Raw interpolation surfaces

All interpolated surfaces and error data compressed as .zip archives. Must be first uncompressed and then opened in R using readRDS()

These surfaces were interpolated as part of the research paper, "Linear modelling: optimising interpolation for a LiDAR-based volumetric investigation into the construction of Iron Age and early medieval linear earthworks in England"

所有插值曲面及误差数据均以.zip归档形式压缩。需首先进行解压缩，然后使用R语言的readRDS()函数在R环境中打开。这些曲面作为研究论文《线性建模：优化插值以实现基于激光雷达的英国铁器和早期中世纪线性土堤体积调查》的一部分进行插值。
