1. Call to order
\n(* means voting member):
\n*Leland Pierce
\n*SiriJodha Khalsa
\n*Wade Schwartzkopf
\n*Kevin Romero
\n*Betty Evans
\n*Alexander Awuviri
\n*Craig Stringham
\nDavid Langan
\nEdward Williams
\nGavin Halcrow<\/p>\n
we have a quorum.<\/p>\n
===================================
\n2. Approval of agenda
\n===================================
\n1. Is there a motion for approval of the agenda? SiriJodha
\n2. Is there a second? Craig
\n3. Is there discussion? none
\n4. Is there any opposition? none
\n5. Passes<\/p>\n
===================================
\n3. Approval of minutes of previous meeting
\n===================================
\n1. Is there a motion for approval of the minutes? SiriJodha
\n2. Is there a second? Craig
\n3. Is there discussion? none
\n4. Is there any opposition? none
\n5. Passes<\/p>\n
===================================
\n4. IEEE Patent Policy
\n===================================
\n1. slides 1-4 were shown and discussed by the chair
\n2. Chair provided an opportunity for participants to identify patent
\nclaim(s)\/patent application claim(s) and\/or the holder of patent
\nclaim(s)\/patent application claim(s) of which the participant is
\npersonally aware and that may be essential for the use of that
\nstandard.<\/p>\n
3. responses: None<\/p>\n
===================================
\n5. Overview of SICD std and related SAR stds, contin
\n===================================
\nWade talked about his views of ISO vs. SICD<\/p>\n
1. SICD Collection:
\n ISO AcqInfo: more comprehensive than SICD: consider using
\n ISO MD_Constraints: ditto
\n ISO SensorParams and SARSensor: feels these are not meant for this
\n discovery-type of information. SO don’t use them. Perhaps come up
\n with our own addenda to the existing ISO-discovery metadata related
\n to SAR.<\/p>\n
2. Lineage:
\n likes the ISO stuff, may be useful. Needs more time to better
\n understand it. Not sure that ISO intends it for what we are planning
\n to with it.
\n ISO cv_gridpoint: might make sense to have SICD use this instead of
\n what it currently does.
\n SICD-valid-data: provides a general way to blackout any pixel, more
\n advanced than the ISO-Extent metadata.<\/p>\n
3. SICD Grid:
\n ISO Sensor Model is not really what SICD-grid is doing:
\n SICD is more concerned with the spatial freq domain.
\n maybe iso-19159-sig-processing is more relevant?
\n Need to spend more time to make a better comparison.<\/p>\n
4. Timeline: maybe OK<\/p>\n
5. ISO 19159 has lots of gaps.
\n Just “filling them in” may not be the best approach.
\n Wade likes the lower level structures tht are defined in ISO19159.
\n He plans to work on grid stuff for next time.<\/p>\n
6. Examples of other SAR sensor metadata are perhaps available related
\n to the INSPIRE stds in europe. Still figuring this out….<\/p>\n
7. Wade does not like the ISO cal\/val stds<\/p>\n
8. ISO sensor mode, sorta useful, but assumes rectangular grid, while
\n SAR does not give that.
\n Missing eqns that provide a way to transform from ASR pixel to
\n ground coordinates
\n Unclear how it handles bistatic SAR.
\n Might be worth extending it.<\/p>\n
9. SICD Position description: provides a polynomial.
\n ISO provides state vectors for both Sensor and antenna.
\n Both seem to provide a valid, accurate way to do this.
\n Maybe allow both? Provide way to transform between the 2?<\/p>\n
10. SICD Image formation:
\n completely missing from ISO.<\/p>\n
11. SICD Radiometric:
\n ISO seems to have 1 cal constant for entire image.
\n Really need to have cal that varies across the image.<\/p>\n
12. Issue that because of atmospheric effects the time of each pulse
\n does not really provide an accurate distance estimate.
\n Craig said that this can amount to tens of centimeters, which is
\n significant for some applications.
\n Wade said he would ask Craig for his assistance in dealing with
\n this.<\/p>\n
===================================
\n6. Other business?
\n===================================<\/p>\n
6.1 Radiant Earth and their standardizing efforts
\n what is it: SiriJodha says it’s largely for “discovery”
\n see: github.com\/radiantearth\/stac-spec
\n Since the std we are developing goes far beyond this, not clear
\n what kind of involvement we should have.
\n Especially give the ISO discovery standards that already exist.<\/p>\n
6.2 SiriJodha and Betty are working on a single calendar for all
\n events related to our efforts (SAR, GNSS-R, hyperspectral, etc)<\/p>\n
6.3 IGARSS standards session may need a 40-minute presentation that
\n introduces the area for non-specialists.<\/p>\n
===================================
\n7. Next meeting
\n===================================
\nOur next meeting will be on:
\n Thursday Feb 28, 2019, 10AM US Eastern time<\/p>\n
===================================
\n8. Adjourn
\n===================================
\n1. Is there a motion to Adjourn? Betty
\n2. Is there a second? SiriJodha
\n3. Is there discussion? none
\n4. Is there any opposition? none
