thanks so much for this great tutorial!

i’m trying to run Andy’s query and I’m getting some strange behavior:

SELECT ID, NAME, CONTAINS( ogc_geom, GeomFromText(‘POINT(15 60)’) ) AS C
FROM `world_boundaries` WHERE CONTAINS( ogc_geom, GeomFromText(‘POINT(15, 60)’) ) = 1;

returns Norway, Russia, Sweden, and the US. i’m very confused by this. can you explain this behavior? (there are many similar queries for which i get multiple results)

thanks,
vishay

This is a well written article, Thanks!
However, I have had problems and wondered if you were aware of any issues with some of the polygons? e.g. After importing the sql file, and running this query:
SELECT ID, NAME, CONTAINS( ogc_geom, GeomFromText('POINT(60 15)') ) AS C FROM `world_boundaries` WHERE CONTAINS( ogc_geom, GeomFromText('POINT(60 15)') ) = 1
It only returns United States Minor Outlying Islands. 60,15 is well within Sweden.
Any suggestions would be helpful!

By the way, a new version of world_borders has been added: TM_WORLD_BORDERS-0.3.zip

It includes regions, which I am interested in. I’ll look into it and post it here if it requieres of any change.

I zipped the file using the archiving utility on my MacBook. The file unzips correctly on both Mac and Linux. It should be the same with WinZip…

I get an “unrecoverable zip file read error” from Winzip when I try to open the SQL dump zipfile. I tried a few downloads … do I need a different unzip tool, or can you re-post it?

Thanks in advance
