Big Bend 24K Topos for Google Earth
« on: July 01, 2013, 05:27:53 PM »
Thought I would share some USGS seamless 24K topographic maps that I've converted into super-overlays for Google Earth. These are seamless in the sense that the map borders for each 24K USGS topo have been removed. The super-overlays will automatically increase in resolution as you zoom in, and the maps are geo-referenced to the underlying imagery in Google Earth. I also applied hill shading to the give the maps a more 3D appearance. They are yours to use, modify, and distribute however you like.


Preview of what it looks like in Google Earth

To install them, just click on the links below and download to a folder on your computer, call it 'Overlays' or something. Double-click on each file to open in Google Earth. Once open, right click on the file and click 'Save to My Places'. This essentially saves a link to the file on your hard drive so that the next time you open Google Earth it will still be there. What I usually do is save them to a folder in Google Earth called Overlays, and when I need to use them, I just check the box for that folder to view and un-check when I'm done. Note that if you zoom far out, the maps will disappear. This is by design and for the purpose of performance, meaning the topos won't be rendered when you're not viewing the area the overlay covers.

Great idea, Lance! :13:

But I can't see how to zoom in.
Wake me when it's time to go.

You have to have Google Earth installed then download the KMZ files with the links provided.  Open the KMZ files in Google Earth.
I just added the image in the post to show what it looked like.

Lsnead, thanks much for the "BiBe Google Earth Project.KMZ" (beta).

Perhaps I never noticed it before, as your salutation;    Or is that new?
Whichever, I have been iPad testing it for a couple hrs and it is awesome!!

Are all of those your tracks and spring IDs, or did others at BBChat contribute?

Great T/Rs and fotos too.  Thanks again, WetFeet.
well, You'll Have That...

I wanted to thank you also Lance.  I spent hours a couple nights ago looking over your map.  Nice work!!!

There's a dam on the Marufo Vega you don't have marked.
