Prevent same input value for min and max latitude / longitude value
hholzgra opened this issue · comments
Right now it seems to be possible to select the same value for minimum and maximum latitude or longitude, leading to a "division by zero" error during rendering later.
The form validator should either prevent such invalid input, or should extend the render area to a minimum of e.g. one arc second, or an absolute size of e.g. ten by ten meters.
