[mapserver-users] mapserver 5 TIFF displaying problem

Wed Sep 17 08:22:07 EDT 2008

I'm sorry, I fear I can't help you further.  I'm sure that somebody else will go on with your problem soon.  There must be something odd in the image or in your Mapserver.  You could still try two things and try to find exact reason for the failure:
- use ready compiled Mapserver if you find such for your operating system
- test with another image from different source

	Hi,
	
	thank you but sadly it did'nt help. 
	Changed the DRIVER and translated to GeoTiff, but the problem remained. 
	Even after I changed my .map file projection to EPSG:3301 (same like that .tif file has) was the same picture there.
	If I zoom in/out, then the picture changes a bit ->

	Strange:)

		Hi,
		 
		If all the clients show the same artifacts we can trust they come from the server.  For some reason it does not like your original image.  Try converting it to uncompressed geotiff image with gdal_translate
		 
		gdal_translate -of GTiff 54653.tif 54653_basic.tif
		 
		Make another layer from this new image, or edit your mapfile to use that instead of the original 54653.tif.  What happens? By the way, I believe it should read
		DRIVER "GD/PNG24"

			Hei,
			
			thank you for advice!
			I changed .map a bit:  
			
			IMAGETYPE png24
			OUTPUTFORMAT
			  NAME png24
			  DRIVER "GD/PNG"
			  MIMETYPE "image/png"
			  IMAGEMODE RGBA
			  EXTENSION "png"
			END
			
			output quality looks better, but that black-lined crap is still there:(
			I tried the same with uDig and Gaia WMS-clients, but it's the same.

				Hi,
				 
				It's getting closer.  Image is now at least in a correct place?  Distortion can be due to ArcMAP, perhaps it does not like the outputformat you are using.  Next trials:
				- Have a try with another client software. like Quantum GIS, OpenJUMP, Cadcorp SIS map browser, or just your web browser.
				- Try changing outputformat.  I believe you will need to change it anyway, png is not good for aerial images.  Try png24 or jpeg instead.

					Thank you,
					
					I added PROJECTION block to the layer, but unfortunately the same dance: output is corrupted as it could be seen here: 
					http://picasaweb.google.com/snaperski/Ort#5246933992333025954
					
					Maybe I should compile mapserver without -with-tiff key?

					Tere.
					 
					You have defined the output projection as epsg:4326 and by quick look it is OK in both map projection and WMS metadata.  However, your original image is in Estonian projection, but Mapserver does not know it automatically.  You need to add PROJECTION block to layer definitions as well.  Try editin your mapfile as follows: 
					 
					LAYER
					  TYPE RASTER
					  NAME "raster"
					  STATUS ON
					  DATA "54653.tif"
					PROJECTION
					   "init=epsg:3301"
					END  #end projection
					END #end layer
					
					I hope I guessed the epsg code right.

					Thank you for answering!
					
					There's some additional information. Gdalinfo output:

					And from .map file:
					IMAGETYPE PNG
					 OUTPUTFORMAT

					PROJECTION

					Could it be problem that coordinate systems does not match?
					However, I remember it's written that Mapserver could do SRS transforming on-the-fly.

					Hi,
					 
					Impossible to say with this information.  Much better possibilities to help you if you could send also the main MAP part of your mapfile including at lesast outputformat and projection, and the metadata sections.  Gdalinfo report about the image might be helpful as well.

					Hello,
					
					I'm quite new using Mapserver and found myself struggling with this simple-looking problem:
					
					In my map file, there is layer defined as follows:
					LAYER
					 TYPE RASTER
					 NAME "raster"
					 STATUS ON
					 DATA "54653.tif"
					END
					
					The problem is, that this image is corrupted when I look at it in ArcMap - it contains strange black boxes and stripes. Original image is OK, so
					I guess the problem is somewhere in map file. 
					.tfw file should be ok:
					1.000000000000000
					0.000000000000000
					0.000000000000000
					-1.000000000000000
					650000.500000000000000
					6469999.500000000000000
					
					What could be the problem?
					
					
					Raivo Alla
