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 …

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—to allow these two …

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 …
