Abstract

A digital orthophoto can be obtained by rectifying a digitized perspective aerial photo. The orthorectification requires a terrain elevation model to remove the displacement caused by terrain relief. This paper describes a technique for partitioning a large photo into multiple subimages, mapping them onto the array processor for rectifications, and combining the results into an orthophoto. The combination of innovative algorithms and the massively parallel processor architecture leads to a significant improvement in throughput of digital orthophoto production.
