Google Earth and high-resolution satellite imagery provide a means of carrying out remote-sensing survey of Hafit tombs able to cover large areas in short periods of time. While the potential of such research has already been demonstrated in the Wādī Andam area, the accuracy and precision of the methodology are not yet clear. A ground survey carried out by a Sultan Qaboos University (SQU) team in western Ja'alan provides an excellent control to assess the efficacy of the method. The study area was surveyed using Google Earth, and the two datasets were compared. Hafit tombs were identified to a high level of accuracy, but approximately 50% of the structures were not visible, with badly preserved tombs more likely to be missed than those in good condition. Remote sensing can be used in the preliminary stages of survey or more generally to discover and analyse broad patterns of Hafit tomb distribution. Comparisons of the distribution of Hafit tombs in western Ja'alan and Wādī Andam reveal clear similarities: the structures occupy elevated positions adjacent to sizeable wadi channels. The density of tombs is much greater in the western Ja'alan study area, which may suggest that Wādī Batha supported a larger Hafit population than Wādī Andam.

阿曼 ash-Sharqiyah 的 Hafit 墓葬：评估 Google Earth 遥感勘测的准确性和精度并分析它们在景观中的分布

谷歌地球和高分辨率卫星图像提供了一种对哈菲特墓葬进行遥感调查的手段，能够在短时间内覆盖大片区域。虽然这种研究的潜力已经在 Wādī Andam 地区得到证明，但该方法的准确性和精确度尚不清楚。由位于 Ja'alan 西部的 Sultan Qaboos 大学 (SQU) 团队进行的地面调查为评估该方法的有效性提供了极好的控制。使用谷歌地球对研究区域进行了调查，并对两个数据集进行了比较。Hafit 墓葬的鉴定准确度很高，但大约 50% 的结构不可见，保存完好的墓葬比完好无损的墓葬更容易被遗漏。遥感可用于调查的初步阶段或更广泛地用于发现和分析 Hafit 墓葬分布的广泛模式。对 Ja'alan 西部和 Wādī Andam 的 Hafit 墓葬分布的比较揭示了明显的相似之处：这些结构占据了与大型河道相邻的较高位置。Ja'alan 研究区西部的墓葬密度要大得多，这可能表明 Wādī Batha 比 Wādī Andam 支持的 Hafit 人口更多。
