One issue with a lot of the free aerial satellite maps that exists is the actuality of the acquired images in terms of the acquisition date. A lot of times the images are a few years old and will not represent the current reality. This project will try and mitigate this by using free open data from the Copernicus directive supplied by the European Space Agency ESA and use that to create maps. By doing this the ability to have daily updated aerial satellite maps occurs and that could be really interesting for scientific and commercial purposes. To make this work an automated process was created that downloaded the images from Copernicus and processed them with GDAL to create the maps. The process deals with the issues of mosaicing, reprojection and unattended downloads amongst other things. In the results, there is a comparison between three different maps to give a comparison and an idea of how big of a map the process can handle in a reasonable time.
