[mapguide-users] WMS Error

Fri Jun 2 02:06:12 EDT 2006

Hello Thomas,

i can set the bounds in Studio in the Layer Porperties:Service 
Properties:Bounds but it has no effect
for the capabilities doc. I get allways the default capabilties 
(-180,-90;180,90) back.

The EPSG-Code 217810 is defined under ....\Server\nad\epsg or 
....\WebServerExtension\www\nad\epsg Line 3113

I can also set any EPSG:4326 entries: There is also no effect in the 
capabilities doc.....

The Error 599 cames only if try to change these files to my needs:

.../Server/Wms/1.1.1.xml.awd and OgcWmsService.config.awd

I tried this also with the Demodata from Sheboygan, you can also
delete the values for the Bounds in Studio, it has also no effect
for the capabilities doc.

Is there any place where i can set these values instead of studio?

Do i have to set anything in these two files in the wms directory?

Thank you!

Sacha

Since the layer seems to be "published" (shows up in the Capy Doc) I'm assuming that you're already familiar with the properties dialog in MapGuide Studio.  On that dialog, there is an edit control where you specify the bounds for the layer in question.  The syntax is a bit arcane (that's scheduled to change, though... ;-) and for now, you have to be very careful about typing things exactly correct (case matters, and don't forget the ending slash before the close bracket,) but it goes like this:
>
>  <Bounds SRS="EPSG:21781" north="..." east="..." south="..." west="..." />

When you omit bounds information, WMS falls back to some defaults in EPSG:4326, and that's probably what you're experiencing as far as distortion goes.  The fact that 21781 isn't listed in the bounds explains the 559; I'm assuming that the GetMap request is asking for SRS=EPSG:21781.

Because of this, you'll find a numerous instances of "Tolerance and Forgiveness" in our server code, to account for sloppiness in client implementations... in short, not all clients are created equal.

We also played with a version of GAIA a while back, which seemed to be not as reliable as one sample app in their toolkit download, though that may not be the case anymore (I notice there's a GAIA 2 posted on their site.)
