Sentinel-2 Data for UAV flights planning

Satellite imagery is one of the basic components for planning UAV (unmanned aerial vehicles) flights. Therefore it is no surprise that Sentinel-2 data is increasingly considered as a reliable source for more accurate planning in areas, where up-to-date data are required (e.g. open-pit mining, agriculture areas, developing areas, etc.). A German company MAVinci GmbH, recently acquired by Intel, is the first using Sentinel Hub for planning their UAV flights.

Most UAV providers base their mapping software on Google Maps, Bing or similar imagery, which is widely available and in some areas (especially urban) very detailed. However, using such systems in practice often shows that the imagery is outdated. Generally such data are updated once or twice per year in urban areas. Rural areas have often imagery several years old. This is often not sufficient for UAV tasking. Sentinel-2 data with revisit time of 10 days (or even less in higher Northern and Southern latitudes) is an ideal source. The resolution (10 meters for RGB and NIR bands) is not as good as for some commercial imagery, but being able to get extremely recent images outweighs this fact. Having multi-spectral data on disposal helps as well, especially in agriculture and geology fields.

Sentinel Hub, with its WMS and WMTS web service options, provides a perfect solution for UAV providers as they can integrate it in a matter of minutes. They immediately have global coverage of data available with archival images, cloud coverage filtering and similar features.
