Automated relief representation for visualisation of archaeological monuments and other anthropogenic forms

摘要: Abstract Both within the Royal Commission on Ancient and Historic Monuments for Scotland (RCAHMS) Ordnance Survey (OS) there are specific requirements to record Historical (such as ramparts mounds) various anthropogenic forms road rail embankments). The traditional method of relief representation archaeology employs ‘hachures’ (a hachure being a hand drawn line along steepest gradient slope in direction that slope). Hachuring has proved be highly effective form representation—superior circumstances, alternatives such contours shading. However, it is acknowledged extremely time consuming context current GIS solutions. Developments automated cartography digital databases UK's Digital National Framework, have led requirement an algorithm automatically generates hachures with minimum human input, simplest database requirements. This paper reports automatic required order visualise archaeological monuments GIS. program takes input isolines defining top bottom populates region whilst addressing comprehensive set design issues. Results implementation presented evaluated against results.
