摘要

自从无人机进入大众市场供私人用户使用以来，无人机飞行员开始在各种无人机平台上分享地理标记的航空照片和视频。本研究比较了三个众包平台(Dronestagram、Travelwithdrone和Flickr)基于地理参考的无人机图像和视频的时空贡献模式。该比较涉及空间精度、地理覆盖、贡献不平等、不同贡献特征的幂律近似，以及识别与图像和视频贡献数相关的人为和自然特征、社会经济因素和土地利用类别的负二项多水平回归模型。这项研究为全球范围内大量基于无人机的图像和视频贡献提供了新的见解，有助于确定哪个无人机平台最适合为特定位置找到无人机媒体，并讨论了一些可能从众包无人机图像和视频中受益的潜在应用。

Comparison of spatiotemporal contribution patterns among three crowd-sourcing drone platforms

ABSTRACT Since the introduction of drones to the mass market for private users, drone pilots have started to share geo-tagged aerial photos and videos on a variety of drone platforms. This study compares the spatio-temporal contribution patterns of georeferenced drone-based images and videos between three crowd-sourcing platforms, namely Dronestagram, Travelwithdrone, and Flickr. The comparison addresses aspects of spatial accuracy, geographic coverage, contribution inequality, power-law approximations of different contribution characteristics, and negative binomial multilevel regression models that identify man-made and natural features, socio-economic factors, and land use categories that are associated with image and video contribution numbers. This study provides new insight into the abundance of drone-based image and video contributions around the globe, helps to determine which drone platform is best suited to find drone media for a specific location, and discusses a few potential applications that could benefit from crowd-sourced drone imagery and videos.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
