Too many vertices #1

Open mc-langdon opened 1 year ago

mc-langdon commented 1 year ago

There is a limit to the URL path for the GET request that provides the vertice co-ordinates to the defra ESRI portal. This means that there is a limit on the number of vertices.

Potential solutions could be:

simplify the polygon - avoids downloading superfluous tiles.
just use the extents of the polygon - could download tiles that are not needed.

Testing has revealed that the vertex limit is 33 vertices in a polygon. I could increase this number if there is a way to reduce the accuracy of the co-ordinates (currently 11d.p. being used!).
