[esip-semantictech] [EXTERNAL] More information on SELFIE: the Second Environmental Linked Features Interoperability Experiment

[David Blodgett]

I'd be game to work more on the LDaaS concept. Need to find the right niche, but there is certainly a need and ESIP is a good neutral-ground that could help fill a community need.

Long term, HUCs should not change, but our knowledge of how rivers connect at the continental scale is not perfect yet... getting there. I like the idea of a session on the intersection between important features and feature-oriented observations and various remotely-sensed and modeled data products (cell/raster-based or feature-coverage based). I've got a related session I need to submit actually... 

SELFIE use cases are basically wide open. One I would love to pursue would be how to go from an identified feature (maybe a HUC or a county) to a useful collection of remotely sensed information that overlays or is otherwise related to that feature. In our ID -> info -> data resource model, it's clear that "data" need not be limited to representations of the thing that is identified, but could be interesting related data like an elevation surface or observed landcover etc. -- the key is that SELFIE participants bring their own use cases and commit to use interoperable and adoptable approaches as a group.

I did speak to Annie previously about ‘potentially’ getting some funding e.g. Labs project, to advance this concept. IMHO part of this effort is an initial exercise comprising gathering of stakeholder needs and requirements from such a system. We could then justify, to what extent an LDaaS system is needed and what for. I suspect that some aspect of IRI and resource governance will come up as part of this.

I firmly think that we need to lead this from within SemTech @ESIP, OGC ELFIE/SELFIE, etc. to demonstrate some level of community need and concept/technology maturity. I also think that this would make an excellent session for the summer meeting.
