I order to find the best location of particular facilities the approach below is followed (please, have a look on the screenshot below). Here the software finds a specified number of facilities based on polygons and a certain field. For example, if the best locations of 10 clinics are required to be determine considering the size of smokers in each zone, then the analysis below can be applied.
Arc: w d:\n\results Arc: dir info Arc: ArcPlot ArcPlot: locatecandidates mm poly smokers_g ArcPlot: locatecriteria mindistance ArcPlot: locateallocate n1 n2 n3 10 ArcPlot: &stat 9999 ArcPlot: Shadetype color ArcPlot: mape mm ArcPlot: linecolor grey ArcPlot: polys mm ArcPlot: spider mm poly n1 mm# site1 2
The output (below) is a spider that represents the locations of the facilities
My issue here is that I couldn�??t find an equivalent tool in the ArcMap (advanced) that does this sort of work.
This shouldn�??t be confused with the �??location-allocation�?� command available in the Network Analyst. The �??locatecandidates, locatecriteria mindistance, locateallocate�?� commands derives new locations from polygons (based on a field) while �??location-allocation�?� of the Network Analyst derives new locations from the already existing ones.
