Greetings,
Having a blast using ka-map and mapserver, but ran into a bit of trouble when
including a layer from a postgis source.
here is the layer defs from my map file, which work fine in a dbox-style
mapserver application:
-----------------
LAYER
NAME "county-boundaries"
TYPE POLYGON
PROJECTION
"+proj=aea +x_0=0.0 +y_0=0 +lon_0=-96 +lat_0=40.0
+lat_1=20 +lat_2=60.0
+datum=NAD83"
END
DATA "gen_2 from poly_county using unique county_id"
CONNECTION "user=xxx password=xxx dbname=tiger2005se host=localhost
port=5432"
CONNECTIONTYPE postgis
STATUS DEFAULT
TRANSPARENCY ALPHA
STATUS DEFAULT
MINSCALE 24000
LABELMAXSCALE 2037392
LABELITEM "county_name"
CLASS
NAME "County Boundaries"
STYLE
ANTIALIAS TRUE
WIDTH 2
OUTLINECOLOR 1 1 1
END
LABEL
TYPE TRUETYPE
FONT sans
SIZE 13
ANTIALIAS TRUE
COLOR 20 20 220
OUTLINECOLOR 255 255 255
POSITION CC
PARTIALS FALSE
BUFFER 2
END
END
END
----------------
I read here
(http://lists.maptools.org/pipermail/ka-map-users/2005-December/000721.html)
that ka-map will only work with postgis data if the projection string in the
layer defs matched the SRID of the geometry itself.
noticing that my geometry columns had an incorrect SRID, i changed this with
the postgis function setsrid() ... however when this layer is enabled, ka-map
will not generate tiles. also, tile.php returns the following error:
Call to a member function on a non-object in /data1/website/kamap/tile.php on
line 225
this appears to be where ka-map is either creating or saving the image:
$szMetaImg = $szMetaDir."/t".$metaTop."l".$metaLeft.$szImageExtension;
$oImg = $oMap->draw();
$oImg->saveImage($szMetaImg);
$oImg->free();
.... i have a fully functional ka-map application using this same set of temp
directories, and config files.
does anyone have any ideas on this?
thanks in advance!
