.map and .tab files

[Brent Fraser]

Jose Luis,

  Make sure the .tfw files are in the same directory as the image files and named the same (except for the prefix part).  For example,

        image1.tif
        image1.tfw
        image2.tif
        image2.tfw

The tfw file is associated with the image file automatically based on the file name.

  Hi Brent and all the rest.

  I have resolved the problem just as I told you, thanks to your solution, but I have a problem related to it, and I do not know how to solve it.

  In the begining I only was using one map, so I included the .tfw file manually en th WEB-INF directory and that was all. But now I use many maps, and I have to include the correct .tfw file depending on the map I use.

  So is there any mapserver instruction so I can associate the .tfw to the mapObj I am generating? Or what is the way of doing it?

  Thank you to all

  Jose Luis

  P.D. I am using Linux, and Mapserver 4.4.1

    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
    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 "pro j=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 missin g anything?
    Thank you
    Jose Luis
