Adding value to GIS – some spatial-analytical techniques and their applications

TL;DRAbstract

7-11 February 2005 This paper explores some recent developments in spatial analysis which maybe of use to archaeologists as add-ons to GIS. It starts by describing different types of spatial data, and the types and characteristics of the spatial processes that may generate them. The focus is then on two types of data: point-pattern and spatially continuous (geostatistical) data. Techniques of point-pattern analysis were imported into archaeology from ecology, and brought with them three major issues: the question of scale, the problem of edge effects and the question of the quality and consistency of archaeological data. Recent statistical developments have overcome the first two; the last is always with us. A case study uses the ADS module of the statistical package ADE-4 to show how modern techniques can shed light on patterns of the distributions of artefacts of different types on an archaeological site, through the use of diagnostic statistics and graphical displays. The study of s
