[Esip-drone] Follow Up: Drone + SemTech Telecon Presentations

[Lindsay Barbieri]

Hello Drone & SemTech Clusters,


We had a great joint-cluster Telecon last week discussing the OGC/W3C Semantic
Sensor Network Ontology, thank you again to our speakers Krzysztof Janowicz and
Josh Liberman and all in attendance. We're looking forward to continuing
this conversation in future telecons and during the ESIP Summer Meeting and
the Drone Data Management Workshop
<https://mfr.osf.io/render?url=https://osf.io/kshcd/?action=download%26mode=render>
(flyer & link to sign up if you'd like to participate).


Here is a YouTube link
<https://www.youtube.com/watch?v=QAUWrCpIRI0&feature=youtu.be> to the
presentations. There was also a lot of great discussion happening in the
chat, summarized below, and will also be put on the Drone Cluster wiki.

Notes from Lewis: This addresses three primary things: DOMAIN, RANGE and
RANGE METADATA


   1.

   The domain of the coverage is the set of points in space and time for
   which we have data values. For example, in a river gauge measurement, the
   domain is the set of times at which the flow was measured. In a satellite
   image, the domain is the set of pixels. In a weather forecast, the domain
   is a set of grid cells.
   2.

   The range of the coverage is the set of measured, simulated or observed
   data values. A single coverage may record values for lots of different
   quantities; for example, a weather forecast predicts values for many things
   (temperature, humidity etc.) on the same domain. So the range of a coverage
   often consists of several lists of data values, one for each measured
   variable. Each element within each list corresponds with one of the
   elements of the domain (e.g. a pixel or grid cell).
   3.

   The range metadata describes the range of the coverage, to help users to
   understand what the data values mean. This may include links to definitions
   of variables, units of measure and other bits of useful information.
