[Geomoose-users] Mr Sids Images

[Jim Klassen]

Yeah, that's GIF which is only 256 colors.  If it's an air photo you'll probably be happiest with JPEG output.

The most common output formats should already be defined in MapServer (see http://mapserver.org/mapfile/outputformat.html) so you probably don't need to include that block.

Set 'IMAGETYPE jpeg' in the mapfile should help (http://mapserver.org/mapfile/map.html).

You will find more answers to these sort of questions over on mapserver-users.

Jim:

The map file as this as the output format...is that the same thing??

OUTPUTFORMAT

    DRIVER 'GD/GIF'
    MIMETYPE 'image/gif'

    EXTENSION 'gif'
  END

Thanks!!

I would guess that it is a MapServer issue.  Did you setup MapServer to return JPEG or PNG24 images?  If it is returning PNG they (or any air photo) will look exactly as you describe.

I would recommend you take a look at what MapServer is sending to GeoMOOSE (the FireBug extension to Firefox can be a great help here) and see what they look like and how long they take to render.

I've added our Mr Sids aerials into my Geomoose app, but have a few issues.  First is the reduced number of colors...i.e. they seem to look like the old VGA graphics.  Second is a slow draw speed.

Is the reduced number of colors something I can tweak in Geomoose, or is it a Mapserver issue, or am I stuck because the images are Mr Sids?

Thanks and hope everyone has a great weekend.
