Hi,
I remember a french made plugin made for heath sciences that had that option to
fuzz data position within a certain radius. I can't look now because of
my internet connection. I you can't find it, I can check tomorrow if you hail
me. Look in mmqgis plugin, there could be something there also.
Hope this help
Nicolas

I would like to perturb all the point locations on a layer by a random
amount within a range, from say 100 feet to 500 feet. Each point should be
individually perturbed with different values for the x and y, but the overall
perturbation range will be the same for the layer. The purpose is to
obfuscate actual locations in a data set. I have not been able to locate
anything that will do this. I can use the Update All capabilities on the
attribute table to get values for an attribute, e.g. attribute_x =
$x+randf(100.0,500.0) but I am not clear on how to push this back to the
actual x coordinate of the point. Any suggestions, including python scripting,
plugins, or other approaches, will be welcome. Thanks in advance. Dick Males
