GRASS GIS doesn’t have any module to work with Sensor Observation Service (SOS). SOS is an Open Geospatial Consortium (OGC) standard and it is useful to implement modules to work with this standard into GRASS. Intended modules would enable the user to create a vector with or without the observation values, create a raster for each queried day and create a space time vector or raster dataset. One module would also allow the user to convert a space time vector dataset into a raster dataset. The user should be also allowed to get the capabilities to get info about sensors from these modules and filter the results.
