I work in remote sensing and we do e.g. segmentation of satellite imagery. There are two exciting developments: First, lots of vector data (think building footprints, road networks, etc.) and (satellite) raster data (e.g. Sentinel-2) is now available for free, secondly image segmentation using CNNs works just extremely well. Therefore there are many opportunities to build all kinds of software, in particular CNN based classifiers and distributed systems to handle the immense load of new data.
So I can highly recommend the field of remote sensing as there are many interesting problems to solve.
- consultutah 10y agoWhere can you get satellite derived building footprints for free?
- zeptomu 10y agoThere is currently no established hub, that aggregates them, but public agencies often offer them on some open-data initiatives on a national level, e.g. Austria has https://www.data.gv.at/ https://www.data.gv.at/ and searching for "Gebäude" (building in German) lets you find e.g. the data set https://www.data.gv.at/katalog/dataset/ac74b38e-57cd-4c8c-8fea-c397da185fcf https://www.data.gv.at/katalog/dataset/ac74b38e-57cd-4c8c-8f... where you can download building footprints for the state of Tyrol. The same thing is also done on an international level, e.g. the European Union provides platforms and also the environmental agencies in the US. # edit: Clarification: These footprints are not satellite-derived (that is the goal, but it doesn't work well enough for many applications, but we probably will get there ...), but are hand-crafted by people working in city planning. The point is you can use the data as training data.
