The Effect of Digital Elevation Model Resolution on Wave Propagation Predictions at 24Ghz
Digital Elevation Models (DEMs) are computer-generated representations of the earth's surface. These surfaces can be used to predicted Line-of-Sight (LOS) radio propagation. DEM resolution can affect the results of this prediction. This study examines the effect of DEM resolution on accuracy by …

Assessment of SWAT to Enable Development of Watershed Management Plans for Agricultural Dominated Systems under Data-Poor Conditions
… to input parameters, specifically soils and high resolution digital elevation models, which are likely to be lacking in data-poor environments, was quantified using Monte Carlo simulation. Two sources of soil parameter values (SSURGO and STATSGO) were investigated, as well as three levels of DEM …

Remote sensing for geomorphic and hydrodynamic modeling and process understanding
… used to accurately represent terrain at various resolutions in a hydrodynamic model (Chapter 2), characterize and understand dunefields along the Colorado River in the Grand Canyon in relation to geomorphic variables (Chapter 3), and lastly estimate river discharge from radar satellite …

Comparing Rusle LS Calculation Methods across Varying DEM Resolutions
… were compared across digital elevation models (DEMs) of 1, 5, 10, and 30m resolutions. This study rectifies the lack of direct and consistent testing OF these methods across multiple sites and DEM resolutions.</p> <p>The CA method produces higher mean, median, and max values of L than the GC …

Improved Environmental Characterization to Support Natural Resource Decision Making: (1) Distributed Soil Characterization, and (2) Treatment of Legacy Nutrients
… to evaluate the potential that different resolution digital elevation models (DEMs) have to distribute soil characteristics successfully. These studies are conducted in southwest Virginia and western Vermont. The aforementioned studies evaluated 36 and 59 soil samples, respectively. …
