G'day all,I am hoping to put lines (arrows) between polygons (to show flow). I was thinking of starting and ending the arrows based on the centroid of the polygon, but although I have found some stuff on doing this with PostGIS, I am using shapefiles and MSSQL Server, so my question is :
Can I find or calculate the centroid of a shapefile (ideally from php/ mapscript)?
