Doctoral Dissertation Research: Land-Cover Change Detection for the Tropics Using Remote Sensing and Geographic Information Systems

简·路易斯安那州立大学在哥斯达黎加东北部的土地覆盖变化探测将提供人类对热带森林环境影响的时空数据。目的是确定人类活动对土地覆盖的原因和影响，并确定一种利用遥感和地理信息系统(地理信息系统)探测研究区域当地土地覆盖变化的方法，该区域由赫雷迪亚省的两个保护区组成。利用1970年至1990年三个日期的陆地卫星数据使用选定的遥感/地理信息系统方法，将在基地机构和实地进行。将对照从实地观察、航空照片、地图和文献资料中得出的变化图，对根据这些分析编制的变化图进行量化评估。这项研究将增进对用于评估热带森林环境中土地覆盖变化探测的标准遥感/地理信息系统技术的性能和准确性的了解。它还将扩大我们对全球范围内人类对环境影响的了解。

Read, Jane Louisiana State University Land-cover change detection in northeastern Costa Rica will provide spatio-temporal data of human impacts on a tropical forest environment. The objectives are to identify causes and effects of human activities on land cover and identify a method using remote sensing and geographic information systems (GIS) to detect local land cover changes in the study area, which comprises two protected areas in the province of Heredia. The use of selected remote sensing/GIS methods using Landsat data for three dates from 1970 to 1990 will take place at both the base institution and in the field. Change maps developed from these analyses will be quantitatively assessed against change maps derived from field observations, aerial photographs, maps and literature sources. The study will improve understanding of the performance and accuracies of standard remote sensing/GIS techniques for assessing land cover change detection in tropical forest environments. It will also enlarge our knowledge of human impacts upon the environment in a global context.
