We use PROC GEOCODE for some address geolocation, determining lat/long from address. I have noticed that the procedure is pretty inaccurate if you are not using the latest street lookup data.
I'm wondering when the "Prebuilt U.S. street lookup data for specific TIGER release" for SAS 9.4 will come out for 2017?
I've been checking this site:
http://support.sas.com/rnd/datavisualization/mapsonline/html/geocode.html
The Census Bureau normally releases new TIGER files in late August or September. It then requires a couple of weeks to process the files and post the lookup data to MapsOnline, so the 2017 files will not be available until the fall.
If your geocoding runs are not finding many matches, I'd like to ask that you contact SAS Tech Support. If they cannot find a reason for the non-matches, they will pull in the PROC GEOCODE developer. We'd like to know if your data uncovers a problem with the geocoder or the lookup data. Thanks.
I'm not sure what SAS' turn-around time is but they use the U.S. Census TIGER files which have not been released yet (I just checked their FTP site: ftp://ftp2.census.gov/geo/tiger/)

Thanks for the reply. I have compared 50 addresses with an alternative geocoding site and found there was minimal difference between the lat/long's. So far so good!
