摘要
分析了扫描地形图产生误差的原因,提出了一种分条策略与完整的三次多项式校正方法相结合的误差校正方法,试验表明其优于完整的三次多项式的一次性校正方法,校正结果满足了实际需求。
For meeting the practical requirement, on the base of the analysis of error causes related to scanned topographic map, the common methods for map correction are introduced, and one error correction method which integrates zone strategy and cubic convolution is propsed. The case study showed that the proposed method was prior to the single cubic convolution method, and its result met the requirements.
