The Red River Basin relatively is flat and has low
relief, so the demand for high resolution data is in high. High resolution
topographic data is often
used in many different applications. It can be used in hydrologic models,
flood insurance studies, mapping, and other applications. There are many different
types of topographic data and at varying resolutions. This page is
designed to help locate and understand topographic data that has moderate to
excellent topographic resolution. Resolution is a loose term in data, in
general it means the level of accuracy. Topographic data that has spot
elevations every 2 feet has a higher resolution than data with spot elevations
every 10 feet. For more information on a specific type of topographic
data, please click on one of the topics. There is also a
presentation
by the U.S. Army Corps of Engineers that compares various methods for collecting topographic data.
There are also examples
of topographic data for the Red River Basin.
