Change of geographic information service model in mobile context
Geo-spatial Information Science - Tập 8 - Trang 269-275 - 2005
A research on that how the topic of mobility, which is completely different but tightly relevant to space, provides new approaches and methods so as to promote the further development of geographic information services, will accumulate basic experience for different types of relative information systems in the wide fields of location based services. This paper analyzes the meaning of mobility and ...... hiện toàn bộ

Discriminant models for uncertainty characterization in area class change categorization
Geo-spatial Information Science - Tập 14 - Trang 255-261 - 2011
Discriminant space defining area classes is an important conceptual construct for uncertainty characterization in area-class maps. Discriminant models were promoted as they can enhance consistency in area-class mapping and replicability in error modeling. As area classes are rarely completely separable in empirically realized discriminant space, where class inseparability becomes more complicated ...... hiện toàn bộ

Modified multispectral space for color representation
Geo-spatial Information Science - Tập 8 - Trang 306-310 - 2005
Conventional multispectral space for color representation is modified by algorithm of cluster analysis and principal component analysis. Results show that the newer modified multispectral space not only keeping the structure of the original space but eliminating zero-crosses as well its accuracy of color representation is higher than the conventional.
Combined GPS/GLONASS precise positioning for long-distance baselines
Geo-spatial Information Science - - 2001
Combined GPS/GLONASS can increase the accuracy and reliability of positioning especially in some applications with many impediments. Due to the atmosphere delay, the commonly used methods for processing short distance baselines can not be implemented in long distance baselines. In this paper, a new data processing strategy for long distance baselines is proposed, which uses the properties of some ...... hiện toàn bộ
The change of land use/cover and characteristics of landscape pattern in arid areas oasis: An application in Jinghe, Xinjiang
Geo-spatial Information Science - - 2010
This paper uses 3S technology in macroscopic. Combining the integrated technology of ecological quantity analytical method with GIS technology through ArcGIS and Fragstats, the authors study the images of 1972, 1990, 2001, and 2005 and obtained land use data in Jinghe County. Then, the change of land use/cover and landscape pattern had been analyzed in the Jinghe County of Xinjiang. The conclusion...... hiện toàn bộ
Method and application of comprehensive knowledge discovery
Geo-spatial Information Science - Tập 6 - Trang 48-55 - 2003
This paper proposes the principle of comprehensive knowledge discovery. Unlike most of the current knowledge discovery methods, the comprehensive knowledge discovery considers both the spatial relations and attributes of spatial entities or objects. We introduce the theory of spatial knowledge expression system and some concepts including comprehensive knowledge discovery and spatial union informa...... hiện toàn bộ
