Three-dimensional mapping products in the form of DEMs (Digital Elevation Models) have become much more accessible in recent years, in part due to the implementation of LIDAR and IFSAR technologies. While there is considerable familiarity with one technology or the other, they are not often examined in terms of their mutually similar characteristics or equally those that are dissimilar. The pur...

S ubstantial intellectual and financial resources have been invested in the quest to reduce outcomes in patients with ST elevation myocardial infarction (STEMI) through improved pharmacological and mechanical reperfusion therapies. By contrast, little emphasis has been placed on enhancing the medical systems whereby these treatments are delivered, especially as it relates to pre-hospital reperf...

In processing raster digital elevation models (DEMs) it is often necessary to assign drainage directions over flats—that is, over regions with no local elevation gradient. This paper presents an approach to drainage direction assignment which is not restricted by a flat’s shape, number of outlets, or surrounding topography. Flow is modeled by superimposing a gradient away from higher terrain wi...

We present a system for modeling buildings from a single correlation-based Digital Elevation Model (DEM). The model is constructed in two stages. The first stage segments the DEM into planar surface patches that describe the building. The second stage generates the final polygonal model of the building using weak geometric constraints. We use robust estimation methods at different stages of our...

conclusions this study confirms that primary pci revascularization is the best treatment for the acute st elevation mi with brilliant acute result and one- year high survival and acceptable cardiac and non-cardiac complications. studying the effects of using des and bms on long term cardiac mortality, morbidity and need to target vessels revascularization (tvr) shows that performing the pci in ...

abstract limitations of traditional (conventional) soil surveys and improvement of information technology have lead soil surveyors to invent new methods which are generally called digital soil mapping (dsm). the aim of these methods is the prediction of soil classes or soil properties based on easily-available or measuring environmental variables. the objective of this investigation is to study...

Relief relative to a local elevation maximum provided a strong indicator of inundation dynamics (i.e., hydroperiod), but was less useful for mapping wetland boundaries. Combining local relief and an Enhanced Topographic Wetness Index produced a map that was well suited for mapping wetland extent and hydroperiod. Wetlands mapped using aerial photographs or LiDAR-derived digital elevation models ...
