SOS Profiling

Profiling means that you can define the default behaviour of the SOS. For example, the default responseFormat if it is not requested or if the featureOfInterests should be encoded in the observations or only referenced.

Currently, the SOS profiling definition is based on a XML file but in the future the definition and activation should be possible via the admin interface.


The XML schema describes how a profile XML file should be structured and which elements are required or optional.

In the schema you can find the <documentation> elments which describes the meaning of the defined element.

Activating a profile

Up version 4.3.x

Due to the use of XML files to define a profile it is necessary to modify the files and reload the SOS instance to activate another profile.

The profile XML files can be found in [TOMCAT_HOME]\webapps\[SOS_NAME]\WEB-INF\classes\profiles.

To activate another profile do the following steps:
  • Open the profile file you want to activate in an editor
  • Change <profile:activeProfile> to true and save changes.
  • Open the former active profile in an editor
  • Change <profile:activeProfile> to false and save changes.
  • Reload the SOS instance.

From version 4.4.x

From version 4.4.x it is possible to activate the profile via the admin interface and a reload the SOS instance is no longer necessary.
  • Go to Admin -> Settings -> Profiles
  • Select the profile in the drop-down list
  • Presss activate

Available profiles

Currently, the SOS provides two profiles, the default profile and the hydrology profile.

Default profile

With this profile, the SOS behaves as described in the OGC SOS 2.0 specification.

Here is the default-profile.xml file:
    1	<?xml version="1.0" encoding="UTF-8"?>
    2	<profile:SosProfile xmlns:profile="" xmlns="" xmlns:xsi="" xsi:schemaLocation=" sos-profile.xsd">

    5	    <profile:observationResponseFormat></profile:observationResponseFormat>

   19	    <profile:returnLatestValueIfTemporalFilterIsMissingInGetObservation>false</profile:returnLatestValueIfTemporalFilterIsMissingInGetObservation>
   20	</profile:SosProfile>

Hydrology profile

With this profile, the SOS behaves as described in the OGC Sensor Observation Service 2.0 Hydrology Profile.

The main differences to the default profiles are:

Here is the hydrology-profile.xml file:
    1	<profile:SosProfile xmlns:profile="" xmlns="" xmlns:xsi="" xsi:schemaLocation=" sos-profile.xsd">
    2	    <!-- 
    3	        NOTE: If you use this Hydrology-Profile with the old concept (not the series concept) and without the SOS 
    4	        transactional profile the ObservationConstellation and ObservationType tables and mapping files are required to work!
    5	        You can find the ObservationConstellation and ObservationType tables in the 
    6	        [TOMCAT_HOME]\webapps\52n-sos-webapp\WEB-INF\classes\mapping\transactional folder of the deployed SOS.
    7	    -->
