st: Latitude, Longitude and distances
Dear statalist users,
My problem is the following:
(and I am sending it again to the statlist since the follow-ups to my
initial email were not follow-ups to my question)
I have a dataset that has 3 variables: location_id, latitude, longitude.
I would like to calculate the distances between the locations but I'm not
sure of what is the best way of storing this information in Stata. Suppose
we have 30 locations (i.e. 30 observations).
Any ideas on how to to calculate the distances and, more importantly, on how
to store them (in an effective way, for future manipulation)?
Thanks for your help!
