| 摘 要： | 目的以宝鸡市金台、渭滨两区为例,利用2004年6月ETM＋遥感影像进行土地利用/土地覆盖信息提取研究。方法在遥感技术和地理信息系统技术支持下,对遥感影像各波段进行特征分析的基础上,确定最佳波段组合,采用监督分类中的最大似然分类法结合人机交互解译相结合的方法完成土地利用类型信息的提取。结果通过对分类精度进行评价,结果表明该方法的有效性。结论利用遥感影像快速、定量地提取土地利用信息的方法是进行区域土地利用监测及数据更新的有效手段。

| Abstract: | Aim Taking the Jintai and Weibin Districts of Baoji City as an example,carried out the study of land use and land cover information extracting using June 2004 landsat image.Methods By using RS and GIS,the optimal bands was combined based on the statical characteristic analysis of each band.Land use types interpretation was finished with Maxiumum Likelihood Classification of surprised classification and human-computer interaction interpretation.Results Through the accuracy assessment of classification,the results show that the approach is effective.Conclusion The remote image land use information extracting ways which is frequent and mensurable is an effective method to supervise land use change and to renew data. |
