Object-Oriented Change Detection Definiens Developer Rule Sets Riparian Zones
2015/11/16
The objectives of this research were to: (1) develop rule sets in Definiens Developer 7® for mapping and monitoring riparian zone
land-cover classes within two QuickBird images; and (2) compare...
IMAGE CLASSIFICATION WITH A REGION BASED APPROACH IN HIGH SPATIAL RESOLUTION IMAGERY
Image segments classification object-oriented approach
2015/6/1
A number of studies have been carried out to find an appropriate spatial resolution to which to aggregate data in order
to reduce the variation within an object, and minimize the classification erro...
High-spatial resolution U–Pb dating of phosphate minerals in Martian meteorite Allan Hills 84001
U–Pb dating phosphates NanoSIMS Martian meteorites ALH 84001
2017/4/11
Phosphate minerals, which are ubiquitous in terrestrial and extra-terrestrial rocks, are important carriers of trace elements,
including U and Th, which provide chronological information because of t...
THE GEOSPECTRAL CAMERA: A COMPACT AND GEOMETRICALLY PRECISE HYPERSPECTRAL AND HIGH SPATIAL RESOLUTION IMAGER
Hyper spectral multispectral georeferencing multiresolution camera
2014/4/24
Small unmanned aerial vehicles are increasingly being employed for environmental monitoring at local scale, which drives the demand for compact and lightweight spectral imagers. This paper describes t...
High spatial resolution monitoring of the activity of BA supergiant winds
High spatial resolution the activity BA supergiant winds
2011/1/13
There are currently two optical interferometry recombiners that can provide spectral resolutions better than 10000, AMBER/VLTI operating in the H-K bands, and VEGA/CHARA, recently commissioned, opera...
Massive and Refined. II. The statistical properties of turbulent motions in massive galaxy clusters with high spatial resolution
The statistical properties turbulent motions massive galaxy clusters
2011/1/13
We study the properties of chaotic motions in the intra cluster medium using a set of 20 galaxy clusters simulated with large dynamical range, using the Adaptive Mesh Refinement code ENZO (e.g. Norman...
High-spatial-resolution imaging of thermal emission from debris disks
circumstellar matter infrared stars – planetary systems
2010/11/11
We have obtained sub-arcsec mid-IR images of a sample of debris disks within 100 pc. For our sample of nineteen A-type debris disk candidates chosen for their IR excess, we have resolved, for the firs...
Observations of dusty torii and compact disks around evolved stars: the high spatial resolution IR view
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
The recent high angular resolution observations have shown that the transition between a globally symmetrical giant and a source surrounded by a spatially complex environment occurs relatively early, ...
A spatial resolution threshold of land cover in estimating terrestrial carbon sequestration in four counties in Georgia and Alabama, USA
land cover terrestrial carbon sequestration Georgia and Alabama, USA
2010/1/21
Changes in carbon density (i.e., carbon stock per unit area) and land cover greatly affect carbon sequestration. Previous studies have shown that land cover change detection strongly depends on spatia...
