Abstract
When using analog aerial cameras, photomaps were assembled from transformed images. If the elevation of the points of the terrain made it possible to obtain acceptable distortions for the relief, then they were transformed into one zone. Otherwise, the transformation was performed by zones, allowing displacements in each zone of no more than 0.4 mm. In neighboring zones, the displacements at the zone boundary had opposite directions, and the discrepancy between the contours could reach 0.8 mm. Its average value was taken as the final position of the contour, which compensated for position errors in neighboring zones.
When creating digital photomaps and orthophotomaps, digital elevation models (DEM) are used to account for terrain distortions. Digital transform technology does not use transform zones and therefore will not compensate for errors as it would with zone transforms. The quality of the orthomosaic will depend on the accuracy of the DEM. A digital model of a relief or surface has a high density and makes it possible to take into account distortions for the relief much more accurately than when transforming by zones.
The paper analyzes the requirements of the current regulatory documents when creating digital photomaps and orthophotomaps, provides relevant conclusions and recommendations.
