Students, using tools available in LPS, work through the process of creating orthos from commercial satellite imagery. Using a variety of sensor models a photogrammetric workflow is followed: creating a blockfile; adding RPC information; collecting ground control; RPC refinement; creating orthos or orthomosaics. Following the creation of an output students learn how to check and analyze the accuracy of their final product. (2 day class)
