Spatial Query Processing in Geographic Database Systems
In this pupcar, we propose U spaliul qwrv languagt., called GSQL, to hurdle complex spatial olvects such us points, lines, rectangles, or polygons. To implemcvtt the ypatiul operutors such JS nearest, furthest, intersect, CO ver, adjacent-to, end-at, and distance. we present U two-phase query processing technique ionwt ing of a filter phase urd a refinement phase. The filter phase i s h u e d o...
متن کاملA Review of the Three-dimensional Field Displacement Retrieval Methods Using Interferometric Synthetic Aperture Radar Observations (InSAR) With Emphasis on the Precision of Each of these Methods
Interferometric Synthetic Aperture Radar (InSAR) technology provides a useful tool for quantitatively measuring the deformation of the earth, influenced by natural factors (earthquake, subsidence, and landslide) and human factors (construction of structures, drilling, and the overexploitation of underground water aquifers). In this context, time-series analysis of radar images allows the monito...
متن کاملThree-Dimensional Image of A Communicating Uterus
Recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(ART) (1). Gradually, the important role of three-dimensional (3D) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).
متن کاملThree-dimensional Localization of Nano-emitters with Nanometer-level Precision
We show nanometer-level localization accuracy of a single quantum-dot in three dimensions by self-interference and diffraction-pattern analysis. We believe that this approach has the capacity to push optical microscopy to the molecular level. ©2009 Optical Society of America OCIS codes: (180.2520) Fluorescence microscopy; (260.3160) Interference; (100.6640) Superresolution The use of fluorescen...
متن کاملUsing a Three Dimensional Spatial Database to Orthorectify Automatically Remote Sensing Images
Following SPOT5 launch, Spot Image and French National Geographic Institute (IGN) have decided to design a worldwide accurate database called Reference3DTM using data from the High Resolution Stereoscopic SPOT5 instrument (HRS). This database consists in three information layers : Digital Elevation Model at 1 arc.second resolution, Orthoimage at 1/6th arc.second resolution and Quality Masks ; w...
