Qgis measure distance along line
WebDistance analysis is fundamental to most GIS applications. In its simplest form, distance is a measure of how far away one thing is from another. A straight line is the shortest possible measure of the distance between two locations. However, there are other things to consider. Webfor i in xrange(0,count): # Get the random distance along the line. distance = random.uniform(0, length) # Work out the location of the point at that distance. point = geom.interpolate(distance) # Create the new feature.
