We present an algorithm for transformation and reconstruction of nautical charts, based on identification of common points in new orthophotos and old charts. The algorithm shows to be implementa...
Curvelet transformation proposed in 1999, on the basis of wavelet transformation, is a new multi-scale geometric analysis method. Besides scale parameter and location parameter, it adds an azimuth par...
GIS databases often need to include maps from diverse sources. These can differ one another by many characteristics: different projections or reference systems, (slightly) different scales, etc. Theor...
A new approach for hybrid matching based on polynomial models is proposed. Polynomial plays a key role in matching process; while the Efficiency Index measures the accuracy of the matching result. A...
The successful lunch of IKONOS and QUICKBIRD, and a serious of plans for acquiring the remote sensing images with high resolution let it become possible that the basic spatial information is obtaine...
We address the problem of semantic geodata translation in a file-based data sharing environment. By Semantic translation, we mean the translation process that can resolve semantic heterogeneity betwee...
The increasing population and economic activities are putting pressure on the available land resources. Human population and their use of land have transformed the terrestrial biosphere into anthropog...
The paper presents some considerations on the estimation of rigid-body transformation which is the basis for registration and georeferencing in terrestrial laser scanning. Two main issues are afforded...
