Can Geotags Help Image Recognition? [PDF]

, 2009
In this paper, we propose to exploit geotags as additional information for visual recognition of consumer photos to improve its performance. Geotags, which represent places where the photos were taken, for photos can be obtained automatically by carrying a portable small GPS device with digital cameras.

Crowdsourced Data Reveal Shortcomings in Precipitation Phase Products for Rain and Snow Partitioning

Geophysical Research Letters, Volume 51, Issue 24, 28 December 2024.
Abstract Reanalysis products support our understanding of how the precipitation phase influences hydrology across scales. However, a lack of validation data hinders the evaluation of a reanalysis‐estimated precipitation phase. In this study, we used a novel dataset from the Mountain Rain or Snow (MRoS) citizen science project to compare 39,680 MRoS ...

Exposing illegal hunting and wildlife depletion in the world's largest tropical country through social media data

Conservation Biology, Volume 38, Issue 5, October 2024.
Abstract Globally, illegal sport hunting can threaten prey populations when unregulated. Due to its covert nature, illegal sport hunting poses challenges for data collection, hindering efforts to understand the full extent of its impacts. We gathered social media data to analyze patterns of illegal sport hunting and wildlife depletion across Brazil. We
