4. IEEE Patent and Copyright Policy
===================================
1. slides 1-4 were shown and discussed by the chair
2. Chair provided an opportunity for participants to identify patent
claim(s)/patent application claim(s) and/or the holder of patent
claim(s)/patent application claim(s) of which the participant is
personally aware and that may be essential for the use of that
standard.
Wade will try to get this resolved with NGA soon.
===================================
5. Discussion of current draft standard
===================================
We then talked about Chuck’s latest XML version of the discovery
metadata.
control points: has both image-grid and ground coords
valid data: chuck is looking into possible ways to have multiple views
into the raster data, iso 19193
sensor info: sensorML is required, yet not an ISO std.
we need to have an on-line ontology of our terms, so that
this can refer to them using the URL.
grpPosition: being used for sensor posn even though it
refers to “ground reference point”. We need to figure out
a way to fix this.
classification (secret,etc): iso and us-govt don’t agree on how to do
this.
differences: iso country codes: us uses difft codes
classification categories: iso is fairly
brief, us has many more.
we probably want to use the US version of class’n
categories.
the country-codes: we should probably use ISO. could we
use both?
then chuck brought up the idea of combining our metadata with the
actual sar data to make a coverage.
While this is beyond the scope of the std (just metadata), it’s
interesting to look at, and maybe we should consider doing both
instead.
Might be easier to get a coverage into a cataloging system, which is
very important.
=======================
For next time:
Wade said he could come up with a comparison of polynomials vs. grids
in order to try to finish that discussion, as it’s been pending for
over a year.
