ABSTRACT T’hó –a Mayan city cited in historical documents – has been discovered and is now a topic in current archaeological discussions and research topics due to a joint UNAM and UADY research project. This project encompassed several steps, including the recording of material recovered from the city’s subsoil while monitoring urban infrastructure programs, as well as the study of historical documents and maps and finally verifying hypothesis by using georadar. After surveying almost 17 km of paved streets in downtown Merida, we realized that it was possible to recognize three main deposit layers underlying the area. The uppermost layer showed modern fillings and urban infrastructure, the intermediate layer had pre-Hispanic cultural remains, and the deepest one included limestone bedrock. This study constitutes the first attempt to create a map of the remains underlying downtown Merida City in order to know and preserve its archaeological patrimony.

搜寻Georadar古代T'hó，这是现代梅里达（Merida）尤卡坦半岛下方的玛雅城市

已被历史文献中引用的玛雅城市-抽象的T'hó被发现，由于UNAM和UADY的联合研究项目，现在已成为当前考古学讨论和研究主题的主题。该项目包括几个步骤，包括在监视城市基础设施计划的同时记录从城市地下土壤中回收的材料，以及研究历史文档和地图，最后使用Georadar验证假设。在调查了梅里达市中心近17公里的铺装街道后，我们意识到可以识别该地区下面的三个主要沉积层。最上层显示现代填充物和城市基础设施，中层显示西班牙裔前的文化遗迹，最深层包括石灰岩基岩。
