For animals with spatially complex behaviours at relatively small scales, the resolution of a global positioning system (GPS) receiver location is often below the resolution needed to correctly map animals’ spatial behaviour. Natural conditions such as canopy cover, canyons or clouds can further degrade GPS receiver reception. Here we present a detailed, high-resolution map of a 4.6 ha Neotropical river island and a 8.3 ha mainland plot with the location of every tree >5 cm DBH and all structures on the forest floor, which are relevant to our study species, the territorial frog Allobates femoralis (Dendrobatidae). The map was derived using distance- and compass-based survey techniques, rooted on dGPS reference points, and incorporates altitudinal information based on a LiDAR survey of the area.

对于在相对较小的尺度上具有空间复杂行为的动物，全球定位系统 (GPS) 接收器位置的分辨率通常低于正确映射动物空间行为所需的分辨率。树冠覆盖、峡谷或云层等自然条件会进一步降低 GPS 接收器的接收性能。在这里，我们展示了一个 4.6 公顷的新热带河岛和一个 8.3 公顷的大陆地块的详细高分辨率地图，其中每棵树的位置 > 5 厘米 DBH 和森林地面上的所有结构，这与我们的研究物种有关，领地蛙Allobates femoralis (Dendrobatidae)。该地图是使用基于距离和罗盘的调查技术得出的，基于 dGPS 参考点，并结合了基于该地区的 LiDAR 调查的高度信息。
