## Global Land Survey 2010 Status Report

- January 6, 2009John Dwyer / Jeff MasekUSGS EROS Center / NASA GSFC

## Background

- Global Land Survey (GLS) data for 1975, 1990, 2000, and 2005 have proven valuable to the research and applications community
- Planning for GLS 2010 is underway
- GSL 2010 MOU has been signed by NASA and USGS
- Landsat TM and ETM+ (no gap-filling) to provide global coverage to the extent possible, using standard L1T processing recipe
- NASA will perform gap-filling of USGS ETM+ products
- Leverage current Landsat routine collections
- Augment routine Landsat collections via campaign stations
- Participation by international data providers has been solicited through the CEOS Land Surface Imaging (LSI) Constellation Working Group on Regional Data Set Compilation (WGRDSC)

## Status

- Telecon with WGRDSC was held Sept 9, 2008
- Terms of Reference were reviewed and agreed upon
- Consensus that regional datasets compiled from international assets should be made freely available
- Defined candidate regions for which agencies should be asked to collect and contribute data
- Brazilian Rain Forest south to Bolivia and Argentina, including parts of the Andes
- Southeast Asia to include China, Vietnam, Laos, and Thailand
- Africa (CBERS-2B)
- Formal solicitation for participation extended to CEOS LSI Constellation Study Team
- Response received from Argentina (CONAE), Brazil (INPE), and JAXA
- NASA LULCC GLS Investigators meeting held Oct 28-29, 2008

## Status of Data Collection Planning

- Campaign Stations
- Russia (Moscow, Irkursk, Magadan)
- Letter of Agreement between USGS and Russia Forest Ministry/ScanEx has been sent to Russians for review
- Collection windows are May 15 – Sept 30, depending upon solar elevation constraints on Landsat 5 solar panels and battery charging
- South Africa
- No longer a formal Landsat International Cooperator
- Will collect during Feb 1 – June 1
- Malindi (ESA)
- Have agreed to collect May 1 – Aug 15 and Oct 15 – Feb 15
- Chetumal
- Formerly operated by DLR but now they only provide technical support
- Need to identify and work with a Mexican government sponsor agency
- Need to estimate level of effort and funding needed for USGS to receive and archive campaign station data for later processing
