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

I'm just getting started with Mapserver and have worked my way through the tutorial made by Pericles S. Nacionales. Now I have started to work on my own mapserver application but am experiencing some problems. I have a shapefile of my hometown which I use as the background layer. Now I want to add Raster Data, I have 50 georeferenced tif tiles of the area. I could add them in an own layer each but I would rather like all these tiffs to be in one layer. Is there a way to tell mapserver to use all tiffs in a folder for a layer? If not, what would be the best way to combine these tiffs into one big image? I hope you can help me out :) Best Regards Janosch Diese E-Mail kann vertrauliche und/oder rechtlich geschützte Informationen enthalten.

RE: [mapserver-users] combine many georeferenced tifs in one layer
You can do the following things to speed up performance: * create a spatial index on your tileindex shapefile with shptree (also make sure you reference your TILEINDEX in the MAP file without the .shp suffix) * create overviews in the tiff files using gdaladdo Best regards, Bart -- Bart van den Eijnden OSGIS, Open Source GIS http://www.osgis.nl - Oorspronkelijk bericht Van: [EMAIL PROTECTED] Naar: mapserver-users@lists.osgeo.org mapserver-users@lists.osgeo.org Onderwerp: RE: [mapserver-users] combine many georeferenced tifs in one layer Datum: 10/03/08 10:51 Thanks a lot Bart and you too Till!

Re: [mapserver-users] combine many georeferenced tifs in one layer
not using the suffix causes mapserver to look for .shp and .qix which is the quadtree index file. Using .shp suffix causes mapserver looking for foo.shp.qix and not finding it, and not using your foo.qix Guillaume Mike Meier a écrit : Hi Bart, why without .shp suffix? I don't find this hint at the Mapfile reference or in a Trac Ticket.
