Entering a New Landsat Era: Already Operational! Randolph H. Wynne Presented to Pecora 17
Landsat data enable • Operations, not just science • Managing, not just monitoring • Dynamic, not just static, information • Management-scale, not just coarser-scale, analyses
Landsat Importance The Landsat program provides the only inventory of the global land surface over time at a scale where human vs. natural causes of change can be differentiated on a seasonal basis with superb radiometric qualities No other satellite system is capable/committed to even annual global coverage at this scale
Already Operational • While many of us have been working hard to ensure (finally!) operational status of the Landsat program, a large base of users has been relying on the data stream for many years • Examples will be given from the forestry sector

Productivity Assessment– all unthinned stands > age 5 1,009 acres with peak LAI > 3.0 1,130 acres < 1.0 5,420 acres <1.5 We need to look at these and diagnose the problem With LAI values, the Data Warehouse provides ability to query and report

Competition Control - Woody 3 year-old plantations Polygon > 20 acres
LAI (Leaf Area Index): • stand stratification for inventory • identification of poor-performing stands for early harvest • identification of stands with high levels of competition LAI plus GE (Growth Efficiency) Provides ability to estimate stand-level response to silviculture: (fertilization, release, tillage) Growth = 3.9 tons Growth = 7.2 tons Growth = 5.1 tons

Ecosystem Services • Resources and processes supplied by natural ecosystems • Include, but not limited to, water quality, biodiversity, carbon sequestration
Modeling Ecosystem Services at the Tract Level Using Remote Sensing EcoMetrix is a joint project of the Virginia Department of Forestry, USDA Forest Service, Virginia Tech, and other Commonwealth of Virginia and Federal agencies. EcoMetrix will provide spatially-explicit, web-based quantification of ecosystem services using extant best of breed models at the tract level. Two initial foci are carbon and water quality/quantity; short-term plans for biodiversity

Already Operational • While many of us have been working hard to ensure (finally!) operational status of the Landsat program, a large base of users has been relying on the data stream for many years
What Next? • The mandate we have is bigger than we thought, as Landsat, like the weather satellites, is now a key element of the infrastructure on which our economy and environmental monitoring and management increasingly depend
