[mapserver-users] data parameter in tileindex

[Zmitser Kozhukh]

Thank you very much, Edward, for the suggestion. But I use tiles of vector data. And currently the problem is how to put postgis connection and data parameter in one (so that mapserver parses it correctly from location column of tileindex) .
With best regards, Zmitser

The MAP-file for 2020 is at  https://github.com/Amsterdam/mapserver/blob/master/lufo2020.map  where you can see the DATA connection to the Shape file that holds the tile index. The Shape files for the various years are in the folder  https://github.com/Amsterdam/mapserver/tree/master/luchtfoto . These were created using  gdaltindex  as you can see in the bash script at  https://github.com/Amsterdam/mapserver/blob/master/lufopyramids.sh . That's where you pass the location of the GeoTIFFs to populate the column in the Shape files so MapServer can open the required GeoTIFFs to generate an image  Hopefully these practical examples guide you.

>Dear Carlos, it is not about mapfile, it is in location cell of tileindex. It is one cell in table (database table, dbf file etc.), and I need to put there both connection and data details. The question is how to make it so that mapserver parses it correctly.
