Does anyone know why isn’t it possible to get the same perspective (preserving scale, distances, areas) in Google Earth Web?
For example, you wouldn’t be able to get the shapes of continents along with the size of the whole globe in Google Earth visually match the projection under “line” example in README.

- dsl 9y agoThere are lots of different map projections[1] and coordinate systems[2]. As the old joke goes, "the best thing about standards is there are so many to choose from!" 1. https://en.wikipedia.org/wiki/Map_projection https://en.wikipedia.org/wiki/Map_projection 2. https://en.wikipedia.org/wiki/Geographic_coordinate_system https://en.wikipedia.org/wiki/Geographic_coordinate_system
- goblin89 9y agoIf you want to map whole planet’s surface onto a plane then sure, there’re tons of options (Dymaxion projection is my favorite). I can’t understand why areas and distances would be distorted if user manipulates a 3D globe though; yet it seems to be the case here.
- dsl 9y agoThat is exactly the problem. It is easy for programmers to start with a 3D sphere and start randomly projecting things on to it. However the earth itself is an ellipsoid that bulges around the equator, so again you have a projection problem of people trying to put one shape onto a different shape.
