[postgis-devel] filter by m-value and effective area

[Nicklas Avén]

Hello

Sorry for the delay. 

I have put what I have at :
https://github.com/nicklasaven/postgis/tree/filterm


It is just a start. It should work for linestrings and polygons.
collection logic is not in place.

No doc and no tests yet.

New function is 

ST_FilterByM(geometry, double precision)
