Photogrammetry

Catalog description

SUR 222 covers the basic principles of aerial photography and the geometry of the optics in relation to aerial cameras. Mathematical theories for refining and processing measurements from single aerial photographs are developed. Such measurements are transformed to obtain real world coordinates of features on the surface of the earth. Two and three-dimensional coordinate transformation equations are developed and applied to the measurements on the photographs. In addition, the theory underlying the geometry of stereopairs of photographs is developed and used to determine three-dimensional position on the surface. Stereographic equipment and software are used to produce photogrammetric point clouds, accurate topographic maps of the overlap areas using an aerial image block, and orthophotos. An introduction to Unmanned Aerial Systems (UASs) and their usage for topographic surveying are presented. The course also covers procedures and considerations for planning an aerial photography mission which includes flight planning, cost analysis, equipment selection, ground controls points configuration, and overall photogrammetric project management. Mapping using aerial photogrammetric data and using standard industry software such as CAD and GIS.
