making route for intensive points with decimal coordiantes

Hi,

i am new on sas enterprise guide (7.11 version) so that reason my question sounds silly

i want to make routes for field teams for intensive points. I have data-set which includes decimal points at a city and i want to define 1km diameter-length fields which includes min 60 max 80 points. To make this i took the center point (decimal) of the city and try to calculate the distance (haversine formula) from center and later making group of them which 1km distance interval but i can not make it right. Have you any advice or how can i make the distance calculation?

By the way i am using computed columns to take this action not programming. Thank you in advance

Note: Geodist function does not exist in 7.11 version of SAS Enterprise Guide

You can calculate the distances without needing the geodist function. Take a look at: http://www.sascommunity.org/wiki/Driving_Distances_and_Drive_Times_using_SAS_and_Google_Maps

Then, I'd use proc modeclus to find the closest 60 or 80 points. Code is provided at: http://www.sas-programming.com/2013/05/finding-closest-pair-in-dataset-using.html

thank you for swift reply!

Now i must improve my coding technique on SAS 🙂

it s a bit hard for me because i m new on SAS Enterprise Guide
