Extracting Topographic Features From Shuttle Radar Topography Mission (SRTM) Images

This report addresses the problem of extracting topographic features from Shuttle Radar Topography Mission (SRTM) imagery. The features are used for Earth science applications and include slope, curvature, aspect, flow direction, flow accumulation and compound topographic index (CTI). The objective of our work is (1) to support topographic feature extraction similar to the one in ArcGIS, (2) to...

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...

Accuracy Assessment of Global Topographic Data (srtm & Aster Gdem) in Comparison with Lidar for Tropical Montane Forest

Shuttle Radar Topographic Mission (SRTM) and ASTER Global Digital Elevation Model (GDEM) provide topographic data in a global scale which are freely available for users. The potential use of these datasets for many forestry applications is highly depending on the accuracy of the datasets. In this study, we evaluated the accuracy of SRTM and ASTER GDEM version 2 with high accuracy topographic da...

Hepatic steatosis associated with microsporidiosis in teleost fishes from Marajó Island, Brazil.

A total of 40 specimens of the teleost fish Gobioides grahamae Palmer & Wheeler, 1955 were obtained from the municipality of Salvaterra on Marajó Island in the Brazilian state of Pará. Their livers were removed and processed for light microscopy. Overall, 90% of the specimens presented some degree of steatosis of the liver, which was invariably associated with the presence of Microsporidium sp....

Extraction of process-based topographic model units using SRTM elevation data for Prediction in Ungauged Basins (PUB) in different landscapes

The concept of this research is justified to the integration of landscape components for hydrological modelling within distributed models. Distributed models are based on homogeneous entities which are delineated using landscape parameters such as topography, land use, soil, and geology. In ungauged basins most of these required data are only available on a coarse spatial resolution. In order t...
