Allow user to fix too large areas

[rpulkka]

Use cases:

A) Person uses Mobiliivihko for tracking a trip (e.g. by car) that covers a large area
B) GPS gives incorrect information, making the geometry too large

Both of cause that the user is not able to submit their document to Vihko, since the API gives an error "Too big area. Maximum is 1000000 hectares".

The user cannot fix this by any means, since Mobiilivihko cannot be used to edit the geometry.

Options:

Automatically stop route if it's too long (e.g. 50 km?)
Allow user to change geometry on Mobilivihko. How? Replace location with centerpoint?
In case of this problem, don't use the route, but observations bounding box instead.
Remove area restriction from API
