Comparison of Digital Elevation Models for Aquatic Data Development
Thirty-meter digital elevation models (DEMs) produced by the U.S. Geological Survey (USGS) are widely available and commonly used in analyzing aquatic systems. However, these DEMs are of relatively coarse resolution, were inconsistently produced (i.e., Level 1 versus Level 2 DEMs), and lack drainage enforcement. Such issues may hamper efforts to accurately model streams, delineate hydrologic un...
متن کاملa new approach to credibility premium for zero-inflated poisson models for panel data
هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...
15 صفحه اولA New Data Structure for Refined Digital Elevation Models
A new DEM called Hybrid Mesh DEM (HM-DEM) with a hybrid mesh is put forth to improve the DEM’s capacity of representation of different kinds of micro-terrains and complex landscapes. The conceptual model of HM-DEM and its data structure, namely Hybrid Mesh Data Structures (HMDS) are also put forth and discussed in details. The HMDS is encapsulated into an object called HmDem which is comprised ...
متن کاملComparison of digital elevation models of alpine glaciers
Glaciers are indicators of the global climate change. The change in the extent and volume of a glacier can be estimated from digital elevation models (DEMs) produced from remotely sensed spaceborne or airborne data using photogrammetric, interferometric, or laser scanning techniques. For this study, the most promising data sources available were selected and tested. The selected sites were two ...
متن کاملOptimization of Digital Elevation Models for Routing
Routing is a common task when using digital maps, but most engines offer only travel routes for automobiles. However, a more interesting aspect in this topic arises when being a cyclist. For this target audience especially elevation information is relevant. Such data is available from different sources, but is not perfectly usable for cycling routing. Those digital elevation models may include ...
