Orthoregion

Since 2008 SOVZOND has been producing a line of exclusive orthorectified products under the name of ORTHOREGION - ORTHO10, ORTHO25, ORTHO50, ORTHOREGION + MONITORING.

Image orthorectification is performed by SOVZOND photogrammetric department. Separate orthorectified scenes are stitched into a single raster field with aligned tone, followed by cutting into sections, covering administrative areas or regions of the Russian Federation.

Rectified imagery from WorldView-1, WorldView-2 and GeoEye-1 satellites are the basis of ORTHO10. Orthorectification of separate scenes is performed by the method of RPC coefficients without using ground control points. The orthophoto mosaic scale is 1:10 000.

ORTHO25 is based on seamless orthorectified mosaics of ALOS / PRISM satellite images with a ground resolution of 2.5 m and an accuracy corresponding to the topographic map scale of 1:25 000. Orthorectification is carried out without the use of ground control points due to unprecedented precision RPC coefficients accompanying each shooting scene.

ORTHO50 is based on orthorectified images from RapidEye constellation. Orthorectification of separate scenes is performed by the method of RPC coefficients without using ground control points. The scale of orthophoto mosaics is 1:50 000.

ORTHOREGION + Monitoring is based on ALOS / PRISM imagery, but together with the basic mosaic a customer also receive a series of satellite images from RapidEye constellation, providing near-real-time monitoring of relevant areas.

The commercial success of the product is connected with the fact that it is tailored for end users:

  • Clients understand the order price and don’t pay for excess information (raw data, metadata, extra spectral channels);
  • Clients pay and get satellite image mosaic only for AOI (Federal District, state, administrative district, etc.);
  • Clients can, by passing intermediate stages, download it into usable GIS shell (for example, ArcGIS) and start to work.
