Hyperspectral spectrometers can record electromagnetic energy with hundreds or thousands of spectral channels. With such high spectral resolution, the spectral information has better capability for ma...
The large number of bolts and screws that attached to the subway shield ring plates, along with the great amount of accessories of metal stents and electrical equipments mounted on the tunnel walls, m...
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 ...
Analyzing the law of economic development and estimating the regional economy development’s level to discover the relation between the economy development and area diversity, which can providethe refe...
The shape measurement of goaf is an important job in mine project. With the rapid development of the measuring equipment, 3D laser scanner, which makes the efficiency of traditional work being improve...
The physical based Li-Strahler geometric-optical model can be inverted to retrieve forest canopy structural variables. One of the main input variables of the inverted model is the fractional component...
Taking advantages of geo-spatial technology integrated with monitoring methods, and aiming at high-cut slope monitoring and management, this paper proposed a new concept of high-cut slope geo-spatial ...
As a non-profit, international, voluntary consensus standards organization, OGC and ISO/TC211 have been dedicating to develop standards for geospatial and location based services. WMS and WCS are two ...
As the Geospatial Technology (GT) grows, the generation and utilization of 3D city spatial model are actively studied. In some applications, the fundamental model is too detail comparing with the leve...
Based on cell complex theory, after analyzing the corresponding relationship among cell, cell complex and 3D spatial solid, a formal definition for 3D spatial solid is presented. Through analyzing the...
This paper takes the cloud model into land price information inquiry, using cloud model to express the spatial concept and the attributes of spatial entity described with qualitative language, it inte...
Monthly median empirical models IRI-95 and NeUoG were compared with incoherent scatter EISCAT and Millstone Hill observations as well as with El Arenosillo Digisonde N e (h) bottomside profiles. A com...
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...
Hourly values of the critical frequency of the ionospheric F region, foF2, obtained at Chongqing ionospheric observatory (geographic 29.50N, 106.40E), China, during the interval of 1977 to 1997 (solar...
We constructed a model of earthquakes (M ? 5.0) in Kanto, central Japan, based on three parameters: the a and b values of the Gutenberg-Richter relation, and the ?- parameter of changes in mean event ...
