Abstract This paper presents an experience developed in the Hualfin Valley (Catamarca, Argentina), aimed at testing the utility and suitability of non-invasive methods for documenting and analyzing sites of inconspicuous nature. The documentation of architectural remains and of archaeological materials with reference to them has been common fieldwork practice in this region. However, this produces a partial documentation of the sites and poses important problems to characterize sites without obvious visible architectural remains. Through a combination of remote sensing (satellite imagery, terrestrial and UAV-based photogrammetry) GIS analysis and field survey, two sites in the area were documented in detail with a cost-effective procedure that has allowed us to produce a more refined interpretation of them and their archaeological contexts. Considering the simplicity of the methods and the tools involved, we suggest that this methodology can inspire future work in this and similar regions.

通过Hualfín山谷（阿根廷卡塔马卡）进行3D映射和表面调查的文档和分析现场经验

摘要本文介绍了在Hualfin山谷（阿根廷卡塔马卡）开发的一种经验，旨在检验无创方法用于记录和分析不显眼自然部位的方法的实用性和适用性。在该地区，野外作业是建筑遗迹和考古资料的参考资料。但是，这会产生站点的部分文档，并且在表征站点而没有明显可见的体系结构残留物时会遇到重要问题。通过结合遥感（卫星图像，地面和基于无人机的摄影测量）GIS分析和野外勘测，该区域的两个地点均采用了具有成本效益的方法进行了详细记录，从而使我们能够对其进行更精细的解释及其考古背景。
