Titre : MONITORING ARID LAND COVER CHANGE WITH SIMULATED HYSPIRI DATA

Identification : 5347-13660-007-01R

Pays : Etats Unis

Durée : Oct 1, 2010 à Dec 31, 2012

Domaine : Watershed Protection and Management ; Soil, Plant, Water, Nutrient Relationships ; Conservation and Efficient Use of Water ; Water resources ; Remote sensing equipment and technology

Partenaire : AGRICULTURAL RESEARCH SERVICE - US ARID-LAND RESEARCH CENTER 21881 NORTH CARDON LANE MARICOPA,AZ 85238

Objectifs
This project evaluates the potential value of the proposed hyperspectral/multispectral remote sensing platform known as HyspIRI for assessment of vegetation cover in arid lands ; cover assessment is critical for understanding the surface water budget. Existing airborne remote sensing data will be used to simulate HypsIRI data and to assess how much better land cover monitoring could be with the newer remote sensing technology.

Descriptif
Methods will use existing MASTER and AVIRIS data collected over New Mexico and Oklahoma. Land surface temperatures, emissivities, and reflectances will be estimated. Cover change analysis using emissivity and narrowband visible-near infrared data will be performed using airborne and ancillary ASTER/MODIS data in conjunction with classification techniques. Spatial statistics will help assess resolution and scale effects. MASTER and ancillary data will be used for time scale analyses. Regression analyses will evaluate the significance of different thermal infrared bands
