I'm sure this has been addressed in detail in the past, but I've never confronted this problem before and I can't find a reasonably simple solution using MB. The situation is: I have some points that were geocoded to zip centroids because they wouldn't geocode to addresses. In some cases there are over 100 objects at the same zip code centroid coordinate. The objective is: I want to disperse them around the zip code polygon in which they occur so they'll approximate the dispersion of the accurately (to street address) geocoded points and stay within the polygon. (The cooler objective would be: I would like to get fancy and disperse them "proportionately," that is by some calculation of the relative densities of points throughout the zip code area, but right now my objective is more limited.) The problem is: I have written an MB utility that randomly disperses the points within the MBR. The problem with the MBR is lot of irregular polygons do not have much to do with the MBR except that it describes a rectangle with max and min x and y. I get results where about half of the points dispersed fall within the polygon; the other half are elsewhere in the MBR. I'd like the points to fall in the polygon, not in its MBR. BTW, I've used the point dispersion utility, but don't like the results very much. Are there solutions to getting points in polygons by identifying where the polygon is and plunking the points down in and not out?
