Geography

The next important aspect that must be considered about a potential building site is that of geography. In its most simple terms, this can be thought of as the roughness of the terrain. On important distinction must be made here. An area’s geography refers only to the earth itself, and not to what is growing on it. Thus, a barren arctic plain and a flat field in a temperate region both fall into the plains category. Later, when we discuss ground cover, you will see the forestation and vegetation of an area come into play. For now, though, think only about the rocks and soil.

As with climate type, an area’s geography will generate a PM that must be recorded for later use.
