Comparative Analysis of Some 2-D Transformation Models for Third Order Accuracy Planimetric Mapping.

Abstract

Considering the ease and speed of planimetric mapping from aerial photographs, transformation of resulting image-space vector of co-ordinates into real-time object space co-ordinates becomes an essential engineering problem for photogrammetric evaluation. A careful evaluation of three (3) different 2-Dimention co-ordinate transformation models is herein presented. The similarity model showed least suitability while the polynomial model proved maximally effective for thirdorder accuracy planimetric mapping.
