Mine is mapping. I am a big OpenStreetMap contributor and I have mapped many towns near me that were previously completely unmapped.

    You use aerial imagery and trace the buildings, roads, and other features using points on a grid.

      I watched the video you linked. So it’s enhancing existing maps - I was thinking it was building the maps themselves from scratch. A long time ago I worked with a small company that created digital street maps for cities to use for utility work etc.

        It can be making maps from scratch. There are a lot of places where the map has no features, mostly rural areas.

      Is that your own imagery, from drone footage for example, or are you basically copying Google Earth?

        It’s from Bing and Esri. It’s not copying anything, as aerial imagery is a different thing than a map. Also Bing and Esri imagery is specifically allowed to be used for OpenStreetMap purposes, likely because companies benefit from OSM data.
