Greetings list,

I've encountered a problem while trying to publish a sid file. The sid file
does not show in the extent I'm trying to show instead it has a fixed extent
and shows there. 

I got 3 files with the same prefix

kayseri_lokal.sid

kayseri_lokal.sdw

kayseri_lokal.aux

 

I've added this to my mapfile

 

 

LAYER

    NAME "kay_uydu7"

    STATUS ON

    TYPE RASTER

    MAXSCALE 24999

    DATA "uydu/kayseri_lokal.sid"

    GROUP "kay_uydu7"

   METADATA

     "queryable" "true"

    "imageformat" "alpha"

   END

    TRANSPARENCY alpha

    CLASS

    END

END

 

The extent of my mapfile is:

EXTENT 440773 4282202 467369 4295904

 

 

This is the contents of my sdw file which should put the raster on the right
extent:

 

             1.000000000000000

             0.000000000000000

             0.000000000000000

            -1.000000000000000

        440773.000000000000000

        467369.000000000000000

 

 

I've also tried making this a wld file in case gdal does not recognize sdw
file. 

When I type gdalinfo on sid file I get:

When I change the mapfile extent to:

EXTENT 75393 71377 137653 130957

I can see the raster layer normally.But I need to move it to my initial
mapfile extent (since all the other data is there)

Thanks in advance
