[mapserver-users] querying in mode=tile

[Rahkonen Jukka]

Hi,

If you happen to have a little bit time for considering some day, consider also using WFS for queries.  And if you cannot manage to get the geojson outputformat work through the OGR outputformat system in a minute, you can install TinyOWS besides Mapserver. It can read the same mapfiles and it can output geojson out-of-the-box.

> On second reading, I now get what you are saying. Strange that it never occurred to me. Sounds very sensible, and I will implement it tomorrow. That way I can get away from CGI `mode=query` and its TEMPLATE-ing vagaries. Yes, my data are in Pg, so I can do all my querying with Perl.
