[OpenLayers-Users] Mapserver and Openlayers - Pink Tiles

Thu Apr 16 07:33:55 EDT 2009

Hi,

You have to tell OpenLayers, which layer(s) to request. Set the parameter
'layers' and you should also with OpenLayers get an image.

layer = new OpenLayers.Layer.MapServer( "Spoortunnel Delft",
                  "/geoviewerbin/mapserv.exe", {map:
"c:/osgeo4w/apps/geoviewer/maps/spoortunnel.map", layers:"Topografie"} );

Hi All,

Thanks again for all your replies.

I got some private replies to my questions here and even though I added
users at openlayers.org to the replies I sent to the repliers to my initial
question here, my e-mail didn't arrive at the mailinglist or on this forum.
Is it possible to send e-mails in a way that they get added to the original
thread?

On-topic again. I've changed quite some things and now the pink tiles are
gone. Instead I have white tiles. :-)

This means that mapserver is generating images, but there was nothing to
draw. Maybe the extent is wrong, but I don't know why. When I use shp2img
with the extent, the image comes out fine. This is the command I used:
shp2img -m spoortunnel.map -e 83600 446000 84600 448200 -o spoortunnel.png

The current code of the html-file, the map-file and the url of one of the
white-tile-images are given below.

Any suggestions?

Best regards, Martijn.
