基于五年已进行过辐射校正及几何校正的多伦多地区Landsat5-TM影像数据,利用ENVI5.1软件进行遥感影像处理与土地利用信息提取,分析了1992~2010年间多伦多市的耕地、植被覆盖、水域等生态用地的变化特征及其影响因素,为其他大都市的生态宜居城市建设提供参考和借鉴。
This study uses Landsat5-TM image data for Toronto,which was corrected for both radiation and geometry,and ENVI5.1software for remote image processing and extracting information regarding land use.Using this technology,the study analyzes the variations of cultivated land,vegetation cover,water,and other ecological land and the reasons for this variation in Toronto during1992-2010.The data provides a resource for other metropolises engaging in livable city construction.
