Survey of the Temple of the Sun, Machu Picchu with the Optech ILRIS-3D

The Temple of the Sun is a monument at the world-renowned archaeological site of Machu Picchu, in Peru. The structure is believed to be an astronomical observatory used to mark the winter solstice.

The Center for Advanced Spatial Technologies (CAST), University of Arkansas conducted high density surveys of the Temple of the Sun as part of a UCLA field school in 2009. During the field school, students acquired the 3D survey data while learning about different mapping and documentation standards. CAST researchers completed the additional data processing.

太阳神庙（Temple of the Sun）坐落于秘鲁举世闻名的考古遗址马丘比丘（Machu Picchu），为该遗址的一处古迹。学界普遍认为，该建筑曾作为天文观测台，用于标记冬至（winter solstice）。
2009年，阿肯色大学高级空间技术中心（Center for Advanced Spatial Technologies, CAST）作为加州大学洛杉矶分校（University of California, Los Angeles, UCLA）野外实习课程的组成部分，对太阳神庙开展了高密度测绘工作。参与本次实习的学生在学习各类测绘与文档记录规范的同时，采集了该建筑的三维测绘数据；高级空间技术中心的研究人员则完成了额外的数据处理工作。
