[mapserver-users] Mapserver tile generation - google maps

[Wim Vanbelle]

Hi,

Thank you for your time both.

Wouldn't using tilecache imply that I can no longer use dynamic data? My
tiles have to update every minute. Perhaps this is possible with tilecache?
Basically it's only the color value that changes for each object.

An example request that is sent to mapserver:

http://
...maps?map=/.../white.map&layers=%20&mode=tile&tilemode=gmap&tile=264+172+9

MapServer version 5.6.5 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
OUTPUT=SWF OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE
SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT
SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT SUPPORTS=WCS_SERVER
SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI SUPPORTS=THREADS SUPPORTS=GEOS
SUPPORTS=RGBA_PNG INPUT=EPPL7 INPUT=POSTGIS INPUT=OGR INPUT=GDAL
INPUT=SHAPEFILE

My mapfile is configured like this:

        OUTPUTFORMAT
                NAME "AGGPNG"
                DRIVER "AGG/PNG"
                EXTENSION "png"
                MIMETYPE "image/png;mode=24bit;"
                IMAGEMODE RGBA
                FORMATOPTION "INTERLACE=false"
                FORMATOPTION "QUANTIZE_NEW=ON"
                FORMATOPTION "QUANTIZE_FORCE=ON"
                FORMATOPTION "QUANTIZE_DITHER=ON"
                FORMATOPTION "QUANTIZE_COLORS=256"
        END

Although I've used GD as well.  Not sure how I can check the GD & AGG
versions.

I was in the process of making a new build for mapserver with the lastest
versions of everything though. I'll let you know if that would somehow fix
the problem.
