This paper explores the accuracy of Digital Elevation Models (DEMs), with particular reference to Australian published DEMs. Direct comparisons were made between cartometric and automatically measured photogrammetric DEMs at various grid spacings with an accurate and dense set of ground truth data. The cartometric DEMs were found to be more accurate than the photogrammetric DEMs for the small s...

To identify potential targets for the early treatment and prevention of gastric cancer, microRNA (miRNA) expression profiles of precancerous lesions of gastric cancer were investigated. The miRNA microarray dataset GSE24839 was downloaded from Gene Expression Omnibus (GEO) and included 10 Helicobacter pylori-related gastritis samples and 10 gastric intestinal metaplasia samples. Differentially ...

Nowadays, different sensors and processing techniques provide Digital Elevation Models (DEMs) for the same site, which differ significantly with regard to their geometric characteristics and accuracy. Each DEM contains intrinsic errors due to the primary data acquisition technology, the processing chain, and the characteristics of the terrain. DEM fusion aims at overcoming the limitations of di...

This study evaluates the accuracy of digital elevation models (DEMs) produced from Cartosat-1 data. The Cartosat-1 satellite, launched by the Indian Space Research Organization (ISRO) in May 2005, carries two panchromatic cameras capable of acquiring stereoscopic data along the orbital track. These data provide the potential to produce high-quality DEMs for virtually any location on the Earth’s...

The main aim of a research presented in this paper is selection of the most suitable interpolation method and its parameter settings for creation of digital elevation models (DEMs) of base types of relief in the Czech Republic (flatlands, hilly areas, uplands and highlands) from the DMÚ 25 database. The suitability of interpolation methods and their settings was explored using the assessment of...

Digital Elevation Models (DEMs) are widely used in many GIS and resource management applications. Increased use of DEMs has led to greater demand for higher resolution and higher accuracy digital elevation data. Here we demonstrate that digitally-scanned 1:40,000-scale NAPP aerial photography, used in conjunction with precision ground control, can be used to generate DEMs with horizontal resolu...
