Usually they are obtained via either satellite imaging or ground based manual measurements; both are bespoke and therefore costly and have problems associated with scale and quality. An increase in the use of camera networks for monitoring infrastructure offers a means of obtaining images for use in phenological studies, where the only necessary outlay would be for data transfer, storage, processing and display. Here a pilot study is described that uses image data from a traffic monitoring network to demonstrate that it is possible to obtain usable information from the data captured. There are several challenges in using this network of cameras for automatic extraction of phenological metrics, not least, the low quality of the images and frequent camera motion. Although questions remain to be answered concerning the optimal employment of these cameras, this work illustrates that, in principle, image data from camera networks such as these could be used as a means of tracking environmental change in a low cost, highly automated and scalable manner that would require little human involvement.<\/jats:p>","DOI":"10.3390\/rs5052200","type":"journal-article","created":{"date-parts":[[2013,5,10]],"date-time":"2013-05-10T14:17:28Z","timestamp":1368195448000},"page":"2200-2218","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Exploring the Potential for Automatic Extraction of Vegetation Phenological Metrics from Traffic Webcams"],"prefix":"10.3390","volume":"5","author":[{"given":"David","family":"Morris","sequence":"first","affiliation":[{"name":"Electrical Systems and Optics Division, Faculty of Engineering, University of Nottingham, University Park, Nottingham NG7 2RD, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Doreen","family":"Boyd","sequence":"additional","affiliation":[{"name":"School of Geography, University of Nottingham, University Park, Nottingham NG7 2RD, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John","family":"Crowe","sequence":"additional","affiliation":[{"name":"Electrical Systems and Optics Division, Faculty of Engineering, University of Nottingham, University Park, Nottingham NG7 2RD, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caroline","family":"Johnson","sequence":"additional","affiliation":[{"name":"Electrical Systems and Optics Division, Faculty of Engineering, University of Nottingham, University Park, Nottingham NG7 2RD, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karon","family":"Smith","sequence":"additional","affiliation":[{"name":"School of Geography, University of Nottingham, University Park, Nottingham NG7 2RD, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2013,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"566","DOI":"10.1111\/j.1365-2486.2011.02562.x","article-title":"Terrestrial biosphere models need better representation of vegetation phenology: Results from the North American Carbon Program Site Synthesis","volume":"18","author":"Richardson","year":"2012","journal-title":"Glob.
