## Architecture Integration Supportand the Infrastructure Element Summary

- Aerospace FFRDC Contract
- Independent architecture and integration support to USGS
- EROS TSSC Contract
- Infrastructure Element development
- Ground system integration support to USGS

## USGS LDCM Procurement Status

- Ground Network Element: Trades in process, RFPs expected late 2008
- Flight Ops Team: RFI done; RFP summer 2007; Award early 2008
- MOC Facility (EROS): Location chosen and mods expected in 2008
- Archive and User Portal Elements: RFIs in 2007, RFPs in 2008
- Collection Planning (i.e. LTAP-8), Image Processing, and Infrastructure Elements developed through the EROS TSSC contract
- Updates posted at: _[http://ldcm.usgs.gov/acquisitionStrategy.php](http://ldcm.usgs.gov/acquisitionStrategy.php)_

## System Concept Review (SCR)

- Held February 21-22 at EROS (and the weather was great!)
- Reviewed ground system ops concepts
- Designed to gauge progress towards the Ground System (GS) System Requirements Review (SRR) in August 2007
- Captured 77 RIDs (i.e. action items) in two major groups:
- Policy and L1 requirements issues needing USGS HQ clarification
- Technical issues requiring engineering / science definition or clarification in the operations concept and segment requirements
- Next four slides outline major issues of interest

## Updates to Product Requirements

- LDCM will generate one standard data product
- Precision and terrain corrected (L1T)
- Pixel values will be at-sensor radiance or at-sensor reflectance
- 4000 L1T products per day; 16-bit data in GIS-ready format
- LDCM will focus on electronic delivery of L1T products
- Web-enabled access with no hard media
- L0 “standard” and user specified products not currently planned
- User feedback will determine what others may be considered
- LDCM will support “bulk” data delivery
- Bulk requirements not well understood; User feedback needed
- Initially, bulk delivery on media is planned for “Archive” and L1T data
- Will address requirements through a RFI / questionnaire

## LDCM Standard L1T Parameters

- Parameters based on:
- Feedback from Landsat L1T Pilot
- Current understanding of user community requirements
- Need for consistency with heritage Landsat products
- Pixel size:		14.25m pan / 28.5m multispectral
- Media type:		Download (no cost) – no hard media planned
- Product type:	L1T
- Output format:	GeoTIFF
- Map projection:	UTM
- Datum:		WGS84
- Orientation:		North up
- Resampling:	Cubic convolution
- Accuracy		~12m 90% (CE) global

## Additional Product Related Issues

- LDCM will require user registration for L1T data download
- Will strive to reduce impacts on users
- LDCM will follow COFUR guidelines
- USGS HQ determined COFUR permits web-enabled L1T products
- COFUR allows for applicable charges for user specified & bulk data
- USGS HQ updating Landsat data policy for L1-7 and LDCM

## Other Requirements Issues

- LDCM will support priority acquisition and off-nadir requests
- Will coordinate draft tasking criteria with LST Mission Ops Group
- Criteria will preserve LTAP and be consistent with current missions
- USGS HQ planning a policy statement based LST input
- LDCM will support International Cooperator (IC) community
- At recent LTWG, ICs expressed strong interest in LDCM
- Bulk delivery mechanism will also support data exchange with ICs
- LDCM will support a backup data archive
- Off-site archive planned but with low cost approach
- User feedback indicated costly “hot” backup was not necessary
- Thanks to LST for your quick response to our questions!!

## Ground System SRR Plans

- System Requirements Review planned for Aug 28-29 at EROS
- SRR will assess readiness to begin Ground System (GS) design
- Maturity of the FOS and DPAS segment level requirements
- Allocation of segment requirements to the GS elements
- Ability of the envisioned GS design to satisfy the requirements
- Detailed SRR overview planned on LST agenda this week
- Will outline the SRR, the LST’s role, and review requirements
- LST feedback critical to helping us resolve requirements questions
