The work presents air quality impact assessment for the planned Municipal Solid Waste Incineration (MSWI) plant in Krakow with a established capacity of 255000 tons per year. The evaluation is based on assumption that air pollutant emissions from the incinerator will be at the highest allowed level resulting from emission limit values for waste incineration plants with operation time each of two planned lines 7500 hours per year. Calculation results for the one of the considered localization of the MSWI plant in Krakow (district of Nowa Huta) support the thesis that building the incineration plant of this size will not …

Digital Elevation Accuracy And Grid Cell Size: Effects On Computed Topographic Attributes, Rob H. Erskine, Timothy R. Green Dec 2006

Digital Elevation Accuracy And Grid Cell Size: Effects On Computed Topographic Attributes, Rob H. Erskine, Timothy R. Green

Timothy R. Green

Terrain attributes are commonly used to explain the spatial variability of agronomic, pedologic, and hydrologic variables. The terrain attributes studied here (elevation, slope, aspect, and curvature) are estimated readily from digital elevation models (DEMs), but questions remain about how the accuracy and sample spacing of the elevation data affect the estimated attributes. The main objective of this study was to quantify differences in each terrain attribute due to factors affecting DEM accuracy and grid cell size. Three data sources were compared: (i) real-time kinematic global positioning system (RTKGPS); (ii) satellite-differentially corrected global positioning system (DGPS); and (iii) U.S. Geological Survey …
