--- Start of Idrisi List message Happy New Millenium to all Idrisians! Here comes all responses (in entirety) to my request on how to import GeoTIFF data into Idrisi. Thanks Tammy, Pedro, Peter and Gary! I have only tried to use the approach/tool offered by Tammy Woodard which "works"; I use BILIDRIS upon the GeoTIFF image, and this works out with the exception that left and right part of the image is switched.... I include the other answers so that others may proceed testing/using them.

I have as yet not found a way to import this format, neither in the nice way (i.e., a correct importing also of the meta-data), nor a method to strip off the header info since BIPIDRIS, BILIDRIS & PARE do not accept headers > 32,6K and the GeoTIFF header is > 68K.

To: Sindre Langaas <[EMAIL PROTECTED]> Sindre, The new impexp.dll will be sent to everyone on the CD that is the first service release. This is planned to be sent out around new years. If anyone specifically needs it sooner than that, we can send it to them.

To do this you can use the listgeo.exe available in at ftp://ftp.remotesensing.org/pub/geotiff/libgeotiff/ ( for WinNT is the geotiff_bin_111_nt.zip, but you have also the IRIX and LINUX versions). I think that this was compiled by Frank Warmerdam ([EMAIL PROTECTED]) and the source code is available. This program (listgeo.exe) will give you all the geographic tags present in the Geotiff file. Then you have to convert the tiff file to some kind of tiff format that IDRISI reads. From my experience with the previous version of IDRISI it worked well in the Tiff format that Adobe Photoshop produces (no Thumbnail, no LZW compression and IBM-PC byte order) I do remember that IDRISI didn't like the tiff from Paint Shop, but I dont know how the new version reacts to them :) After the tiff conversion all you have to do is use tifidris and then add to the doc file the geographic tags that you take from the listgeo.exe Hope this helps, Pedro -- Pedro Pereira Goncalves -------------------------- inovaGIS Project http://www.inovagis.org/ Response 3 ================================================ Date sent: Fri, 17 Dec 1999 13:15:36 -0500 From: Peter Schlesinger <[EMAIL PROTECTED]> Subject: GeoTIFF importing?

Response 4 ================================================ From: Tech Support <[EMAIL PROTECTED]> To: 'Sindre Langaas' <[EMAIL PROTECTED]> Subject: RE: GeoTIFF importing? Date sent: Tue, 14 Dec 1999 12:31:16 -0500 Dear Sindre, >From what I understand about this format, the TIFF is a variant subformat not supported by Idrisi for Windows Version 2. I believe it's a 16 bit compressed TIF. IfWv2 only imports 8-bit uncompressed TIFs. You can convert the TIF to an importable format using a number of graphics packages. In fact, there is a shareware package named THUMBS that is avaialable for a 30 day trial for free from the web... http://www.cerious.com. I've used this myself for this same operation. Let me know whether or not this works... Thanks! -Gary Votour Clark Labs Cuustomer Suupport --- End of Idrisi List message IDRISI-L is an unmoderated list.
