Dataset on georeferenced and tagged photographs for ecosystem services assessment, Ebro Delta, N-E Spain

A georeferenced and tagged dataset of photographs is presented. Over 2,000 photographs from the Ebro Delta Natural Park, N-E Spain, have been treated. Raw data come from Wikiloc, a Volunteered Geographic Information source, and have been cleansed and systematized. The photographs have been classified according to their image content. An automatic first analysis was performed using 8-bit software. For uncertain tags, a second supervised analysis was performed. Classification into eight types and thirty-seven subtypes was conducted by considering landscape and social reactions. Data have been treated with the ArcGis 10.2. Geographic Information System. This dataset is useful for understanding ecosystem services by means of users’ photographs.本数据集为一组经过地理配准与标签标注的摄影图像数据集。共收录来自西班牙东北部埃布罗河三角洲自然公园的2000余张摄影图像并完成标准化处理。原始数据源自志愿地理信息（Volunteered Geographic Information）平台Wikiloc，已完成数据清洗与系统化规整。已依据图像内容对所有摄影图像进行分类：首先采用8位图像处理软件完成自动初分类分析；针对标签存疑的样本，开展了第二次有监督分析。本次分类结合景观特征与社会反馈维度，将图像划分为8大类与37个子类。所有数据均通过ArcGIS 10.2地理信息系统完成处理。本数据集可用于通过用户上传的摄影图像解析生态系统服务功能。
