    Default GPS Visualizer Overlays discussion

    This is a discussion thread for the following file:

    GPS Visualizer Overlays

    As posted on the GPS Visualizer website:

    "This page will help you create alternate overlays for use with Google Earth. It's true that Google Earth already contains high-resolution satellite data for many cities (and even some non-urban areas); but in much of the U.S., the USGS black-and-white 1m aerial photos provide better detail, and the USGS topo maps contain information which is not available in GE in any form. For the rest of the world, pictures from the "Terra" and "Aqua" satellites might be of interest, if your data covers a large area; they transmit up-to-date (but low-resolution) images back to earth every day.



    If you try to generate an overlay and get an error about the map server being unavailable: my sincere apologies, but it's out of my control. TerraServer-USA.com sometimes goes down for hours or days at a time, and the USGS data is simply unavailable when that happens."

    This is a great post. I approved it after doing a KML overlay for Prescott AZ. It fit perfectly.

    My mind works better in sentences with spaces and long paragraphs loose me sometimes cause I need to picture what is going on at the same time I am reading.

    The original page on GPSVisualizer.com, with more info and at least one example: http://www.gpsvisualizer.com/misc/kml_network_link.html

    (Eventually I'm going to add a few more examples of places that look much better with a little help from Landsat or the USGS; e.g., Krakatau.)
