  1. I wasn't aware that Garmin ships free. I wonder if I'd get hit for sales tax? Anyway, if GPS City doesn't come through (And I've had good luck with them in the past) that gives me an option. With REI I'd be paying sales tax for sure as they have stores in PA.

    But, if you have an REI membership, you'll get 10% back as a dividend at the end of the year. (Plus, you can take it back if anything ever goes wrong with it.)

  2. I checked Amazon today and they had raised the price of the 64s to $340 (and an even bigger hike on the 64st). I thought I better get moving so I ordered a 64s from GPS City for $300 (Where I bought my Oregon 600 - free shipping and no tax). Amazon's price hike may not be a trend as their prices can be volatile, but I thought I'd grab a 64s for the $300 price just in case.

    Garmin's site is still showing the new lower prices that appeared last week ($250 for the 64, $300 for the 64S, etc.). I'm guessing it's a permanent change... I'm just waiting for REI to catch on, so I can get the 10% dividend plus a 5% bonus for paying with their Visa card.

  3. I have updated GPS Visualizer's "KML Overlay" tool to make it more compatible with the new Garmin update.

     

    Here's an input form if you want to start from a GPS data file or from a pair of coordinates: http://www.gpsvisualizer.com/kml_overlay?garmin_custom_map=1

     

    And here's a new Garmin-friendly "network link" for use inside Google Earth: http://www.gpsvisualizer.com/google_earth/...twork_link.html

     

    The .kmz files that GPS Visualizer creates (with USGS or NRCan topos inside them) should work right out-of-the-box with the new Garmin software. Please let me know if something goes awry.

  4. Yeah, there doesn't seem to be any easy way to do this that I've found. However this overlay tool works very well for USGS Topos and the B/W orthos (I know this probably doesn't help our friends in Canada!).

    You need to save the file locally first but it is a pretty easy way to get topo tiles on the unit.

    I don't have a fancy new Garmin unit to test it with, but I think it might work without any extra steps if you select "Static" for "Ground Overlay type" in GPS Visualizer's KML Overlay input form.

    And as I think someone else mentioned, Canadian topo maps are indeed available. They're not as nice as the USGS topos (or MyTopo.com tiles), but they're something.

  5. If you use GPS Visualizer's Google Earth form (http://www.gpsvisualizer.com/map_input?form=googleearth) to create KML from your .gdb or .gpx file (rather than going straight from Mapsource to GE), the trackpoints will NOT be drawn by default. And if you do choose to have them (using the "Draw trackpoints as waypoints" feature), they will be small unobtrusive circles that are the same color as the track they belong to... NOT big white squares.

  6. I'm the owner of GPS Visualizer. Both my site and batchgeocode.com will find the coordinates of street addresses, but here's what I'd recommend:

     

    1) Go to batchgeocode.com and convert your addresses. It'll be slow -- 1-2 seconds per address -- but probably pretty accurate, because they use the Yahoo! Geocoding API for all addresses. (GPS Visualizer is faster but primarily uses a local copy of a Census Bureau database which is less accurate and less tolerant of funky input; also, GPS Visualizer will only do 400 at once.)

     

    2) Copy and paste the geocoded output from batchgeocode.com into GPS Visualizer's "convert" form: http://www.gpsvisualizer.com/convert?convert_output=gpx

     

    3) If you want, rename a couple of fields in your data to "name" and "desc"; or, just leave them be, and GPS Visualizer will probably build names and descriptions for you.

     

    3) Click the "Convert" button. Voila.

  7. [ I use GPS Visualizer to make a reliable .kml file from the .loc waypoint files you can download

    Another useful feature of GPSVisualizer.com: the ability to get alternate map/image overlays in Google Earth. See this page for details: http://www.gpsvisualizer.com/misc/kml_network_link.html

     

    For example, up on Mount Hood, I find that GE's fancy color satellite imagery is off by tens of meters; you can easily see that the shadows of ridges don't line up with the ridges themselves! But when I use the GPS Visualizer network link to bring in a USGS 1m aerial photo overlay, it's spot-on.

    Not as high-resolution as the more recent GE imagery, but far more accurate -- and it's been my experience that the USGS aerials are accurate almost everywhere.

     

    (For those of you in Canada, there are a few NRCan overlays available too.)

  8. If I need to find the coordinates of a point that I can easily locate on a map but which doesn't necessarily have an address -- like an intersection of two Nat'l Forest roads, or a stream crossing -- I use the Acme Mapper: http://mapper.acme.com/. It will try to locate addresses for you, and you can fine-tune the results by simply moving the Google map around.

     

    (The maps created by GPS Visualizer also have some Acme-like features these days: specifically, a crosshair in the center of the map with a readout of the crosshair's coordinates.)
