Stations are not allowed to have negative elevation about sea level
The following discussion from !1096 (merged) should be addressed:
-
@kerel-fs started a discussion: Stations might have negative elevation above the WGS84 ellipsoid (e.g. when placed around the dead sea)!
Migrate the Station.alt field from PositiveIntegerField
to IntegerField
. Consider to even allow sub-meter accuracy / non-integer values by using the FloatField
type. There is no physical reason why non-integer elevations should not allowed. The currently used propagation library is expecting integers, but the value can be rounded, allowing users to enter non-integer values (more intuitive).
