TotalStation data from Experiment 1a in the manuscript "The Importance of Search Strategy for Finding Targets in Open Terrain".<br>Abstract:<br> A number of real world search tasks (i.e., police search, IED detection,) require searchers to search exhaustively across open ground. In the present study, we simulated this problem by asking individuals (Experiments 1a and 1b) and dyads (Experiment 2) to search for coin targets pseudo-randomly located in a bounded area of open grassland terrain. In Experiment 1a, accuracy, search time and the route used to search an area were measured. Participants tended to use an ‘S’ shaped pattern with a common width of search lane. Increased accuracy was associated with slower, but also variable, search speed, though only when participants moved along the length (as opposed to across the width) of the search area. Experiment 1b ,varied the number of targets available within the bounded search area and in doing so varied target prevalence and density. The results confirmed that the route taken in Experiment 1a generalizes across variations in target prevalence/density. In Experiment 2, accuracy, search time, and the search strategy used by dyads was measured. While dyads were more accurate than individuals, dyads that opted to conduct two independent searches were more accurate than those who opted to split the search space. The implications of these results for individuals and pairs when searching for targets in open space are discussed.本数据集为论文《开放地形中目标搜寻策略的重要性》（The Importance of Search Strategy for Finding Targets in Open Terrain）的实验1a的全站仪(TotalStation)采集数据。 摘要： 诸多现实世界的搜寻任务（如警务搜查、简易爆炸装置（Improvised Explosive Device, IED）排查）均要求搜寻人员对开阔地面开展全面搜寻。本研究通过招募单人参与实验（含实验1a与1b）、双人小组参与实验2，让其搜寻伪随机分布于一片限定开阔草地范围内的硬币目标，以此模拟该类搜寻问题。在实验1a中，本研究记录了搜寻准确率、搜寻时长与区域搜寻路径三类指标。被试通常会采用宽度统一的“S”形搜寻路径模式。仅当被试沿搜寻区域的纵向（而非横向）行进时，更高的搜寻准确率会与更慢且波动更大的搜寻速度相关联。实验1b通过调整限定搜寻区域内的目标数量，以此改变目标的出现率与分布密度。实验结果证实，实验1a中采用的搜寻路径模式可推广至不同目标出现率与密度的场景。在实验2中，本研究记录了双人小组的搜寻准确率、搜寻时长与搜寻策略三类指标。尽管双人小组的搜寻准确率高于单人，但相较于选择拆分搜寻区域的小组，选择各自独立开展搜寻的双人小组准确率更高。本研究最后讨论了上述结果对单人与双人在开阔空间开展目标搜寻的实践启示。
