Adopt a Pixel

Adopt a Pixel was removed from EarthExplorer, and is no longer available frome EROS. 2013 - 2019 Adopt a Pixel is a citizen science program that engages the public in collecting data, in this case landscape photographs, for scientific research. The science community has easy access to Landsat satellite data but has limited resources for acquiring ground reference photographs to verify land cover type. The goal of Adopt a Pixel is to acquire ground-based photographs to improve satellite data interpretation for operational and research science. Photographs from volunteers provide scientists with ground-based landscape data that would be too expensive or time consuming to acquire by other means. The digital photographs in this collection are provided by volunteers in the field. These images are geospatially referenced manually by the user, or automatically by the acquisition device. A simple, straightforward protocol for collection of scientifically useful ground reference data was developed and field tested in spring and summer 2013. The Landsat Science Team provided input on the protocol to ensure its scientific utility. The Adopt a Pixel collection continues to grow with the help from citizen scientists from across the globe. Volunteers can share their land cover photographs and participate in the program by visiting the USGS Earth Resources Observation and Science (EROS) Center Adopt a Pixel interface (adoptapixel.cr.usgs.gov). Images show the terrain from a single point facing North, South, East, West, Up, and Down to give a clear view of landscape features in all directions. Field observations include land cover classification and any notable comments about conditions, patterns, or changes.

‘Adopt a Pixel’项目已从地球探索者（EarthExplorer）平台下架，且无法再通过地球资源观测与科学（EROS）中心获取。该项目的时间跨度为2013年至2019年，‘Adopt a Pixel’是一项公民科学项目，旨在动员公众参与采集科研所需的数据——本项目中为景观照片。科学界可便捷获取陆地卫星（Landsat）卫星数据，但在获取用于验证土地覆盖类型的地面参考照片方面资源有限。‘Adopt a Pixel’项目的目标是采集地面实拍照片，以提升业务与科研场景下的卫星数据解译精度。志愿者提供的照片可为科研人员提供地面景观数据，这类数据若通过其他途径获取往往成本高昂或耗时极久。本数据集收录的数码照片均由野外志愿者提供。这些影像的地理空间坐标可由用户手动标注，亦可通过采集设备自动生成。项目组于2013年春夏研发了一套简洁易用的科学级地面参考数据采集规范，并完成了野外测试。陆地卫星（Landsat）科学团队为该规范提供了专业建议，以确保其科研实用性。‘Adopt a Pixel’数据集在全球各地公民科学家的参与下持续扩容。志愿者可访问美国地质调查局（USGS）地球资源观测与科学（EROS）中心的‘Adopt a Pixel’项目界面（adoptapixel.cr.usgs.gov），上传土地覆盖照片并参与本项目。所收录影像均从同一观测点拍摄，涵盖北、南、东、西、上、下六个方向的地表景观，可全方位清晰呈现区域地貌特征。野外观测内容包含土地覆盖分类结果，以及针对环境、格局或变化的相关备注信息。
