Paper Abstract

The acreage of a land parcel is the area of the parcel's coverage on the geodetic ellipsoid surface. There are two methods to compute the land parcel acreage from its area in the map projection coordinate system. The first method is to compute the acreage of an administrative zone, then use the acreage of the administrative zone to control the acreages of the land parcels within it. The second is to compute the acreage of a map sheet first, and then use the acreage of the map sheet to control the acreages of the parcels within that map sheet. There are three methods to calculate the slope grade of land parcels, each has advantages and disadvantages. They should be used under careful consideration of the specific situation.
