Administration of the city district of Revda

Project's objective

Update topographic plans of the territory of the city district Revda

Completed work

1. Aerial photography works with a pixel projection size on the ground of not more than 0.10 m. Aerial photography was performed in the RGB spectral range, in frame shooting mode, with a longitudinal overlap between aerial photographs of 70-80%, with a transverse overlap of 50-60% of the equipment capture width on the ground. With the definition of the coordinates of photographing centers using GPS / GLONASS satellite positioning technology by a differential method.

2. Creating a stereophotogrammetric model of a scale of 1: 500 with a height of the cross section of the relief after 1.0 m.

3. The creation of digital orthophotomaps of 1: 2000 scale included the following processes:

  • creation of a digital terrain model by the stereophotogrammetric method in PHOTOSCAN software with a step of 0.2 m;
  • creating stitching lines;

  • orthorectification of aerial photographs;

  • cutting orthophotomaps on nomenclature sheets.

In total, 189 digital orthophotomaps were created.
