Can Stata help with submarket classification based on geographical coordination system?

[Melanie Zhang]

Hi Statalists!

I was wondering if Stata can classify observations into sub markets based on geographical coordination system (latitude&longitude). I have got a dataset with latitude and longitude of each observations, on which I need to apply a market cluster definition. Supposing I could get the territories of each sub market, can I match them with the data via Stata? Which code/program should I adopt?

I had tried a simpler method of -merge- to merge observations with the submarkets based on zip codes, but unfortunately some of the submarket categories does not match the zip code system, hence the matching gets messy result... so I would appreciate a lot if anyone can kindly give any suggestion on that!

Kind Regards,

Mel

If I got you right you want to match some geographic locations into terititorial areas?
If you have a shapefile of those territories look at -geoinpoly- . --> https://ideas.repec.org/c/boc/bocode/s458016.html
