This paper proposed a geological segmentation algorithm to segment different geology, such as rivers, woodlands, and soil, etc. according on differences image feature of geology for aerial photography. In this paper, aerial image capture from low-flying quadcopter unmanned aircraft vehicle (UAV). Using Fuzzy-C-Mean method for aerial image color classification, and estimate some dominant colors of...
Geospatial technique, statistical analysis and in-situ sampling were coupled to explore the relationship between landscape patterns measured at both landscape and class level influence water quality in the 21 headwater sub-watershed within the Jiulong River watershed, Southeast China. The results show that water quality parameters selected are closely associated with both composition of land use types...
This paper aims at revealing how land use and land cover change in a subtropical coastal watershed of Southeast China, which has enormous influence on the region's economic and ecological health. Land sat Thematic Map per satellite imagery of 1986, 1996 and 2007 were used to create maps of each time point for 6 land categories. The results show that Built increased while Agriculture shrunk from 1986...
Impervious surface areas (ISA) play an important role in determining the water quality of the receiving waters. Remote Sensing, Geographical Information System, and multiple regression techniques were coupled in this study to detect the impervious surface area dynamics over the last 20 years and the linkage between ISA and Chemical permanganate index (CODMn), Ammonia (NH4+-N), and total phosphorus...
Every year since 2003, algae bloom has broken out in the branch bay of the Three Gorges Reservoir in Spring. The area affected by the algae bloom is often subject to disturbance which resulting from shipping, storm-runoff event, water conservancy scheduling and wind-wave etc. With its focus on effect of the disturbances on algae growth, this paper took the Xiangxi River Bay as an example. Water was...
