Identification of heat transfer type is essential to geothermal exploration and reservoir mapping because thermal conductivity in water is relatively lower than in average rock materials. This study focused on mapping the two types of heat transfer in the shallow crust, conduction and convection, from a set of temperature-logging dataset, temperature gradient, thermal conductive, and volcanoes data...
Due to increasing global demand for natural rubber products, rubber (Hevea brasiliensis) plantation expansion has occurred in many regions where it was originally considered unsuitable. However, accurate maps of rubber plantations are not available, which substantially constrain our understanding of the environmental and socio-economic impacts of rubber plantation expansion. In this study, the rubber...
Uncertainties from aerosol type greatly affects the accuracy in water color remote sensing for case II waters. An algorithm, depicted as ACCIA, dedicated to define the aerosol types over case II waters is developed by iterating the four critical component concentrations in an aerosol type: dust like, water soluble, oceanic and soot. A software function module is also developed in Visual Studio 2010...
Crop planting area is significant to agricultural structure adjustment and regional food balance policy. Based on field investigation and spectral property analysis of corn in HJ1-CCD images, different threshold configurations are set to build decision trees and corn planting area is precisely extracted utilizing multi-temporal HJ-1 CCD images in Zhecheng county, Henan Province of China. Both statistical...
The Wenchuan earthquake was a destructive earthquake that measured at 7.9 Mw occurred at 14:28:01.42 CST on May 12, 2008 in Sichuan province of China, which induced large quantities of secondary mountain disasters such as collapse, landslides, debris flows and barrier lakes. These disasters occurred and more seriously formed disaster chains causing great destruction, and costing many lives after both...
The method of hyperspectral remote sensing has great potential in the area of offshore oil and gas exploration and marine pollution investigation. Combined with Hyperion hyperspectral satellite images and the surface geochemical data of dissolved hydrocarbons at Liaodong Bay, as well as the concentration data of chlorophyll and suspended material, The distribution of hydrocarbon over Liaodong Bay...
Using EOS-Terra/MODIS in 2005-2007 to retrieve aerosol optical depth, spatial and temporal variations of aerosol optical depth in Chongqing was studied. The results show that the monthly distribution is characterized by double peak and double valley. The peak values appear in April, secondary peak in September, the minimum value in November and the other valley value in August. Seasonal change of...
Inverse Synthetic Aperture Radar (ISAR) is used to image noncooperative moving targets such as aircrafts, ships and celestial objects. The target rotation relative to the radar is the source for obtaining cross-range resolution in ISAR imaging. In airborne ISAR imaging of ships, the composition of the relative motion is more complicated than in other cases. One component is produced by the relative...
