This link: https://i.redd.it/gm8273jvjrk71.jpg https://i.redd.it/gm8273jvjrk71.jpg is an map (outdated though, it dates to 2019 AFAIK) of how much of the Earth's surface has been mapped by google street view.
Is there a similar map product that shows how much of the Earth's surface has yet to be surveyed with lidar (or a suitable equivalent)? I would assume that areas with zero vegetation can be covered by satellite imagery but it is possible that the resolution is poor (for example, SRTM had a 30m resolution).
- ipdashc 2y agoThat map, while interesting, seems entirely subjective - the whole appearance of the map can be determined by the thickness that you set the street view lines to, no?
- bee_rider 2y agoI guess you just lose the ability to distinguish between areas past some density, right? What would be a good way to improve it… maybe apply some filter, Lanzcos or whatever?
- AlotOfReading 2y agoThe technical term is "viewshed analysis", what areas are visible from a given set of points. Any competent GIS system will have ways to do it, but peakfinder.com works pretty well as a more visually interesting demo.
- perihelions 2y agoThat doesn't appear to be the same problem?
- AlotOfReading 2y agoGuess I didn't read the parent closely enough. Thought it was asking what the best way to figure out the actual coverage without arbitrarily increasing line width as you zoom out.
