Tectonic plate motion affects coordinates resulting from GPS measurements and the referencing of aerial and satellite imagery. It therefore impacts the long-term use of global coordinate systems. Over time, the tectonic plates move relative to each other and coordinates become outdated. Most geographic datasets including OpenStreetMap are no exception, as these are affected in terms of a growing location–coordinate mismatch. Current research is aware of this issue but solution strategies have not been fully explored yet. In this manuscript, we discuss how regular systematic updates of coordinate values can be used to address this issue. We explore the recommended frequency to perform such updates for guaranteeing a minimal loss of accuracy after long periods of time. It is further determined how rounding errors impair such systematic updates and in which ways singular and irregular manual updates impede systematic solution strategies. The solution strategies proposed lead to minimal overall errors and thus guarantee to retain high positional accuracy of coordinate pairs within global datasets, even after years of existence.

构造板块运动对地理参考长期全球数据集的影响

构造板块的运动会影响GPS测量以及航空和卫星图像参考的坐标。因此,它影响了全球坐标系的长期使用。随着时间的推移,构造板块彼此相对移动,并且坐标已过时。包括OpenStreetMap在内的大多数地理数据集也不例外,因为它们会随着位置-坐标不匹配的增加而受到影响。当前的研究已经意识到了这个问题,但是尚未完全探索解决方案策略。在本手稿中,我们讨论如何定期使用坐标值的系统更新来解决此问题。我们探索推荐的频率来执行此类更新,以确保经过长时间后将精度损失降至最低。进一步确定舍入错误如何损害此类系统更新,以及奇异和不定期的手动更新以何种方式阻碍系统解决方案。提出的解决方案策略可将整体误差降至最低,从而即使在存在多年之后,也可以保证在全局数据集中保持较高的坐标对定位精度。
