Hello all
I have about 4500 spatial points which are irregularly spaced...
What is want to do is to replace points that are clustered very near
each other by one point ...i.e say the distance betweeen Point A Point B
is less than a threshold that i will define , i will delete either A or B
Sandeep,
I had a similar problem when I worked with wildlife GPS data and cluster
analysis, and I had over 50,000 points.
What I essentially did was... create a distance table for all points
(4500x4500 in your case)
Every row represents a spatial point and every column represents every other
