Sekundarni naslov: | Time series analysis of satellite images from different sources |
Sekundarni povzetek: | Combining the images obtained from different satellite systems we have the possibility of obtaining data points with greater temporal resolution. This presents us with a challange of combining satellite images that are somewhat different in their values. In our master thesis we describes the process of combining two sources of high-resolution satellite images % Sentinel-2 and PlanetScope. We produced NDVI rasters and harmonized them using linear regression trend line parameters obtained from scatter plots of PlanetScope and Sentinel-2 NDVI rasters. With those parameters we altered the values of PlanetScope NDVI rasters to make them more in line with values of Sentinel-2 NDVI rasters. We showed that there was a noticeable improvement between values of un-harmonized input and harmonized output PlanetScope data in comparison to the NDVI values of the referenced Sentinel-2 data. We used the parameters we obtained in the harmonization process to make combined time series from PlanetScope and Sentinel-2 data on different areas of land use that we obtained from GERK. We automated the whole process using Python and PL/pgSQL. |
