Cadastral Mapping (18 hours) This unit covers the land identification systems (metes and bounds, rectangular survey and coordinate) commonly used in Oklahoma. Also covered are parcel identification systems (sequential numbering, geocode, map based) used to assign each tract of land in Oklahoma a unique number. This program goes into ownership data gathering, map sources, mapping equipment, base maps, conveyances, acreage calculation, and mapping administration. A comprehensive case problem allows application of principles learned in the class.
