Elevation data production
Satellites provide capabilities for production of valuable elevation information for areas with no direct access which is needed during aerial data acquisitions. The project will evaluate applicability of elevation models derived on the base of various satellite data for particular areas of interest, validated and complemented with information about technical and operational limitations, quality assessment and quality–to-price ratios in reference to the aerial datasets being currently in use (ALS). Provision of the following data and documentation is planned:
- Dataset 1. Elevation data based on Pleiades stereo-pair on tri-stereo bundle composed of classified point cloud, raster DSM, raster DTM, operational report, quality assessment report, quality-to-price report.
- Dataset 2. Elevation data based on interferometric analysis of pairs of Sentinel-1A/B data composed of raster DSM, raster DTM, operational report, quality assessment rapport, quality-to-price report.
