CCRS Satellite Receiving Stations Gatineau Satellite Station Prince Albert Satellite Station
Multi-Mission Activities Presently receiving: • RADARSAT-1 • ERS-2 • ENVISAT ASAR • LANDSAT-5 TM • NOAA-18 AVHRR FUTURE: • LANDSAT Gap-Filler, Follow-on • RADARSAT-2 • ENVISAT MERIS
AGENDA • LANDSAT Archive Statistics • Ground System Changes • LTWG Action Item Responses • Data Distribution Statistics • Summary
CCRS LANDSAT ARCHIVE(As of September 30, 2006) • ETM+ (Landsat 7) • 144,236 scenes • Approximately 59 TB • Archive last entry: 30 Apr 2005 • TM (Landsat 4 & Landsat 5) • 318,830 scenes • Approximately 82 TB • Landsat 5 Archive grows by 22.6 GB daily (summer season) • MSS (Landsat 1 through 5) • 303,718 scenes • Approximately 10 TB
Ground System Changes sinceLGSOWG-34 • Operations • Maintained Over a 99.64% L5 TM Data Capture Success Rate • 100% Successfully Archived • Continue migration of all historical data to new Sony robotic tape archive system (petasite) over the next few years. • System Upgrades • Upgrade Landsat MSS in-house processor to process Landsat ETM+, up to Level-1 (SLC-on). • Landsat TM RCC data validation.
Ground System Changes sinceLGSOWG-34 • Future Plans • Upgrade CCRS catalogue to incorporate OGC-compliant protocols to ensure interoperability with the USGS catalogue. • Transcribe all remaining Landsat 4-5 TM data to robotic system. • System upgrade for Landsat 1-5 MSS data catalogue (metadata and browse) capability.
LGSOGW 34 - Action Item 1 Response • Action: ICs to review the L5 MOC-IGS ICD draft document with the new metadata definitions and return comments to Rynn Lamb. • Due: December 15, 2005 • Response: CCRS provided feedback to USGS.
LGSOGW 34 - Action Item 2 Response • Action: ICs to review the draft L5 TM Data Validation and Exchange Plan and the updated L7 Data Validation and Exchange Plan and return comments to Rynn Lamb. • Due: December 15, 2005 • Response: CCRS interacted with USGS. Landsat 5 TM data was exchanged and validated in April 2006.
LGSOGW 34 - Action Item 6 Response • Action: ICs to send to Laura Rocchio any documents they have of historical importance, such as MOU negotiations, local histories, early LTWG/LGSOWG handouts. • Due: By LTWG #15 • Response: CCRS has not yet identified any significant Landsat legacy documents for this action.
LGSOGW 34 - Action Item 14 Response • Action: All ICs to think about the frequency of meetings. Send to Kristi Kline either an email or a letter (on letterhead is preferred), with a copy to Steve Covington, containing your thoughts on whether we should have two meetings or one meeting each year. • Due: December 31, 2005 • Response: CCRS considers one LGSOWG meeting a year is sufficient.
LTWG-15 – Special Request • CCRS delivered a CD to USGS at LTWG-15 with metadata report for Mid-Decadal Global Land Survey (MDGLS). The metadata report was in USGS specified format for Landsat 5 and 7 data received by CCRS from April 2004 to 31 March 2006.
LTWG 15 - Action Item CAN03 Response • Action: USGS and CCRS to arrange a data exchange of pre-SLC L7 data coverage over Ellesmere from USGS to CCRS. • Response: CCRS successfully ingested some 50 L7 ETM+ scenes in Raw CC format from USGS for Canadian Arctic mapping.
Data Distribution Statistics • LANDSAT 1-5 MSS • LANDSAT 4-5 TM • LANDSAT 7 ETM+
Summary • LANDSAT-5 operations uneventful. • LANDSAT data continues to be utilized. • Significant concern with the increasing probability of a gap in LANDSAT data continuity has resulted in user discussions on possible ways to deal with a Landsat gap.
