HI all,

Can anyone help me insert a WMS layer (it is an image) we are hosting into the API we have operational? Just cannot see to get it to work. I suspect it is a layer name problem or we are not using the correct URL. I can view it in WMS viewing software such as arcgis UDIG so I suspect it is hosted correctly.

We are using the API located at http://www.wm.edu/as/cga/Online%20GI...s/AngevinMaps/

I am hosting my own WMS layers at
http://cga.campus.wm.edu/ArcGIS/serv...ver/WMSServer?

Layer name = Deneze

Full code is below.

Thanks

Stuart

J'ai fait une page d'essai:
http://atlasnw.free.fr/geoportail/exemples/wms_cga.html

mais on ne voit pas beaucoup de données wms

[trukker]

En désactivant toutes les couches sauf la couche wms, et en se positionnant dans le coin supérieur gauche avec les flèches du clavier ou la souris, le message d'erreur suivant s'affiche :

Parameter 'layers' contains unacceptable layer name.
Parameter 'width' contains unacceptable value



I've deactivated all layers except wms layer of the mga_geo exemple and whith the mouse, dragged the wms layer on the left top, then I saw this error message :

Parameter 'layers' contains unacceptable layer name.
Parameter 'width' contains unacceptable value

Thanks this has been a help.

I created a test page at http://www.wm.edu/as/cga/Online%20GI...evinMaps/test/

You can see what we have. But around the town of Deneze you should see the WMS layer. I cannot see the layer I am hosting at var url_wms = "http://cga.campus.wm.edu/ArcGIS/services/Watkinson/MapServer/WMSServer?Deneze

Here is a map of how it should look

http://cga.campus.wm.edu/ArcGIS/rest...Server?f=jsapi

It works in REST the WMS works in Desktop apps such as U Dig but I feel I must have an extent or projection error as it will not display in this API

Je m'intéresse à l'impression sous IE8.
Et sur votre page test, le bouton "Print" qui est OK sous FF3, envoie une erreur bloquante, ici, sous XP/IE8...

Parameter 'width' contains unacceptable value

In Mapserver, default max width is 2048 ...

[dgrichard]

Parameter 'layers' contains unacceptable layer name.

According to the GetCapabilities operation of your ArcGIS, the layer name is '4' and not 'DENEZE' :

http://cga.campus.wm.edu/ArcGIS/serv...071&HEIGHT=726

So, replace :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
layers: 'DENEZE',

with :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
layers: '4',

Nevertheless, it seems removing the error, but the image keeps being blank ... cause (again with the capabilities) the bounding box for the layer and the GetMap bounding box do not overlay (could you resize the bbox on server side ?)

In the new version proposed by stuartehamilton

http://www.wm.edu/as/cga/Online%20GI...evinMaps/test/

there is only this error message

Parameter 'layers' contains unacceptable layer name.

Dans Qgis, la couche s'affiche correctement.

It displays correctly in a few Open Source Apps I have tried including UDIG so I am very reluctant to change the extent.

OKAY Thanks all. The number was the key. I changed it to 0

It now shows on the map!

The last problem is the white border! Big problem? Why does it have a solid white surround? The original layer is a GeoTiff being served as a PNG. You do not see the white surround in Google Earth, QGIS, UDIG etc (well at least not this big).

One of the big reasons for me using the API is to have the imagery and cadastral data integrated with our information but this nuisance surround ruins what we are trying to achieve. Any ideas of how to remove this white surround would be appreciated.

Thanks for everyone's help. I have plenty of these layers, this is just a trial to get everything working before I load everything.

Again the problem is the white surround

on Deneze layer 0

Again the problem is the white surround

Try transparent:'true' in the WMS params (after: layers:'0' for instance).

The example for WMS is over there.

This is resolved!

Great Forum.
