摘要
利用美国Landsat-5夏末时相的TM-CCT数据,经计算机处理,外拍成像的TM图像,采用简化的目视综合解译法,专题解译稻田信息,其结果的定性解译正确率为93.9%,宏观面积精度为99.5%,从而明确了只要有合适的TM资料,那么,对平原稻区的县级以上的水稻遥感估产稻田面积进行监测是可能的。
The TM image was taken from the screen, while the TM-CCT data of Landsat-5 at the end of summer was treated by computer. Comprehensive interpretation with eye was adopt to interpretate the rice field information from the TM image. The accuracy of qualitative interpretation was 93. 9%; the accuracy of rice area estimate was 99. 5%. Therefore, if we have suitable TM data, the monitor of rice area for rice yield estimation by Remote Sensing in the plain rice cultivation area above is feasible.
