The paper presents an approach for the generation of digital elevation models (DEMs) of underwater areas from aerial images. Standard software-products do not provide the possibility to measure correc...
The article describes the possibility of developing an overall map of the selected area on the basis of publicly available data. Such a map would take the form designed by the author with the colors t...
The National Science Foundation (NSF) and the National Geospatial-Intelligence Agency (NGA) have publicly released new three-dimensional topographic maps of Alaska in support of a White House Arctic i...
Usual workflows for production, archiving, dissemination and use of Earth observation images (both aerial and from remote sensing satellites) pose big interoperability problems, as for example: non-al...
The National Bureau of Surveying & Mapping of China has planned to speed up its development of spatial data infrastructure (SDI) in the coming few years. This SDI consists of four types of digital pro...
In the framework of the Shuttle Radar Topography Mapper (SRTM) Mission the generation of high-quality Digital Elevation Models (DEMs) with global coverage of the earth's surface is envisaged. In this ...
A workstation based user friendly system developement is followed for easy orthoimage product generation. The package is tested with several IRS-lC stereo data sets, over different terrains with vary...
SPOT-5 and Cartosat-1 are mapping satellites with high resolution and along-track stereo capability. This paper describes the work carried out towards the qualitative and quantitative comparison of t...
The fusion of digital surfaces, their optimal combination into a new single dataset, is a crucial topic in the geomatic sciences. Nowadays, sensors and processing techniques provide for the same site...
Digital elevation models (DEM) of high resolution and high quality are required for many applications like urban modeling, readiness for catastrophes or disaster assessment. A good source for the de...
There are two major freely available global digital elevation datasets, known as GTOPO30 and SRTM. To know the accuracies of those data in global scale, relative evaluation of these data and validatio...
The Great Wall is one of the biggest man-made wonders of the world! The wall consists of bricks made by different dynasties and built on thousands of kilometers of steep mountain terrain. It has many ...
A new DEM called Hybrid Mesh DEM (HM-DEM) with a hybrid mesh is put forth to improve the DEM’s capacity of representation of different kinds of micro-terrains and complex landscapes. The conceptual mo...
In this paper a new approach is presented to predict maximum wind speeds using Gradient Boosted Regression Trees (GBRT). GBRT are a non-parametric regression technique used in various applications, su...
The high-resolution satellite imageries (HRSI) are as primary dataset for different applications such as DEM generation, 3D city mapping, change detection, monitoring, and deformation detection. The g...
