High-resolution digital 3D models of Algar do Penico Chamber: limitations, challenges, and potential

Effects of Digital Elevation Models (DEM) Spatial Resolution on Hydrological Simulation

Digital Elevation Model is one of the most important data for watershed modeling whit hydrological models that it has a significant impact on hydrological processes simulation. Several studies by the Soil and Water Assessment Tool (SWAT) as useful Tool have indicated that the simulation results of this model is very sensitive to the quality of topographic data. The aim of this study is evaluati...

Automatic Generation of High Resolution Urban Zone Digital Elevation Models

treating refractory hypertension: renal denervation with high-resolution 3d-angiography

a 53-year-old male was referred to our department for refractory primary hypertension. despite high doses of 6 anti-hypertensive drugs, ambulatory monitoring of blood pressure (bp) revealed a mean bp of 160/90 mmhg. under local anaesthesia, renal denervation with radiofrequency was performed supported by high-resolution 3d angiography, which helped confirm the position of the applications in a ...

High-resolution Satellite Imaging for Digital Surface Models

Elevation information is an important component of any geospatial database. It is imperative for applications such as topographic mapping, spatial and temporal change detection, feature extraction and visualisation. Although elevation data may in cases be purchasable from government agencies, the availability of alternative sources of data, such as space imagery, coupled with increased user con...

How Well Do High Resolution Models Represent Tropical Convection?

Cascade is a multi-institution project studying the temporal and spatial organization of tropical convective systems. While cloud resolving numerical models can reproduce the observed diurnal cycle of such systems they are sensitive to the chosen resolution. As part of this effort, we are comparing results from the Met. Office Unified Model to data from the Global Earth Radiation Budget satelli...
