Multi-sensor Remote Sensing for Large-area Forest Inventory in the Northwest Territories

Guillermo Castilla, Canadian Forest Service, guillermo.castilla@canada.ca (Presenter)

The Canadian Forest Service (CFS) and the Government of Northwest Territories (GNWT) are creating a broad forest inventory across 44 million hectares encompassing 80% of NWT forests. Specifically, this collaborative project is creating full coverage estimates (in the form of 30 m rasters) of stand height, crown closure, stand and total volume, aboveground biomass, and stand age derived from a multi-scale sampling design that includes field data, limited airborne and satellite LiDAR, Landsat and RADAR imagery, and other ancillary data. Some of these raster maps will serve as input to CFS spatially explicit Carbon Budget Model (gCBM) that will estimate C pools and fluxes in each forest pixel by combining information on biomass, growth and fire disturbance. In addition, the project will also deliver an integrated polygon map that resembles a traditional forest inventory map and that seamlessly integrates the existing GNWT forest vegetation inventory (FVI, covering < 10% of NWT forests) to obtain a wall to wall product (the Multisource Vegetation Inventory, or MVI) that retains the higher quality information where available. Phase 1 of the project (southern half) was completed last year, and Phase 2 will be delivered in 2018.
