.map and .tab files

[Brent Fraser]

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 include 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 it
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 given 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"
(3445375,5560000) (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
NAME praha
STATUS ON
IMAGETYPE PNG
SIZE 800 500
SHAPEPATH
"/opt/SUNappserver/domains/domain1/applications/j2ee-modules/test8"
EXTENT 3445375 5539 250 3474000 5560000
UNITS METERS
PROJECTION "proj=tmerc" "lat_0=0" "lon_0=15" "k=1" 'x_0=0" "y_0=3500000"
END
WEB
IMAGEPATH "/opt/SUNappserver
/domains/domain1/applications/j2ee-modules/test8/"
IMAGEURL "/test8/"
END
LAYER
NAME "Nighttime lights"
TYPE RASTER
STATUS ON
DATA
"/opt/SUNappserver/domains/domain1/applications/j2ee-modules/test8/praha.tif
"
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 missing anything?
Thank you
Jose Luis
