  1. RADARSAT-1 Foreign Data Repatriation September 2015 CEOS WGISS Gary Crocker, Brian McLeod Canada Centre for Mapping and Earth Observation Brian.McLeod@Canada.ca

  2. Road To Now • RADARSAT 1 (R1) Data is Archived where Received; • 51 Ground Stations received R1 Data; • Some Ground Stations combined into one Archive for example: GSS, PASS and ISSF (DLR) in CARCH as FRED; • ASF and McMurdo - one Archive at ASF as Level 0 (swath); • 13 Ground Stations are confidential for all but 4 stations (EV6, Hyades, TAU & NURC), the R1 data is stored at CCMEO and CSA; • 33 Ground Stations except for 2 stations (VIG and DRA), the R1 data is stored at Foreign stations.

  3. Road to Now (continued) • September 2010, CSA released the R1 Foreign Data Consolidation Plan(needs updates) • January 5, 2015, CCMEO and CSA met and agreed on some principles regarding R1 Foreign Data Repatriation. • To apply CEOS recommendations for the preservation of Earth Observation data to the following objectives; • Short-Term objective to archive “transportable data” in FRED format and “Jaxadata” into Canadian archive; • Mid-Term objective to appraise West Freugh (DRA) data and to start on a prioritized basis to archive into CARCH; • Long- Term objective apply the experience gained from meeting the short term and mid term objectives to other R1 foreign data archives.

  4. Repatriation Plan - Structure The overall plan is broken up into four sub-plans: Preservation Plan Short Term Plan Mid Term Plan Long Term Plan Initialization phase activities found in the Preservation Plan (objectives and high level requirements) and Short Term, Mid Term and Long Term Plans (detailed requirements and development); Each sub-plan contains three subsections; Each subsection contains one or more action items; Each action item is assigned a cost in the Cost Model. \

  5. Preservation Plan – Designated Community (DC) • Key challenge lies in foreseeing a future user community and future uses of R1 foreign data archives; • GoCSAR Application Working Group will define the DC; • Consultation with DC (CDC) by CCRS: • CDC AI-1 – identify GoC users of R1 foreign data (complete); • CDC AI-2 – DC specification of preservation requirements; • CDC AI-3 – Cost Model update by CCMEO; • CDC AI-4 – Inform/Confirm with DC.

  6. Preservation Plan - Appraisal • Appraisal based on merit criteria advised by science, risk and cost trade-offs; • Which R1 data sets should be preserved; • Data Set Appraisal: • DSA AI-1 – stewardship, access and distribution; • DSA AI-2 – update to AD B (a CSA document); • DSA AI-3 – visualization tool implementation plan (complete).

  9. Access to R1 data Users discover R1 data using CCMEO Access portal (NEODF/EODMS); GoC users place order with Canadian Government Order Desk (CGOD) at CSA; CGOD submits R1 Production Order to Canadian Data Processing Facility (CDPF); CDPF submits R1 Archive Retrieval Request to Canadian Archive (CARCH/AMS); CDPF processes R1 FRED into Level 1 product; CDPF sends R1 Level 1 product to NEODF/EODMS; GoC users retrieve R1 Level 1 product from NEODF/EODMS.
