Project's objective

The main goal of this project was to create a topographic map and a 3D terrain model for the farm in Waco Kungo (Angola) in a short time.

Completed work

“Projects like Angolan will become the technological standard, both in terms of execution time and quality standards,” said Victor V. Lavrov, Deputy General Director at Innoter.

A 3D model of an agricultural farm on the territory of Angola, created in collaboration with Terra Space experts based on GeoEye-1 satellite imagery. A distinctive feature of the project was record-breaking work completion times: less than 1 month passed from ordering new surveys to finished maps and 3D models.
A set of works was performed:

  • planning and ordering a new space color survey from the GeoEye-1 satellite with a spatial resolution of 0.5m;
  • photogrammetric processing of the obtained images, orthorectification of images using the coefficients of rational functions of the camera (RPC-polynomials);
  • creation of a photo map and a digital topographic map in arbitrary conventional signs based on an orthorectification image;
  • creating a 3D farm model using the unique technology provided by Terra Space based on a single GeoEye-1 image and a topographic map created with an accuracy of 3 meters in height.
Orthorectification and radiometric correction was performed in the PCI Geomatica 10.2 program.
The mapping was carried out in the Mapinfo 10.0 program; decoding and drawing of point, linear and area objects were made.
Creating a 3D farm model using the Microstation V8 environment.

Results

The project was presented at the exhibition Geo-Siberia and aroused great interest from visitors. A distinctive feature of the project was record-breaking work completion times: less than 1 month passed from ordering new surveys to finished maps and 3D models.
