摘　　要：以高分二号国产卫星影像数据为实验对象,选取额敏县和乌恰县两个试验区,采用多种控制点布设方法,利用PCI遥感影像处理软件,对其纠正结果进行验证,提出满足1∶10 000测绘精度需求的控制点布设方案,为更高效率地完成1∶10 000基础测绘任务提供理论依据。This paper takes the GF-2 satellite image as the experimental object,selects Emin County and Wuqia County as the test ar-eas,adopts a variety of control points laying methods,and uses PCI remote sensing image processing software to verify the correction results.A control point layout scheme to meet the needs of 1∶10000 surveying and mapping accuracy is proposed to provide a theoreti-cal basis for 1∶10000 basic surveying and mapping tasks completed more efficiently.
