We have an extensive collection of United States Geological Survey 7.5 Minute Topographic Series (1:24,000 scale). We also have topographic maps at 1:50,000, 1:100,000, and 1:250,000 scale for many parts of the United States. Our topographic maps cover various years. The USGS officially completed the 7.5-minute map series in 1992, and has replaced the print program with The National Map. Topographic maps from the 7.5-minute program, as well as various derived products, are available to view and download at the USGS store. The collection also includes some topographic maps from regions around the world.
We hold the copies of the Texas county soil surveys published by the Department of Agriculture. Most are also available online, http://soils.usda.gov/survey/printed_surveys/
Flood Insurance Rate Maps from FEMA
These include Texas communities that are in the Flood Insurance Program. Some are available online through the FEMA Flood Map Service Portal.
Outline maps of the world and US can be found at About.com.
The collection contains geologic maps of the United States and Texas. A wide range of geologic maps can also be found at the USGS National Geologic Map Database.
The library contains the complete set of the Geologic Atlas of Texas in paper. The digital version was created by the Texas Water Development Board, Groundwater Resources Division.
We have few original and reproductions of historic maps. You may view historic maps online at the Library of Congress’ American Memory and at the David Rumsey Collection. Maps from the US Serial Set (from 1789-present) can be found through our subscription to ProQuest Congressional database.
We collect the following government produced series: TPC (Tactical Pilotage Charts); ONC (Operational Navigational Charts); GNC (Global Navigational Charts) and Sectional Aeronautical Charts. We also have a number of world nautical charts and celestial charts. Digital version of NOAA's Nautical charts can be found on their On-Line Chart Viewer.
