Spheroid projection

WebMay 30, 2024 · Because the Earth is curved and in GIS we deal with flat map projections, we need to accommodate both the curved and flat views of the world. In surveying and geodesy, we accurately define these properties with geodetic datums. We begin modeling the Earth with a sphere or ellipsoid. WebGeographic coordinate systems use a spheroid to calculate positions on the earth. A datum defines the position of the spheroid relative to the center of the earth. ... ArcInfo 8.1 and ArcView 8.1 are designed to recognize, interpret, and correct for spheroid, datum, and projection differences. Traditional ArcView GIS 3.x and ArcInfo 7.x ...
