Apart from WMS parameters, the GIServer accepts layer-specific parameters.
These parameters enhance the interactivity of the requests and give a direct linkage to the GIS data.
When requesting these parameters it is necessary to specify to which layer are they refering. For example,
if the request is to drawn a NOAA image with the palette color schema number 3, it is necessary to specify :
<dataset>.<layer>.PAL = 3
Even if the GIServer parameters do NOT respect the WMS specification, all these non-WMS conformant
parameters might be transformed in to style definition
(see Styles and GIServer Parameters)
For raster data the following parameters are defined:
- .pal (also available for vectorial data)
This integer parameter defines the palette to be used. Check out the possible values at the inovaGIS help files.
REQUEST=GETMAP&
LAYERS= PORTUGAL.NOAA, PORTUGAL.NUT2, TERRA.BORDERS&
BBOX=-10,35,0,45&
SRS=EPSG:4326&
WIDTH=250&
HEIGHT=250&
FORMAT=JPEG&
STYLES=,DEFAULT,DEFAULT&
TIME=2000-08-09&
DIM_BAND=3&
PORTUGAL.NOAA.PAL=1
- .maxvalue
This integer parameter defines maximum value to display in the raster data.
The color distribution is made not from the real max and min values but with the maximum value requested.
REQUEST=GETMAP&
LAYERS= PORTUGAL.NOAA, PORTUGAL.NUT2, TERRA.BORDERS&
BBOX=-10,35,0,45&
SRS=EPSG:4326&

HEIGHT=250&
FORMAT=JPEG&
STYLES=,DEFAULT,DEFAULT&
TIME=2000-08-09&
DIM_BAND=3&
PORTUGAL.NOAA.MAXVALUE=
- .minvalue
This integer parameter defines minimum value to display in the raster data.
The color distribution is made not from the real max and min values but with the minimum value requested.
