Observations of lines-of-sight in Guadeloupe. This archive includes the digital information collected in the framework of the Guadeloupe visibility survey (GUA-V) performed by Tom Brughmans from 5 to 14 March 2015 in Guadeloupe. The archive contains spreadsheets with all line-of-sight observations made, the moment they were made and the locations they were made from (in the folder GUA-V_survey-observations), and CSV files with spatial information of the point locations and lines-of-sight in WKT format that can be imported into GIS software (in the folder GUA-V_GIS). The results were published in: Brughmans, T. et al., Exploring Transformations in Caribbean Indigenous Social Networks through Visibility Studies: the Case of Late Pre-Colonial Landscapes in East-Guadeloupe (French West Indies) Journal of Archaeological Method and Theory 25, (June 2018). This research was carried out as part of Humanities in European Research Area (HERA), grant no 1133.
