In March a Space-and-Time Workshop will take place at the EDC Institute for Geoinformatics (ifgi). Sensor observation data is heavily space and time-related, and the integration of such data in existing tools will cover one part of the discussions for sure.
However, as the IfGI already updated ArcGIS, it was the perfect opportunity to update the adapter to support ArcGIS 10. This also included some (minor) bugfixes, but also to use the current /ArcHydro/Setup10/">ArcHydro tools (v188.8.131.52) as well. Please use and test the new version of the SOS Adapter, so that I can fix bugs as early as possible.
UPDATE: During the tests with the 52°North demo SOS which has several procedures covered in one offering, it became apparant that only one procedure was listed within the timeseries info table. I fixed this bug but did not want to make another version, so be sure have downloaded the latest version by comparing the creation date of the zip.
