Applying Digital Photogrammetry to Spatial Distribution of Debris Variation
Photogrammetry Debris Variation Geographic Information System (GIS)
2015/12/18
This study applies original aerial photographs to reconstruct orthoimages and extract digital terrain model (DTM) for images of various periods. The area of research is located at the Daluowan stream ...
MONITORING IONOSPHERIC VARIATION FOR A DEFINITE PERIOD TIME IN TURKEY
Ionosphere Total Electron Content GNSS
2016/1/15
Ionosphere has been studied by a number of scientists in recent years. Since GPS observations cannot provide TEC value directly, it can be estimated from combination of observations. In this study TEC...
URBAN LAND COVER AND SPATIAL VARIATION OBSERVATION USING ASTER AND MODIS SATELLITE IMAGE DATA
ASTER landscape metrics urban analysis land cover
2015/7/30
Land cover and land use changes associated with urbanization are important drivers of local geological, hydrological, ecological,
and climatic change. Quantification and monitoring of these changes ...
NOCTURNAL MONITORING OF THE LAND SURFACE TEMPERATURE VARIATION IN THE RIO GRANDE DO SUL STATE USING AVHRR/NOAA SATELLITES
Climate Retrieval Surface Temperature Temporal Observation AVHRR/NOAA
2015/7/29
The surface temperature is the net result of the climatic energy balance to the environmental process at the Earth. Therefore, accurate
estimation of land surface temperature (LST) can be regarded a...
SEASONAL VARIATION OF LAND COVER CLASSIFICATION ACCURACY OF LANDSAT 8 IMAGES IN BURKINA FASO
Phenology Classification Random Forest
2015/5/6
In the seasonal tropics, vegetation shows large reflectance variation because of phenology, which complicates land cover change monitoring. Ideally, multi-temporal images for change monitoring shoul...
Wavelength-dependent spatial variation in the reflectance of ‘homogeneous’ ground calibration targets
Spectral reflection characteristic of remote sensing data and the ground measurements
2015/2/5
Remotely sensed data are most useful if calibrated to spectral reflectance of known features. One
simple method of calibration is regression of remote data on the reflectance of several ground
targe...

ADVANCING ENVIRONMENTAL NOISE POLLUTION ANALYSIS IN URBAN AREAS BY CONSIDERING THE VARIATION OF POPULATION EXPOSURE IN SPACE AND TIME
Environmental noise Population exposure Spatial analysis Dasymetric mapping Lisbon
2014/4/24
Ambient noise is a subtle form of pollution in large urban areas, degrading human health and well-being. In Europe, directives
require that urban environmental noise be measured and mapped for the ...
