General Discussion / New KMZ Map Source
December 05, 2012, 10:01:26 AM
Hi All -

I'm the creator of the mapping website caltopo.com.  I just launched a new feature that allows you to easily generate .kmz files of my map layers (topo, forest service and aerial imagery, among others), and I'm looking for help testing it.  As a disclaimer this will eventually be a paid feature, but it's free for at least the next month while I work any bugs out.  You get free KMZ maps and I get some testing, hopefully.  All I ask is 1) please contact me with any issues so that I can fix them and 2) please don't abuse my server by stockpiling hundreds of large KMZs.  I don't yet know how the load from this will impact the rest of my site, as it all runs off the same server.

Instructions are at caltopo.blogspot.com/2012/12/garmin-custom-maps.html, or you can go directly to caltopo.com/kmz.html (forum software prevents me from making them links).  You can combine multiple layers using the +0 in the top right, to get things like relief shading and contour lines on aerial imagery.

In order to make the most of Garmin's 100 image restriction, the service combines 16 standard 256 pixel web map tiles into a single 1024x1024 image.  The selection tool moves in increments of 1 image / 4 web tiles at a time, which is why it's a little jerky.
