## Technology Part
### Data origins
**Sentinel-2** (2 satellites) is an optical mission with a multi-spectral instrument mainly for agricultural applications such as crop monitoring and management, vegetation and forest monitoring (e.g. leaf area index, chlorophyll concentration, carbon mass estimations), monitoring land cover change for environmental monitoring, observation of coastal zones (marine environmental monitoring, coastal zone mapping), inland water monitoring, glacier monitoring, ice extent and snow cover mapping.
### Data acquisition
At [Scihub](https://scihub.copernicus.eu/dhus/) we used query for Vienna
```
platformname:Sentinel-2 footprint:"intersects(48.2082,16.3738)"
```
to get proper file names of data from Sentinel 2, which we unziped and loaded into qGIS
### Data processing
[Convert Landsat DNs to albedo](http://yceo.yale.edu/how-convert-landsat-dns-albedo)
i.e. use this formula can be implemented in ENVI using Band Math as:
```
((0.356*B1) + (0.130*B2) + (0.373*B3) + (0.085*B4) + (0.072*B5) -0.018) / 1.016
```
We know that calculation of Albedo is hard thing in this industry
