Research is focused on the identification of Neolithic felsite stone tool workshops in the North Mavine region of the Shetland Islands in Northern Scotland. Sample data from known workshops surveyed using differential GPS are used alongside known non-sites to train a linear discriminant analysis (LDA) classifier based on a combination of datasets including Worldview-2 bands, band difference ratios (BDR) and topographical derivatives. Principal components analysis is further used to test and reduce dimensionality caused by redundant datasets. Probability models were generated by LDA using principal components and tested with sites identified through geological field survey. Testing shows the prospective ability of this technique and significance between 0.05 and 0.01, and gain statistics between 0.90 and 0.94, higher than those obtained using maximum likelihood and random forest classifiers. Results suggest that this approach is best suited to relatively homogenous site types, and performs better with correlated data sources. Finally, by combining posterior probability models and least-cost analysis, a survey least-cost efficacy model is generated showing the utility of such approaches to archaeological field survey.<\/jats:p>","DOI":"10.3390\/rs8060529","type":"journal-article","created":{"date-parts":[[2016,6,23]],"date-time":"2016-06-23T18:29:50Z","timestamp":1466706590000},"page":"529","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Posterior Probability Modeling and Image Classification for Archaeological Site Prospection: Building a Survey Efficacy Model for Identifying Neolithic Felsite Workshops in the Shetland Islands"],"prefix":"10.3390","volume":"8","author":[{"given":"William","family":"Megarry","sequence":"first","affiliation":[{"name":"Cultural Site Research and Management, 2113 St Paul, Baltimore, MD 21218, USA"},{"name":"School of Archaeology, University College Dublin, Belfield, Dublin, Ireland"},{"name":"Department of Applied Mathematics and Statistics, Johns Hopkins University, 3400 North Charles Street, Baltimore, MD 21218, USA"}]},{"given":"Gabriel","family":"Cooney","sequence":"additional","affiliation":[{"name":"School of Archaeology, University College Dublin, Belfield, Dublin, Ireland"}]},{"given":"Douglas","family":"Comer","sequence":"additional","affiliation":[{"name":"Cultural Site Research and Management, 2113 St Paul, Baltimore, MD 21218, USA"}]},{"given":"Carey","family":"Priebe","sequence":"additional","affiliation":[{"name":"Department of Applied Mathematics and Statistics, Johns Hopkins University, 3400 North Charles Street, Baltimore, MD 21218, USA"}]}],"member":"1968","published-online":{"date-parts":[[2016,6,22]]},"reference":[{"key":"ref_1","unstructured":"Mahler, D.L.D.
