As far as I know there is no length function in Mapserver. The only geometry function to use in Expressions is area(shape). OGR sql doesn’t provide that either as far as I can see in the documentation.
So the solutions might be to convert your KML data to sqlite or postgis where such functions are available. The length of a string (number of characters in the string) can be found in OGR sql with the length function, but I am assuming You are looking for the geometric length of the linestring. /Lars From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of alok mathur Sent: den 13 mars 2015 07:01 To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] Calculate length!
