Hi to all,
I've a problem with the loading of a raster image via WMS (1.3.0).
To load the layers of my project I use gvSIG. If I load my digital elevation
model (DEM) directly from filesystem (which is a HFA/Erdas Image file - .img),
x and y pixel dimension are fixed to 2.5 and -2.5 meters respectively, and
fixed are also the width and height attributes.
If I load the layer from
Mapserver's WMS instead, x and y pixel dimension change as I zoom in or out (i.
e. changing the width
and height parameters of the getMap request).
Is there
the possibility to tell the wms client that x and y pixel dimension are
constant and should never be calculated?
Here's my layer definition and the
tiff outputformat definition:
OUTPUTFORMAT
NAME GTiff
DRIVER "GDAL/GTiff"
MIMETYPE "image/tiff"
IMAGEMODE FLOAT32
EXTENSION "tif"
END
LAYER
NAME
"my_dem"

END

TEMPLATE "void" # enable queryable attribute on the layer
END
Any help is
appreciated,
Flavio
