The following details are shown: (a) DEM resolution has a significant effect on slope estimation: the average slope becomes smaller and the standard deviation becomes larger when DEM resolution changes from fine to coarse, and the different impacts of DEM resolution on different slope ranges can be classified into three gradient classes: 0-10° (underestimated slope), 10-35° (overestimated slope), and >35° (little impact on slope estimation) (b) DEM resolution has little effect on aspect estimation, but flat areas become larger when DEM resolution changes from fine to coarse and (c) the quantity of hydrologic topography information declines as DEM resolution decreases. The results show that: (1) DEM is a very effective tool for terrain analysis: many terrain attributes (such as slope, aspect, slope type, watershed, and standard flow path) can be derived, and these attributes can be displayed with both image and attribute databases, with the help of GIS (2) DEM resolution has a great influence on terrain attributes.
NANO DIGITAL TERRAIN MODEL SOFTWARE
The Hayachinesan mountain area (in northeastern Japan) was chosen as research site, and the focus was on terrain analysis and the impacts of DEM resolution on topographic attributes, analyzed using TNTmips GIS software (MicroImage, Inc., USA) and “Digital Map 25,000” (published by the Geographical Survey Institute of Japan in 1998). This study analyzed digital elevation data sources and their structure, the arithmetic of terrain attribute extraction from DEM and its applications, and DEM’s error and uncertainty algorithm. DEM has been applied to physical geography, hydrology, ecology, and biology. The load capacity of your unit is designated by weight, not by volume, so you cannot necessarily use all available space when loading your unit.The digital elevation model (DEM), an important source of information, is usually used to express a topographic surface in three dimensions and to imitate essential natural geography. A label identifying the unloaded vehicle weight of the actual unit and the cargo carrying capacity is applied to every Coachmen RV prior to leaving our facilities. **Estimated Average based on standard build optional equipment.Įach Coachmen RV is weighed at the manufacturing facility prior to shipping. Available CCC should accommodate fresh potable water (8.3 lbs per gallon).īefore filling the fresh water tank, empty the black and gray tanks to provide for more cargo capacity. *Estimated Average based on standard build optional equipment.ĬCC (Cargo Carrying Capacity)** - is the amount of weight available for fresh potable water, cargo, additional optional equipment and accessories.ĬCC is equal to GVWR minus UVW. The UVW does not include cargo, fresh potable water, additional optional equipment or dealer installed accessories. It includes all weight at the unit’s axle(s) and tongue or pin and LP Gas. UVW (Unloaded Vehicle Weight)*- is the typical weight of the unit as manufactured at the factory. GAWR (Gross Axle Weight Rating) – is the maximum permissible weight, including cargo, fluids, optional equipment and accessories that can be safely supported by a combination of all axles.
