As humans are the primary geomorphic agents on the landscape, it is essential to assess the magnitude, chronological span, and future effects of artificial ground that is expanding under modern urbanization at an alarming rate. We argue humans have been primary geomorphic agents of landscapes since the rise of early urbanism that continue to structure our everyday lives. Past and present anthropogenic actions mold a dynamic "taskscape" (not just a landscape) onto the physical environment. For example, one of the largest Pre-Columbian metropolitan centers of the New World, the UNESCO world heritage site of Teotihuacan, demonstrates how past anthropogenic actions continue to inform the modern taskscape, including modern street and land alignments. This paper applies a multi-scalar, long durée approach to urban landscapes utilizing the first lidar map of the Teotihuacan Valley to create a geospatial database that links modern and topographic features visible on the lidar map with ground survey, historic survey, and excavation data. Already, we have recorded not only new features previously unrecognized by historic surveys, but also the complete erasure of archaeological features due to modern (post-2015) mining operations. The lidar map database will continue to evolve with the dynamic landscape, able to assess continuity and changes on the Teotihuacan Valley, which can benefit decision makers contemplating the stewardship, transformation, or destruction of this heritage landscape.

人类作为地貌代理：墨西哥特奥蒂瓦坎山谷的过去、现在和未来的激光雷达检测。

由于人类是景观的主要地貌因素，因此必须评估在现代城市化下以惊人速度扩张的人造地面的规模、时间跨度和未来影响。我们认为，自早期城市主义兴起并继续构建我们的日常生活以来，人类一直是景观的主要地貌代理人。过去和现在的人为行为在物理环境中塑造了一个动态的“任务景观”（不仅仅是景观）。例如，新世界最大的前哥伦布大都市中心之一，联合国教科文组织世界遗产特奥蒂瓦坎，展示了过去的人为活动如何继续为现代任务场景提供信息，包括现代街道和土地路线。本文采用多标量，使用特奥蒂瓦坎山谷的第一张激光雷达地图创建一个地理空间数据库，将激光雷达地图上可见的现代和地形特征与地面调查、历史调查和挖掘数据联系起来，对城市景观进行长期的研究。我们已经不仅记录了历史调查以前无法识别的新特征，而且还记录了由于现代（2015 年后）采矿作业而完全消除的考古特征。激光雷达地图数据库将随着动态景观不断发展，能够评估特奥蒂瓦坎山谷的连续性和变化，这可以使考虑管理、改造或破坏这一遗产景观的决策者受益。
