Lmao, lasers and demons shooting colored rays.

Something bugging you today?

Why even come here if your just going to parrot the mainstream.

And I had to look this up, because I didnt think there was no way in hell that google has laser measurements of all elevations.

https://en.wikipedia.org/wiki/Shuttle_Radar_Topography_Mission

The elevation models are arranged into tiles, each covering one degree of latitude and one degree of longitude, named according to their south western corners. For example, "n45e006" stretches from 45°N 6°E to 46°N 7°E and "s45w006" from 45°S 6°W to 44°S 5°W. The resolution of the raw data is one arcsecond (30 m along the equator) and coverage includes Africa, Europe, North America, South America, Asia, and Australia.[3] A derived one arcsecond dataset with trees and other non-terrain features removed covering Australia was made available in November 2011; the raw data are restricted for government use.[4] For the rest of the world, only three arcsecond (90 m along the equator) data are available.[2]: 4821  Each one arcsecond tile has 3,601 rows, each consisting of 3,601 16 bit bigendian cells. The dimensions of the three arcsecond tiles are 1201 x 1201. The original SRTM elevations were calculated relative to the WGS84 ellipsoid and then the EGM96 geoid separation values were added to convert to heights relative to the geoid for all the released products.[5]

The elevation datasets are affected by mountain and desert no-data areas. These amount to no more than 0.2% of the total area surveyed,[11] but can be a problem in areas of very high relief. They affect all summits over 8,000 meters, most summits over 7,000 meters, many Alpine and similar summits and ridges, and many gorges and canyons. There are some SRTM data sources which have filled these data voids, but some of these have used only interpolation from surrounding data, and may therefore be very inaccurate. If the voids are large, or completely cover summit or ridge areas, no interpolation algorithms will give satisfactory results.

So most of its from lasers, but not all of it, and its all second hand information.

Just so you know.

No demon shooting rays required. And yes I know your being sarcastic, but you sound as dumb as me when im bitching about being poisoned.
