Hi folk,
I need to publish a floating Erdas Image img file. A stretched scale of
red is required.
Starting mapfile could be:
....
LAYER
NAME "test"
TYPE RASTER
DATA "rd_7790432.img"
TEMPLATE "ttt"
TRANSPARENCY 60
METADATA
"force_imagetype" "jpeg"
END
....
I need a CLASSITEM setting, but how can I manage a floating raster? 255
classes or less can be fixed:
Single class example:
CLASSITEM "VALUE"
CLASS
NAME "0 m - 900 m"
EXPRESSION ([pixel] >= 0 AND [pixel] < 900)
STYLE
COLOR 0 20 0
END
END
How can I do automatically for all the pixel value?
Thanks.
Simone
