactly, some variation of it should. (You may have to use "EPSG:4326" instead of "WGS84").
  22. I've used it occasionally for quite a while, and as far as I can tell, it doesn't disable anything, and there's no annoying messages or anything like that. I think the main thing you don't get with the shareware version is the ability to show Google maps as a background image. But it's a great program so try it out and if you like it and you can, you should support the author.
  23. You're not really saving battery. Other users have tested the battery life with and without WAAS for the Vista HCx and it has a negligible effect. You'd lose more battery by clicking the backlight on a few times. So, if you're in an area that has WAAS coverage (in North America you're generally in good shape), just leave it on.
