Hi,
I have a dataset like this:
Lat | Long |
51.39824 | -0.09366 |
51.52927 | -0.04583 |
51.54182 | 0.038004 |
51.41895 | -0.30561 |
51.59302 | -0.06998 |
51.60087 | -0.19474 |
51.55101 | -0.13727 |
51.50019 | -0.07006 |
51.48329 | -0.02586 |
I need to determine the minimum distance between these set of coordinates. I know about a function geodist() to determine distance between 2 coordinates, but not sure how to loop over through this set from the table.
Greatly appreciate your help.
Thanks!
You have to check distance between all unfortunately.
Use a Cartesian join in SQL and the GEODIST() function.
Heres a sketch of the code.
Proc SQL;
Create table dist as
Select a.*,
B.lat as lat2,
B.long as long2,
Geodist(....) as distance
From have as a
CROSS JOIN
have as b
Order by distance;
Quit;

Thanks a lot Reeza. It worked!
