Problem 1371. Altitude of locations on the earth

Dan, could you provide some more specifics here? Altitude in meters, feet, or furlongs? Against what reference? Number of significant digits you expect? Latitude and longitude are in decimal degrees? An example would also help.

Thank you for suggestions

I like test #7. Although doing it the "right" way, I seem to get decimal precision on the negative values which caused it to fail the test suite.

Fixed tests with negative values and rescored solutions!

This problem should probably be removed from Cody. The only way to find the required number is by registering at Google's platform with a credit card for a free trial (It has become like so since 2018). https://developers.google.com/maps/documentation/elevation/start
Other sites find the elevation given the same problem coordinates, but not with the same precision (1e0). The author should make the accuracy way more error-tolerant, 1e2, or delete the problem.

PS: For instance, Everest (27.988056°N 86.925278°E) 8840.0 m according to https://www.freemaptools.com/elevation-finder.htm, 8806.0 m according to https://www.maps.ie/coordinates.html, and 8518.0 m according to https://www.daftlogic.com/sandbox-google-maps-find-altitude.htm (which would require accepting precision of 5e2)

FYI: Everent is 8,848 m height. https://www.britannica.com/place/Mount-Everest/The-height-of-Everest

FYI: The mount Everest is 8,848 m height. https://www.britannica.com/place/Mount-Everest/The-height-of-Everest

Rafael S.T. Vieira brings up some good points. The tolerance has been updated to +/– 250 (500 total) so that the problem can be solved. Making the error window larger than that may be too generous, though.

Thanks, goc3, that made me hopeful, but there is still one problem. Cases #4 and #5 have depth data instead of elevation. And depth data is not available from any of the previously mentioned sites, and more: https://nationalmap.gov/epqs/, https://api.opentopodata.org/v1/eudem25m?locations=11,142, https://api.open-elevation.com/api/v1/lookup?locations=25,-90, https://developers.airmap.com/docs/elevation-api. I guess no one would imagine someone would be interested to know ocean depth. So to make this problem feasible without Google maps, it would still be necessary to remove cases #4 and #5, or to allow the use of the command if (to people that will use a site without depth data). Some people solved this problem using a creative form of lookup table without an if (cheaters). Therefore, this problem still needs some fixing...or to be deleted.

PS: I solved the problem using Google's API, and deleting my private-key afterward. If the test suite is changed, it won't work again (and all solutions really because they don't have keys or use lookup tables). Even if I didn't delete my private-key, it will only work for three months unless I pay a fee.
