Jose Luis,
I had a quick look around and could not find a document that listed all
the ellipsoids supported by Proj. As Norman Vine pointed out, the best
place to get that information is the proj executable itself, if you've got
it compiled. Here's the output from proj 4.4.9 (the results are formatted
better by a fixed-pitch font such as courier):

Thank you, very much again, it finally seems to work.
I have a question for you:
Once I know that it is a Krassovsky ellipsoid, how do you know the exact
word to put in the ellps option of the projection.
I mean, how did you know you had to put "ellps=krass" and not
"ellps=krassov" or "ellps=krassovsky" for example?
Where are the possibe values of the parameters of the projection defined?
regards
Jose Luis

For a world file description, have a look at:

Sorry about the ellps info (it's not Clark 1866). Your tab file shows 1001
as the datum code. From the MapInfo doc, this indicates a datum of Pulkovo
1942, which uses the the Krassovsky ellipsoid. Your PROJECTION object
should i nclude the Proj4 keyword of "ellps=krass"

Sorry but I don't undersand what to do in point number 1.
How can I do a .tfw file? How does it look like?
and respect to point 3: how do you know which is the ellps parameter?
Thanks

Jose Luis,
Three possibilities:
1. The tiff might be a plain tiff, not a GeoTiff (with registration info
attached as a TIFF tag). Make a .tfw georeferencing "world" file for i t
using the information in the TAB file
2. You may have your false_easting and false_northing values swapped in the
PROJECTION object of your map file. Double check with the CoordSys
statement in t he TAB file.
3. No ellipse is gi ven in the PROJECTION object. Add "ellps=clrk66"
Since your output projection is the same as your input projection, you could
just remove the two PROJECTION objects in your map file. You would stillneed
to make a world file for the tiff file.

Hi everyone
I can not manage to draw a raster I have.
This raster is a .tiff file that has associated this .tab file:
!table
!version 300
!charset WindowsLatin2
Definition T able
File "praha.tif"
Type "RASTER"
(3445375,5 560000) (0,0) Label "Pt 1",
(3474000,5560000) (4507,0) Label "Pt 2",
(3474000,5539250) (4507,3266) Label "Pt 3"
CoordSys Earth Projection 8, 1001, "m", 15, 0, 1, 3500000, 0
Units "m"
RasterStyle 7 0
When I put this data to the .map file I write it as:
MAP

IMAGETYPE PNG
SIZE 800 500
SHAPEPATH
"/opt/SUNappserver/domains/domain1/applications/j2ee-modules/test8"

PROJECTION "proj=tmerc" "lat_0=0" "lon_0=15" "k=1" 'x_0=0" "y_0=3500000"
END
END
END
Am I doing it correctly?
Am I missin g anything?
Thank you
