Digital Elevation Models (DEMs) have been increasingly used to model the terrain surfaces to provide the 'physical bases' for environmental studies. However, DEM is subject to systematic errors, rando...
Digital Elevation Model (DEM) is indispensable for many analyses such as topographic feature extraction, runoff analysis, slope stability analysis and so on. Beforehand such analyses, accuracy of DEM ...
Various methods of analysis and dataset have been used for urban studies. However, used urban data often has low spatial resolution,especially regional statistics, though statistical data can cover la...
The paper presents the use of tablet pc in archaeology, it explains what is a tablet PC and the steps to draw archaeological remains using a digital photomosaic. It’s described the test made during th...
This paper is continuation work of a research started in 2005. In the previous research, variety of fuzzy digital elevation models was constructed and the best fit model was selected in order to prese...
airborne digital imagers: an overview & analysis.
In this work, a theoretical-empirical model has been developed for the modelling of the local geometric accuracy of digital orthoimages from panchromatic QuickBird Very High Resolution Satellite Image...
The accuracy of object reconstruction was tested with two medium format cameras made by ALPA of Switzerland. Both cameras have been equipped with a 33 megapixel Leaf Aptus 75 digital camera back and a...
A great number of papers have been so far published about the comparison and the integration between terrestrial laser scanning and digital photogrammetry, as surveying and 3D modeling techniques. Tho...
Digital hydrogeological map spatial data base is the most important components of “digital China ”. According to uniform standard,primary hydrogeological materials were converted into numeric format t...
Since the early days of the first Earth monitoring satellite launches, the ability to distribute these important data resources to the world community has been especially challenging. This chronic sh...
The High Resolution Stereo Camera (HRSC) on board of the European space mission Mars Express provides multispectral digital image data in high resolution as well as the systematic stereo coverage of ...
The U.S. Geological Survey has recently completed a final revised version of its 231 m/pixel global Viking image mosaic of Mars that has substantially improved geodetic accuracy compared to versions ...
In many cases, the derivation of high-resolution digital terrain models (DTMs) from planetary surfaces using only conventional digital image matching is a problem. The matching methods need at least ...
Digital Elevation Models (DEM) generated by automatic image matching of high resolution space images are used often for very high resolution orthoimage production. The published accuracies of such DE...
