Is there a 'friendly' way to create dot-density maps, where a polygon attribute data defines the number of dots (e.g. 1 dot = 100 ) using QGIS 1.7+? I say friendly because after a couple of hours researching all the alternatives seem to require programming. Maybe I am not looking in the right place. I am already aware of the fTools 'Random Points' feature and it is not what I am looking for.
That is precisely what I am seeking. However every time I attempted to run this function. I received the following:
An error has occured while executing Python code: Traceback (most recent call last): File "/usr/share/qgis/python/plugins/fTools/tools/doRandPoints.py", line 118, in accept self.randomize(inLayer, outPath, minimum, design, value) File "/usr/share/qgis/python/plugins/fTools/tools/doRandPoints.py", line 210, in randomize else: points = self.loopThruPolygons(inLayer, value, design) File "/usr/share/qgis/python/plugins/fTools/tools/doRandPoints.py", line 256, in loopThruPolygons sExt = sGeom.boundingBox() AttributeError: 'NoneType' object has no attribute 'boundingBox' Python version: 2.7.1+ (r271:86832, Apr 11 2011, 18:37:12) [GCC 4.5.2] QGIS version: 1.8.0-Trunk Trunk, exported
If this result created using "Random points" is not what you are looking for, you'll have to be more specific about your requirements.
