Despite being widely accepted as a hindrance, few studies have explicitly demonstrated the impact vegetation can have on remote lithological mapping. Accordingly, this study comprehensively elucidates the impact of vegetation on the lithological mapping capability of airborne multispectral data in the Troodos region, Cyprus. Synthetic spectral mixtures were first used to quantify the potential impact vegetation cover might have on spectral recognition and remote mapping of different rock types. The modeled effects of green grass were apparent in the spectra of low albedo lithologies for 30%\u201340% fractional cover, compared to just 20% for dry grass cover. Lichen was found to obscure the spectra for 30%\u201350% cover, depending on the spectral contrast between bare rock and lichen cover. The subsequent impact of vegetation on the remote mapping capability is elucidated by considering the outcomes of three airborne multispectral lithological classifications alongside the spectral mixing analysis and field observations. Vegetation abundance was found to be the primary control on the inability to classify large proportions of pixels in the imagery. Matched Filtering outperformed direct spectral matching algorithms owing to its ability to partially unmix pixel spectra with vegetation abundance above the modeled limits. This study highlights that despite the limited spectral sampling and resolution of the sensor and dense, ubiquitous vegetation cover, useful lithological information can be extracted using an appropriate algorithm. Furthermore, the findings of this case study provide a useful insight to the potential capabilities and challenges faced when utilizing comparable sensors (e.g., Landsat 8, Sentinel-2, WorldView-3) to map similar types of terrain.<\/jats:p>","DOI":"10.3390\/rs61110860","type":"journal-article","created":{"date-parts":[[2014,11,7]],"date-time":"2014-11-07T08:18:31Z","timestamp":1415348311000},"page":"10860-10887","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":36,"title":["The Impact of Vegetation on Lithological Mapping Using Airborne Multispectral Data: A Case Study for the North Troodos Region, Cyprus"],"prefix":"10.3390","volume":"6","author":[{"given":"Stephen","family":"Grebby","sequence":"first","affiliation":[{"name":"British Geological Survey, Keyworth, Nottingham NG12 5GG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dickson","family":"Cunningham","sequence":"additional","affiliation":[{"name":"Department of Environmental Earth Science, Eastern Connecticut State University, Willimantic,  CT 06226, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9116-8081","authenticated-orcid":false,"given":"Kevin","family":"Tansey","sequence":"additional","affiliation":[{"name":"Department of Geography, University of Leicester, University Road, Leicester LE1 7RH, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan","family":"Naden","sequence":"additional","affiliation":[{"name":"British Geological Survey, Keyworth, Nottingham NG12 5GG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2014,11,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"501","DOI":"10.1190\/1.1440721","article-title":"Spectral signatures of particulate minerals in visible and near infrared","volume":"42","author":"Hunt","year":"1977","journal-title":"Geophysics"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"587","DOI":"10.1144\/gsjgs.144.4.0587","article-title":"Improved discrimination of rock units using Landsat Thematic Mapper imagery of the Oman ophiolite","volume":"144","author":"Rothery","year":"1987","journal-title":"J.
