Seamless Topographic Maps for Google Earth

I have had many requests over the years to add a USGS topographic Map overlay without the map borders. This is a huge project and I have finally decided to move forward with it.

You can read more about this project below, or skip right to the store and purchase them.

SRTM Enhanced Blue Marble Terrain Map of California

This terrain map of California was created by combining the NASA Blue Marble imagery with the global elevation data from the Space Shuttle Radar Topography Mission (SRTM). The combination of these two data sets creates an amazing new way of viewing the Earth’s topography and landforms.

The SRTM elevation data is detailed enough [...]

Washington DC Historic Maps

This is a collection of historic maps and birds eye images of Washington DC during the late 1800s and early 1900s. The collection includes 58 highly-detailed topographic maps that appear to have been completed in the 1870s and 1880s of the outlying areas of Washington DC. These were a bit tricky to georeference, but [...]
