Finding the weighted center of some GPS Co-Ords

[Sockpuppet]

Hi Guys,

I have 300 GPS points on a map and a size for each one (sqft).

I have done the following:

((Max Lat - Min Lat) / 2 ) + Min Lat = Middle (done the same for Long)

(Middle - Lat) * sqft = value (this is neg if west of average and + for east of middle) - also done the same for

Then add all these up and divide by the total sqft allocated.

Add this to the Middle Co-Ords which pulls it in the direction that it wants becuase of the sqft.

Is there anything wrong with this method? This is just to prove / disprove a theory before I go for a full on CAST model which is going to take about a week.

2) delete your message #2 in this thread

3) I will delete my both messages

4) You will get responses to your question

Ha ha AtW.

Anyways, the answer is it that it looks OK, but my question is what are you trying to do? If you're trying to place a GPS tower then the land shape has an influence.
