[mapserver-users] combine many georeferenced tifs in one layer

[Janosch.Skrobek at trier.de]

Thanks a lot Bart and you too Till!

I had some troubles with the wildcards (*.tif) since the gdaltindex binary from gdal.org doesn't seem to support them - although it says so in the manual. I googled a bit and found fwtools which have gdaltindex implemented as well and here the wildcards work. 

But just as I thought I get follow-up problems :)
1) gdaltindex puts out a warning when processing my tiffs:
Warning 1:TIFFFetNormalTag:ASCII value for tag "copyright" contains null byte in value; value incorrectly truncated during reading due to implementation limitations

But luckily that doesn't seem to influence the result. Still I would like to know what it is trying to tell me and google doesn't know :)

2) when loading the layer it takes at least 20seconds for mapserver to show it. I understand it is because of big amount of data? (50files, all in all 40MB) Is there any way to speed this up?

Thank you very much for your help!

Janosch

You need to create a tileindex using gdaltindex, and then reference that
tileindex in your layer.

See the RASTER HOWTO for details, chapter 4:
