An Iterative 3d Gis Analysis Of The Role Of Visibility In Ancient Maya Landscapes: A Case Study From Copan, Honduras, Heather Richards-Rissetto Mar 2017

An Iterative 3d Gis Analysis Of The Role Of Visibility In Ancient Maya Landscapes: A Case Study From Copan, Honduras, Heather Richards-Rissetto

Anthropology Faculty Publications

For several decades, Geographic Information Systems (GISs) have held center stage in archaeological studies of ancient landscapes. Recently, three-dimensional (3D) technologies such as airborne LiDAR and aerial photogrammetry are allowing us to acquire inordinate amounts of georeferenced 3D data to locate, map, and visualize archaeological sites within their surrounding landscapes. GIS offers locational precision, data overlay, and complex spatial analysis. Three-dimensionality adds a ground-based perspective lacking in two-dimensional GIS maps to provide archaeologists a sense of mass and space more closely attuned with human perception. This article uses comparative and iterative approaches ‘tacking back and forth’ between GIS and 3D ...

Archaeological projects increasingly collect airborne LiDAR data to use as a remote sensing tool for survey and analysis. Publication possibilities for LiDAR datasets, however, are limited due to the large size and often proprietary nature of the data. Fortunately, web-based, geographic information systems (WebGIS) that can securely manage temporal and spatial data hold great promise as virtual research environments for working with and publishing LiDAR data. To test this and to obtain new data for archaeological research, in 2013, the MayaArch3D Project (www.mayaarch3d.org) collected LiDAR data for the archaeological site of Copan, Honduras. Results include: 1) more accurate ...


Movement As A Means Of Social (Re)Production: Using Gis To Measure Social Integration Across Urban Landscapes, Heather Richards-Rissetto, Kristin Landau Jan 2014

Movement As A Means Of Social (Re)Production: Using Gis To Measure Social Integration Across Urban Landscapes, Heather Richards-Rissetto, Kristin Landau

Anthropology Faculty Publications

This paper contributes to the archaeological study of movement in urban environments where built forms and natural features worked together to play a key role in structuring human mobility.We propose an analytical method using least cost analysis in a Geographic Information System (GIS) to empirically measure social integration. The method defines mobility as the potential for pedestrian movement, and identifies locations where people were most likely to walk to or through in a landscape. The calculated mobility data are then employed to identify with whom people were most likely to interact and the degree to which they were socially ...

There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models from a pedestrian perspective. Meanwhile, 3D models and virtual environments visualize data in 3D space, but analytical tools are simple rotation or lighting effects. The MayaArch3D Project is developing a 3D WebGIS—called QueryArch3D ...


From Mounds To Maps To Models: Visualizing Ancient Architecture Across Landscapes, Heather Richards-Rissetto Jan 2013

From Mounds To Maps To Models: Visualizing Ancient Architecture Across Landscapes, Heather Richards-Rissetto

Anthropology Faculty Publications

Since the onset of settlement pattern studies in the 1950s, landscape mapping projects have become an archaeological mainstay. Remote sensing technologies such as lidar, photogrammetry, and SAR (Synthetic Aperture Radar) steadily reveal new archaeological sites. For landscape archaeology, the detection and mapping of small architectural complexes and households offers important data to contextualize larger (often already known) sites and perform regional analyses. However, because the majority of sites remain unexcavated, analysis is limited, and yet Geographic Information Systems (GIS) and 3D Visualization are expanding the possible uses for older and newly-acquired data on unexcavated mounds. This paper describes a GIS ...
