[Qgis-user] perturb point locations

[Nicolas Cadieux]

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

	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 Cincinnati, OH USA
