Main application of the WorldView-2 satellite imagery:
- Creation and update of topographic maps and plans of scales up to 1:5000;
- Creation of DTMs;
- Engineering survey for construction works of oil and gas facilities;
- Inventory of forests and forest management;
- Monitoring of the crops’ state, yield forecasting;
- Creation of maps for urban planning purposes;
- Emergency monitoring;
- Researches.
