Ground System Changes since LGSOWG-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 since LGSOWG-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 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.

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.
