SANBORN TRUE ORTHO OPTION

What Are True Orthos?

While standard orthophoto rectification corrects relief displacement in ground level features, above ground features, such as the tops of buildings and bridges, aren’t normally corrected because they are not modeled in the digital terrain model (DTM). In the final orthophoto, these features appear distorted in the form of building lean and warped bridges. In severe cases, the distortion can impact the usefulness of the imagery as many ground features may be obscured. With the True Orthophotography Option, streets and other features surrounding buildings are clearly visible. Employing innovative Sanborn proprietary software and procedures to create True Orthos, more cadastral information can be captured from digital orthoimagery.
