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.
The USGS has announced a schedule for release of over 100,000 historic topographic map quadrangles covering 32 states by the end of 2011. This is an amazing resource for anyone interested in studying the history of an area in the United States.
Kansas is the first state in the release schedule [...]
The Geologic Map of North America was published in 2005 by John C. Reed, Jr. (USGS), John O. Wheeler (Geological Survey of Canada), and Brian E. Tucholke (Woods Hole Oceanographic Institution). This is an amazing piece of work that covers the entire continent of North America at a scale of 1:5,000,000. The map [...]
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 [...]
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 [...]
The National Elevation Dataset (NED) contains detailed elevation data for the United States and Territories. The NED comes in three different versions.
1 and 2 Arc-Second – This version has a resolution of approximately 30 meters (60 meters for Alaska) and covers all of the United States and Territories.
1/3 Arc-Second – [...]
Natural Resources Canada has created a digital topographic map for the entire country that can be viewed in Google Earth. The map is based on the WMS map service, which can be a little tricky to set up in Google Earth so I went ahead and set them all up. Just click on the [...]
