Hi, I'm exploring the possibility of a GDAL driver for TIDEDA datasets. For a description of TIDEDA, see: http://www.niwa.co.nz/software/tideda-time-dependent-data
Briefly, it is a tool for managing timeseries data from sources like climate & hydrometric stations. NIWA is considering Open Sourcing the tool, and enabling interoperability with other Open Source tools & supporting data delivery via web services (ie: via GDAL & mapserver) seems like a very useful step (whether or not we do open up the codebase - it will be useful to the users). The preferred (& obvious) web services to use are OGC:SOS & OGC:WCS (WCS as a 1D time series). From a client perspective I'd like to use WFS as the site/station discovery service, then drill down to the data from the sites with SOS/WCS. Superficially at least, it seems that a GDAL/mapserver combination is well suited to this task. Can anyone here comment on how realistic this might be? Any developers interested in undertaking the work required - initially a GDAL driver talking to the TIDEDA api? Is the WCS & SOS support in mapserver able to support 1D timeseries data? Does anyone know of a CWS client that supports 1D timeseries content? Thanks, Brent Wood
