[Xastir] Off Topic: Method to deterrmine location of N minimum points from a dataset

[Brian Webster]

I use Manifold GIS (www.manifold.net) it has features call find nearest
service centers and such. You can see their help manual on line. Great video
training series for the software can be found at www.gisadvisor.com



Thank You,

Subject: [Xastir] Off Topic: Method to deterrmine location of N minimum
points from a dataset


Sorry for the off topic, but I am not sure where to start and I figured
some of you folks probably know..  Any suggestions on what I should
search on?

I want a method to calculate the locations of N points from a dataset of
locations that has a minimum cumulative distance.  That, what are the
locations of a given number of Basepoints so that the distance from the
dataset to one of he basepoints is minimized.   Specifically, if I have
a set of all the locations in a service area and I want to know where to
place service providers in the dataset, were should I put them if I have
two service providers, where should I put them if I have
three providers, etc.

I am sure I did this as a home work problem long ago in a computer
programming class, but I can't seem to come up with a simple means of
doing it.   I am betting the method is detailed out there somewhere, but
I can't find the correct search parameters.

Please send any suggestions to me at

Thanks all................ jt
