The most current map of each area is available from The National Map. TopoView shows the many and varied older maps of each area, and so is especially useful for historical purposes—for example, the names of some natural and cultural features have changed over time, and the historical names can be found on many of these topographic maps. Geological maps. One powerful representation of the geometry of rock structures is a geological, or geologic map. Geological maps are created through the process of mapping in which outcrops are visited in the course of fieldwork, described, and recorded on a topographic base map. The result is an outcrop map in which the …Thematic Maps of Texas. Click map to enlarge.
