为揭示东部高潜水位矿区地表水体的时空演变规律,该文以兖州煤田为研究区,在比较改进归一化差异水体指数法、单波段阈值法、谱间关系法、K-T变换4种水体提取方法的精度及优缺点基础上,采用基于阈值分割的改进的归一化差异水体指数法提取了研究区1990-2014年的水体信息并分析了其时空变化特征。研究结果表明:从1990-2009年,兖州煤田地表水域面积增加了1 696.14 hm2,且2001-2005年水...
Water information cannot be accurately extracted using TM images because true information is lost in some images because of blocking clouds and missing data stripes, thereby water information cannot b...
The accuracy of snow cover information extraction in remote-sensing images dependent on a variety of factors, especially in mountain area with complex terrain. This paper aims at analyzing the accurac...
Land desertification is one of the most important problems about the issue of environment, social and economy in the world. Vegetation category and quantity is a significant criterion to measure the e...
This study aims to determine the accuracy level at which different forms of land degradation can be mapped from medium-resolution satellite data, and to assess how accurately degraded land can be dete...
Remote sensing image fusion aims at integrating the information conveyed by data acquired with different spatial and spectral resolution from satellite and aerial platforms. Image fusion is a very imp...
The defection of single data source can be solved with fusion between TM and SAR images. It provides a better solution for land surface monitoring in the mining areas. Results of experiment showed tha...
In this paper,it gave a detailed introduction about the classification process of land use in Guangzhou supported by RS and GIS software using the data of Landsat TM of 1997 and 2003. After being geom...
Many global problems can be estimated and forecasted by remote sensing with its advantage of periodicity, objectivity and large scale scope, besides plant area estimation. Conventional classification ...
In this thesis, we build a relationship between Remote Sensing information and water depth to calculate and analyze the elevation of the riverbed. Combining with the water level elevation data, we can...
This research simulates the urban growth and therefore the landscape change of a mountain city of Chongqing, China through a Cellular Automata (CA) based model of SLEUTH. The fundamental data were fou...
In recent years the launch of (very) high-resolution (VHR) spaceborne multi-spectral (MS) scanners has made purely supervised remote sensing (RS) image analysis over extended target areas no longer ...
The study of the land cover is one of the most important factors for planning and managing activities concerning the use of land surface on this earth. Remote sensing techniques have improved mappin...
The Mongolian territory includes various ecosystems as, taiga forest, high mountains, width steppe and gobi desert, through North to South. The glacier is most important land cover type to keep the ...
East Oweinat district is located in the south Western Desert of Egypt. It is mainly occupied by outcrops of Archean to Early Proterozoic rocks of high to medium metamorphic grade and younger granitoi...
