Atures Rock Art photography

This dataset combines photography of engraved rock art collected during the 2016 and 2017 field seasons in the Atures Rapids and Cerro Pintado. A full contextualisation of this data and accompanying discussion is published in Antiquity: The folders within this dataset correspond to the locations named in the Antiquity paper (Figure 1). Files with the prefix "DSC_" were shot with a Nikon D3100 DSLR in raw .NEF format and processed into a lossless image format (.png) in RawTherapee 4.2.447 with default settings. The original files are available upon request, but were prohibitively large to include in this archive. Files with the "WP_" prefix were taken as reference photos with a Nokia Lumia 920 smartphone. Those with "DJI" are aerial images taken with the standard camera on a DJI Phantom 2 Vision+ drone. Drone imagery in the three subfolders of the Picure folder are the source data used in Agisoft Photoscan Pro 1.3.1 to produce the following datasets included in this collection: "Picure Island Upper Petroglyph Panel West""Picure Island Upper Petroglyph Panel East""Picure Island Lower Petroglyph Panel" Photographic metadata (ISO, f-stop, focal length, exposure) including GPS coordinates in the cases of the smartphone and the drone, accompanies the files.

本数据集整合了2016与2017年野外考察季在阿图雷斯急流（Atures Rapids）和平塔多山（Cerro Pintado）采集的岩刻艺术摄影作品。本数据集的完整背景阐释与配套学术讨论已发表于《Antiquity》期刊。数据集内的文件夹与该期刊论文（图1）中提及的遗址位置一一对应。前缀为"DSC_"的文件均采用尼康D3100数码单反相机以.NEF原始格式拍摄，并通过RawTherapee 4.2.447以默认参数处理为无损图像格式（.PNG）。原始文件因体积过大无法纳入本归档包，但若有需求可另行申请获取。前缀为"WP_"的文件为采用诺基亚Lumia 920智能手机拍摄的参考照片。前缀为"DJI"的文件为采用DJI Phantom 2 Vision+无人机标配相机拍摄的航拍影像。Picure文件夹下的三个子文件夹所包含的无人机影像，是采用Agisoft Photoscan Pro 1.3.1制作本数据集收录的以下三组成果的源数据："Picure Island Upper Petroglyph Panel West"、"Picure Island Upper Petroglyph Panel East"以及"Picure Island Lower Petroglyph Panel"。所有文件均附带摄影元数据（感光度ISO、光圈f值、焦距、曝光参数），其中智能手机与无人机拍摄的文件还包含GPS坐标信息。
