7.5-Minute Topo. 7.5-Minute Topos closely resemble historical 7.5-minute USGS map products as well as US Topo maps.. This large-scale map type provides a high level of detail over approximately 50 to 70 square miles per map and can be used for recreation and navigation (orienteering and geocaching), city planning, search and rescue, science studies such as geologic and geographic field work ...
1. The Historical Topographic Map Collection (HTMC) is the set of scanned images of USGS topographic quadrangle maps originally published as paper documents in the period 1884-2006. Visit Historical Topographic Maps - Preserving the Past for more information. 2. US Topo is the current USGS topographic map series for the Nation.

In introductory geoscience courses, a profile is appropriate when you are asked to construct a cross-section. Topographic profiles are used to understand what a topographic map is telling you in a specific area (or, you can think about it as giving you a "side view" of the landscape along a specific line on the map). Interestingly, many geologists ...
Examine the topographic map image to the left (you can click on the image to make it larger, or you can download the map and a profile (Acrobat (PDF) 2.3MB Jul18 11) to try the steps below on your own). Before you start, you might want to review some of the rules about topographic maps (you can find rules at Idaho State U.'s field exercise, U. of M...
Topographic profiles are used in many applications in the geosciences. Some of the topics where you will need to recognize and draw a topographic profile are: 1. topographic maps 2. earthquakes 3. structural geology (and geologic cross-sections) 4. glacial geology 5. coastal geology 6. geomorphology
Several universities have tutorials on how to construct a topographic profile. Here are just a few: 1. University of Wisconsin, Stevens Point, has a flash animation to walk you through the construction of a profile. 2. Idaho State University has step-by-step instructions for constructing a topographic profile. 3. University of Texas at Austin has s...
Step 3: Create a Map From an Existing Map. Here is a general overview of the steps to follow: Open an existing map, the more recent the better. Save it as new in a different folder under the same root directory. Fetch the layers for your map (see next step) Style the layers (see step "Style layers")
