Free and open access to the more than 40 years of data captured in Landsat archive, combined with improvements standardized image products increasing computer processing storage capabilities, have enabled production large-area, cloud-free, surface reflectance pixel-based composites. Best-available-pixel (BAP) composites represent a new paradigm remote sensing that is no longer reliant on scene-based analysis. A time series these BAP affords novel opportunities generate information...
Important and complex spatial decisions, such as allocating land to development or conservation-oriented goals, require information tools aid in understanding the inherent tradeoffs. They also mechanisms for incorporating documenting value judgements of interest groups decision makers. Multiple-criteria analysis (MCDA) is a family techniques that makers formally structuring multi-faceted decisions evaluating alternatives. It has been used about two decades with geographic systems (GIS)...
Capture of land cover information is a key requirement for supporting forest monitoring and management. In Canada, provincial territorial stewards use to aid in management planning activities. At the federal level, required meeting national international reporting obligations. To support Canada’s forests, Earth Observation Sustainable Developments Forests (EOSD) project was initiated as partnership between Canadian Forest Service (CFS) Space Agency (CSA), with participation support. The EOSD...
A priority of the Canadian Forest Service and Space Agency joint project, Earth Observation for Sustainable Development Forests (EOSD), is production a land cover map forested area Canada based upon Landsat data. The will be produced through partnership federal, provincial territorial governments, universities, industry. short-term goal EOSD to complete representing year 2000 conditions by early 2006. Over longer term, aim produce products capture changes in forest over time support national...
Abstract The spectrally selective optical properties of wavelength radiation emitters and filters based on periodically microstructured metal surfaces were investigated. Metal structured by the use a holographic mask subsequent etching processes. Due to microstructure, thermally excited surface plasmons couple electromagnetic radiation. Therefore tungsten can act as emitter. calculation absorptance rigorous diffraction theory allows prediction emissivity such structures. angle dependent...
Forest inventory data often provide the required base to enable largearea mapping of biomass over a range scales. However, spatially explicit estimates ofabove-ground (AGB) large areas may be limited by spatial extent theforest relative area interest (i.e., inventories not exhaustive), orby omission attributes for estimation. These andattributional gaps in forest result an underestimation areaAGB. The continuous nature and synoptic coverage remotely sensed have led totheir increased...
The value of combining Landsat time series and airborne laser scanning (ALS) data to produce regional maps forest structure has been well documented. However, studies are often performed over single study areas or types, preventing a robust assessment the approaches that most accurate estimates. Here, we use estimate attributes across six Canadian sites, which vary by type, productivity, management regime, disturbance history, with goal investigating spectral indices lengths yield estimates...
The renewed interest in thermophotovoltaic (TPV) energy conversion, based on recent progress materials and photovoltaic (PV) cell technology, requires a new evaluation of the TPV efficiency power density potential. In this paper, we address some important points system design. We proceed three steps, analyzing 1) thermodynamic limit, 2) an idealized, 3) realistic model, extrapolation current state technology. system, radiation converted to electricity is adapted spectral response PV cell....
The objective of this study was to determine whether a suite wood quantity and quality attributes balsam fir black spruce forests could be predicted using airborne laser scanner data. In situ estimates stand structure fibre were derived from measurements at sample plots covering wide range forest conditions insular Newfoundland. Models developed predict field explained 52–90 per cent the variation in attributes, including mean quadratic diameter breast height, average dominant stem density,...
Airborne laser scanner (ALS) data are used to map a range of forest inventory attributes at operational scales. However, when wall-to-wall ALS coverage is cost prohibitive or logistically challenging, alternative approaches needed for mapping. We evaluated an indirect approach extending ALS-based maps using medium resolution satellite and environmental data. First, we developed models predicted suite 950 km2 study area covered by Then, samples extracted from the predictions model these with...
Airborne laser scanning (ALS) has emerged as a technology capable of generating descriptors vegetation structure and best available terrain information. Research operational implementations ALS data have highlighted their value for characterizing forest spatially explicit objective spatial coverages mapping products management. Continued emphasis to enhance stewardship is promoting novel methods integrate detail non-timber ecosystem values like habitat, soil, water. Standardized criteria...
A method of estimating and mapping aboveground tree biomass (AGTB) was developed using provincially available forest inventory databases. More specifically, AGTB conversion tables were devised to estimate for stand attributes that are commonly mapped in provincial inventories over the Canadian landscape, i.e., species composition, projected crown density, dominant height. is first estimated at level allometric relationships measured stem distributions subsequently summed plot-level biomass....
