GPlates 可视化化石点的运动轨迹,但化石点运动轨迹的坐标计算过程并不展现。目前,rgplates (R语言包) 基于 GPlates Web Service 提供了化石坐标点计算的 reconstruct 函数。
GPlates Web Service,即 GPlates 的 API,是官方提供的包含板块重建和坐标点重建相关接口。
这里首先介绍与坐标点重建计算相关的API接口。
原始内容请查看:
https://gwsdoc.gplates.org/reconstruction/reconstruct-points/
根据重建模型将现今的地理坐标点重建至古时的位置或相反。根据选择的重建模型(板块运动模型),每个坐标点会自动分配有一个板块id,随后计算期望的时间点时该坐标点的古坐标点(或古坐标点的现今坐标点)。
