Error determining namespaces from schema component 'null': null

[Zia-]

Hello there,

I'm pretty new to deegree3 after spending years with Geoserver; and pretty much in exploration phase. Below is my coverage xml (name is utah-cov) inside default workspace:

<?xml version="1.0"?>
<Pyramid xmlns="http://www.deegree.org/datasource/coverage/pyramid" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://www.deegree.org/datasource/coverage/pyramid https://schemas.deegree.org/core/3.5/datasource/coverage/raster/pyramid.xsd">
  <PyramidFile>/<path to my geotiff>/Satellite_Provo.tif</PyramidFile>
</Pyramid>

And this one is for layer xml (name is utah-layer):

<?xml version="1.0" encoding="UTF-8"?>
<CoverageLayers xmlns="http://www.deegree.org/layers/coverage" xmlns:l="http://www.deegree.org/layers/base" xmlns:d="http://www.deegree.org/metadata/description" xmlns:s="http://www.deegree.org/metadata/spatial" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

following deegree's docs https://download.deegree.org/documentation/3.5.8/html/#_raster

When I try to hit the following url:

http://localhost:8080/default/services?LAYERS=utah-layer&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fpng&SRS=EPSG%3A26912&BBOX=441174.0000000000000000,4448455.0000000000000000,447810.0000000000000000,4456039.0000000000000000&WIDTH=999&HEIGHT=831

I get:

Above url is an inspiration from

https://demo.deegree.org/utah-workspace/services?LAYERS=orthophoto&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fpng&SRS=EPSG%3A900913&BBOX=-12960414.152967,3755900.069157,-11874396.855243,5788513.5250335&WIDTH=444&HEIGHT=831

Not sure what I'm missing here.

Hi @Zia-,
I was able to replicate the described behavior using your configuration. However, it is expected to not work due to missing configurations files as well as a wrong request URL.

Missing configuration files:

• WMS
  • In the GUI under web services > services > WMS, to match your naming pattern called utah-wms.xml:

<wms:deegreeWMS xmlns:wms="http://www.deegree.org/services/wms" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:dgws="http://www.deegree.org/webservices" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.deegree.org/services/wms https://schemas.deegree.org/core/3.5/services/wms/wms_configuration.xsd">
  
  <wms:SupportedVersions>
    <wms:Version>1.1.1</wms:Version>
    <wms:Version>1.3.0</wms:Version>
  </wms:SupportedVersions>
 
  <wms:ServiceConfiguration>
    <wms:ThemeId>utah-theme</wms:ThemeId>
  </wms:ServiceConfiguration>

</wms:deegreeWMS>

• Theme
  • In the GUI under map layers > themes > standard, to match your naming pattern called utah-theme.xml:

<?xml version="1.0"?>
<Themes xmlns="http://www.deegree.org/themes/standard" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:d="http://www.deegree.org/metadata/description"
  xmlns:s="http://www.deegree.org/metadata/spatial" xsi:schemaLocation="http://www.deegree.org/themes/standard https://schemas.deegree.org/core/3.5/themes/themes.xsd">

  <LayerStoreId>utah-layer</LayerStoreId>


 <Theme>
   <d:Title>utah ortho</d:Title>
   <s:CRS>EPSG:26912 EPSG:4326 EPSG:4258 CRS:84</s:CRS>
   <Theme>
     <Identifier>orthophoto</Identifier>
     <d:Title>Orthophoto of Saltlake City</d:Title>
     <Layer>orthophoto</Layer>
   </Theme>
 </Theme>

</Themes>

Adding these configuration files to your workspace default will make the layer available, here shown in QGIS:

The configuration I created is pretty minimal, so feel free to enhance it!

Lastly, the request generated based on our demo environment results in a HTTP 404 error due to the use of a reverse proxy. Here is your request with the needed changes to work based on your configuration files:

• http://localhost:8080/deegree-webservices/services/utah-wms?LAYERS=orthophoto&TRANSPARENT=TRUE&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&FORMAT=image%2Fpng&SRS=EPSG%3A26912&BBOX=441174.0000000000000000,4448455.0000000000000000,447810.0000000000000000,4456039.0000000000000000&WIDTH=999&HEIGHT=831

or with WMS 1.3.0:

• http://localhost:8080/deegree-webservices/services/utah-wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=40.18441766000000115%2C-111.6917084100000039%2C40.25318049999999914%2C-111.6187039132852163&CRS=EPSG%3A4326&WIDTH=801&HEIGHT=754&LAYERS=orthophoto&STYLES=&FORMAT=image%2Fpng&DPI=96&MAP_RESOLUTION=96&FORMAT_OPTIONS=dpi%3A96&TRANSPARENT=TRUE

I hope the information provided helps you get your deegree service up and running! For a deeper understanding, I recommend reviewing the documentation at https://download.deegree.org/documentation/3.5.8/html/#anchor-configuration-wms.

@Zia- do you have any further remarks/questions?
