- 摘要:
- 选取同一地区的TM、SPOT5(2.5 m)和SPOT5(10.0 m)3种不同数据源,利用目视解译的方法来解译大豆种植面积,以GPS实测面积为真值,通过对比3种数据源大豆解译面积与实测面积的误差,来计算不同数据源的解译精度。结果表明:3种数据源相比较,SPOT5(2.5 m)无论是在单个样地解译误差率还是总误差率上都最有优势,但考虑价格及应用因素,在保证精度的前提下,TM数据更有实用价值。
- Abstract:
- Choosing three different data source of TM, SPOT5(2.5 m) and SPOT5(10.0 m), using visual interpretation method, the interpretation precision of the three data sources were calculated by comparing the error between the interprated area and the real area based on GPS.The result that SPOT5(2.5 m)had advantages on single sample interpretation error rate and total error rate.But the TM data had more utility value on the premise of guaranteed precision because of price and application factor.
