GEODETIC PROJECTONS
4.0 semester hours equivalent (non-transferable)
Recommended Prerequisite(s):
COORDINATE GEOMETRY

This course covers how to calculate control surveys utilizing map projections and state plane coordinates. Topics include geodetic-to-grid and grid-to-geodetic conversions for angles, distances and coordinates, with an emphasis on calculations in the Lambert Conformal Conic projection and comparisons to calculations in the Transverse Mercator and UTM projections. Upon successful completion of this course, students will be able to compute solutions to control surveys using state plane coordinates.
