Dems and Ortho‐Images from Aerial Photographs

Abstract

Digital photogrammetry has produced new products and brought automation to a number of traditional photogrammetric procedures. Some of the new products have been produced by the integration of data and information. With new products comes the need to assess their quality as this can have a direct effect on their potential use. Some of the new products and a number of parameters that affect their quality are discussed in this paper.
