thanks again for your support.
here some answers...
Point 1: I make tests on MGOS on a remote server and on a local AIMS. On
Qgis I use localhost for local AIMS (configured himsel as localhost) and I
use IP for remote server (configured himself with his IP)
Point 2: yes, I already know and I've already played with it with no
success. I don't think the problem is here.
Point 3: I can't clear EPSG:4326. If I do, then QGis give me an error on
BBOX=0,0,0,0. This happens because without EPSG:4326 in row header,
AIMS/MGOS returns capabilities without tag "EX_GeographicBoundingBox". I
think that this is a very important xml tag for QGis, I will explain you
I discovered the following interesting thing by use of fiddler on QGis and
Here capabilities for the layer:
<Title>Infrastructure Map Server - Web Map Service</Title>
- <Layer queryable="0" cascaded="0" noSubsets="0" opaque="0">
<BoundingBox CRS="EPSG:4326" minx="8.371" miny="45.825" maxx="9.174"
<BoundingBox CRS="EPSG:21781" minx="672480" miny="75270" maxx="732911"
Map3D build BBOX values getting them from BoundingBox CRS="EPSG:21781" and
QGis assign BBOX values with an extention a bit wider, getting values from
EX_GeographicBoundingBox (from capabilities) and transforming in something
very closed to this but a bit wider, only a bit: in that case AIMS/MGOS
returns an error without message. If I get QGis request (got from fiddler)
and replace BBOX with values from BoundingBox CRS="EPSG:21781" (from
capabilities), then it works fine.
Conclusion: AIMS/MGOS works with BBOX equal or shorter than what expressed
in GetCapabilities values. BBOX with values outside generate an error.
I think that this is a bug. With this limitation a wide range of WMS client
will not work.
