Zmister, Check out the GH repo of the Amsterdam municipality. 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.

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. Sincerely, Zmitser Среда, 24 марта 2021, 6:53 +03:00 от Carlos Ruiz <[email protected]>: Zmitser, You have to have the following on a MAP file: LAYER ... CONNECTION "host=<HOST> ... password=<PASSWORD>" CONNECTIONTYPE <CONNECTION_TYPE> DATA "<GEOM_COLUMN> FROM <TABLE NAME> USING UNIQUE <ID> USING SRID=<SRID>" ... END On DATA you must specify the name of the geometry column and the table, if you're using a database. If you are using a shape file you just have to include the DATA keyword with the path and the name of the SHP file.

So far, I have tried many possibilities but none works: ‘host=127.0.0.1 dbname=database user=admin password=admin DATA "geom from table using unique id using srid=4326"’ or host=127.0.0.1 dbname=database user=admin password=admin data="geom from table using unique id using srid=4326" etc. Still I get an error : msDrawMap(): Image handling error. Failed to draw layer named 'layer'. msPostGISLayerOpen(): Query error. Nothing specified in DATA statement. Could someone please tell in which format data statement should be? In documentation it is written vaguely: Normally the location should contain the path to the tile file relative to the shapepath, not relative to the tileindex itself. If the DATA parameter contains a value then it is added to the end of the location. -- Zmitser Kozhukh _______________________________________________ mapserver-users mailing list [email protected]<//e.mail.ru/compose/?mailto=mailto%3amapserver%[email protected]> https://lists.osgeo.org/mailman/listinfo/mapserver-users -- Zmitser Kozhukh
