Assessing Geometric Accuracy of Ortho-imagery Subtitle: towards Product Specification of Fully Orthorectified Imagery for Urban Areas

Artefacts such as leaning of buildings result from the processing of traditional orthorectified imagery, limiting their use in urban areas. Orthophoto production was usually limited to medium and small-scale applications: typically smaller than 1:10,000. Even in the 1990s, this market was so under-developed that line map restitution from stereo imagery was cheaper than producing large-scale orthophotos. With the arrival of digital sensors, which have a high degree of overlap and higher cost efficiency, fully orthorectified products have entered the market. The authors test the positional accuracy of fully orthorectified imagery for urban areas and suggest a product specification.
