Possible Workflows

PHOTOMOD is a system designed to provide full photogrammetric processing of aerial and spaceborne images. The most typical tasks in the photogrammetric processing of remote sensing data:

  • Creation of digital terrain models (DTMs) and contour lines
  • Digital 2D and 3D mapping
  • Orthorectification and mosaicking

Processing workflows for different types of input data and output products are variations of the general workflow.

Depending on source imagery PHOTOMOD projects are subdivided into the following types, each having a number of specific features:

Several projects of the same type are also capable of being merged to work with large blocks of images.
