“…These were clipped into the interesting area, and then the ‘cost distance’ on the spatial analysis tool was utilized for evaluating the slope in terms of the cost raster, which is the main recognized factor in this study (Hayakawa et al, 2008). Finally, the optimal path was generated to the endpoints or moated sites by the ‘cost path’ tool and was then calculated as a polyline (Chandio et al, 2012; Lewis, 2017; Orengo & Livarda, 2016).…”

A large number of ancient remnants from the Angkor kingdom of the 15th–19th centuries are widely observable across present day north‐eastern Thailand and Cambodia. Archaeologically, these features represent the ancient communities and were possibly connected according to various socioeconomic reasons. In order to reconstruct the route of human mobility between the remains, the geographic information system (GIS)‐based least cost path (LCP) analysis was employed along the Angkor–Phimai route. By recognizing the geographic parameters, the mobility of 292 moated sites was tracked to eight mountain passes that traverse the barrier of the Dângrêk Mountain Range. The LCP‐derived routes revealed that the Ta Muen pass was the most suitable (shortest source‐to‐site distance) route for almost all moated sites. When compared with a previous interpretation of the Angkorian Royal Road route, our LCP route conforms reasonably well when overlaid with this possible Royal Road. The locations of ancient activities were also in the vicinity of the dense LCP route, and most monuments were located within a 1.5 km buffer line. This underlines that the LCP track obtained in this study is reasonable with a high reliability and is beneficial for guiding further studies to find out more about the ancient remains or archaeological evidence in this area.

This research aims to apply�remote sensing and luminescence dating�to study archaeological sites in Buriram Province, Northeastern Thailand. There are three main objectives including 1) to model the ancient path from the mountain passes along the D?ngr?k mountain to ancient community on Angkor Highland or Northeast Thailand, 2) to directly date slag from the ancient iron smelting site at Ban Sai To 7, and 3) determine the terminal age of Ban Sai To 7 site using technical ceramics. Firstly, the results of the GIS-based least cost path (LCP) route, using topographic factors, show that Ta Muen, Sai Ta Ku, and Krang are the most suitable for transportation between the Khorat plateau and present Cambodia.�These results are consistent with archaeological evidence i.e., Dharmasalas. Most Khmer monuments are located in the vicinity of LCP routes.�Moreover, the LCP route of Ta Muen is significant with the location of the ancient industrial zone in Ban Kruat District. However, most ancient smelting sites were in the Iron Age, although they were assumed to be active during the Khmer period when compared with the relative findings. The major challenge of archaeometallurgy is the limitation of suitable sample for the scientific dating method. Therefore, the�second is to investigate the absolute date of slag in the ancient iron-smelting site at Ban Sai Tho 7 by luminescence dating. The result slag shows the luminescence signal. Therefore, luminescence dating is an effective method to directly date slag. Moreover, the results show that the terminal activity of this site is 140 years ago. This result is in good agreement with the terminal period of ancient iron smelting in Cambodia. Finally, the dates of technical ceramics i.e., furnace and tuyere fragments in the slag heap at Ban Sai Tho 7, show that there were at least two different periods of furnace�construction�including�360-370�years and 1000-1110 years ago. It is indicated that there are many phrases of smelting in one heap. When comparing the ages between slags and technical ceramics, the results of these two materials are in good agreement. Moreover, this finding shows that the large size of the ancient iron-smelting site at Ban Sai Tho 7 came from a long operational lifespan rather than a large operation in a short period.�The route of ancient transportation is significant with the location of ancient industrial zone especially ancient iron-smelting sites that had been since the Iron Age, the Khmer Period and the post-Khmer period.
