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.

Best,

Edward

Subject: Re: [mapserver-users] data parameter in tileindex

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.
Sincerely, Zmitser

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.

Dear mapserver users, I need to specify data parameter at the location item of 
tileindex.
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.
