[MapProxy] “could not get any sources: no image returned from source WMS” error in mapproxy demo

[Rahkonen Jukka]

Hi,

You can test WMS services by installing a program like QGis, Kosmo GIS, uDig or OpenJUMP, connecting with you server and reading the WMS layers.  The server URL to use in your case is
http://localhost/cgi-bin/mapserv?map=/home/mwh/osm-demo/basemaps/osm-google.map

You can test WMS also with browser, this should show Finland for you from your service
http://localhost/cgi-bin/ms_ows?map=/home/mwh/osm-demo/basemaps/osm-google.map&
REQUEST=GetMap&
SERVICE=WMS&
VERSION=1.1.1&
WIDTH=903&
HEIGHT=636&
LAYERS=default&
TRANSPARENT=TRUE&
FORMAT=image%2Fpng&
BBOX=683222,8243620,4739737,11100000&
SRS=EPSG:900913&
STYLES=

However, it may be that your test URL is doing the same by reading source data in EPSG:4326 and sending it out re-projected into EPSG:3857 and thus the location of PROJ_LIB is not the reason for your trouble.   Continue with DEBUG 5 and by looking at the log files.

No I did not test whether my WMS service is working and I do not know how to do it. I've just imported OSM data into postgres database, checked whether it shows the map correctly using

http://localhost/cgi-bin/mapserv?map=/home/mwh/osm-demo/basemaps/osm-google.map&mode=browse&template=openlayers&layers=all
Please give me some advice to figure it out.

First of all I've missed an important information to include in my first question post. I am using osgeo-6.05 where MapProxy comes prebuild.
When I execute the command

mapproxy-util serve-develop mapproxy.yaml

It gave me an error as the following




[2013-05-23 16:57:33,558] mapproxy.config - INFO - reading: /usr/local/share/mapproxy/mapproxy.yaml

Since it tells the default port 8080 is used. I thought of a different method. In osgeo-6.05 there is a separate menu








menu called "Start MapProxy". When I hit that option my proxy got started without giving the above error. It produces the following lines when it starts.

After that I used the link

http://localhost:8011/demo/

and viewed the demo site.
