This is the project page for the IOOS customized build of the 52°North Sensor Observation Service (SOS).
i52n-SOS extends the stock upstream 52°North (52n) SOS with IOOS specific encoding formats, test data, and more.
The IOOS custom encoding formats include:
- Enhanced GetCapabilitiesResponse (extra metadata)
- Enhanced SensorML (extra metadata and network/station/sensor hierarchies)
- O&M and SWE (IOOS m1.0 SOS format)
- netCDF (CF 1.6/ACDD 1.1/NODC 1.0/IOOS 1.0 conventions)
- application/x-netcdf - single sensor/observed property
- application/zip; subtype=x-netcdf - zipped, supports multiple sensors
NOTE: netCDF encoding formats require the installation of the netCDF4 C library on the server.
For Debian/Ubuntu systems, this is the
The IOOS test data:
- Generates network, station, and sensor procedures
- Uses IOOS SensorML formats and metadata
- Uses CF standard names for observed properties
- Uses udunits
- Generates time series and time series profile data
- Randomly generates global station locations
- Includes test client example requests matching test data values
The project currently aims to conform to the IOOS SOS Milestone 1 Standard.

Testing the i52n-sos implementation
The i52n-sos implementation of the IOOS SOS specification can be tested using an (incomplete) collection of CTL tests. See the ioos-sos-compliance-tests project.
