title: Wadi Hasa Sample Dataset — GRASS GIS Location

description: OverviewThe Wadi Hasa Sample Dataset — GRASS GIS Location packages a complete, ready-to-use spatial workspace for archaeological geomorphometry and landscape analysis in the Wadi Hasa region (central Jordan). It accompanies a teaching chapter and supports reproducible exercises in terrain modeling, hydrology, viewshed/visibility, movement and least-cost analysis, site catchments/territories, and predictive modeling (both deductive and inductive/ML).

The archive is a standard GRASS GIS Location with multiple Mapsets and an included Workspace.gxw project file so users can open, inspect, and run workflows immediately. The dataset targets graduate and advanced undergraduate instruction in Archaeological GIS and is suitable for method demonstrations and small research replications.

Contents (summary)





Data model: GRASS Location with SQLite attribute storage; rasters/vectors organized by thematic Mapsets.




Layer inventory: 230 raster maps and 34 vector maps spanning 10 m, ~30 m, ~208–232 m, and 1 km resolutions.




Mapsets (thematic subprojects):Terrain_Analysis, Visibility_Analysis, Least_Cost_Analysis, Territory_Modeling, Site_Buffer_Analysis,Boolean_Predictive_Modeling, Machine_Learning_Predictive_Modeling,Landsat_Imagery, Sentinel2_Imagery,ISRIC_soilgrid, Trace21k_Paleoclimate_Downscale_Example,Landscape_Evolution_Modeling, PERMANENT




Codebooks & data dictionaries (CSV at archive root): Landform_Codes.csv, Site_Type_Codes.csv, Temporal_periods.csv.




Representative content:• Terrain & hydrology: SRTM-derived DEM and derivatives (slope/aspect/curvature, geomorphons/landforms, flow accumulation, basins), insolation/topo-climatology.• Archaeological vectors: Wadi Hasa Survey (WHS) and Wadi Hasa North Bank Survey (WHNBS) points; Nabataean and Roman towers; derived path/stream/catchment features.• Movement: isotropic/anisotropic cost surfaces, time-to-travel rasters, and least-cost paths.• Visibility: single and cumulative viewsheds for selected features.• Predictive modeling: Boolean/deductive surfaces and ML-based workflows with training/test partitions.• Environmental context: ISRIC SoilGrids (soil classes and properties), CHELSA TraCE21k paleoclimate examples (MAT/AP time slices), Landsat and Sentinel-2 products (e.g., NIR/RED/NDVI; RGB composites).



Spatial reference





CRS: WGS 84 / UTM Zone 36N (EPSG:32636); horizontal/vertical units in meters.




Default computational region: set within the Location; reproducibility commands are provided in the included README.txt.



Methods (brief)Workflows rely on core GRASS GIS 8.x modules for terrain analysis (r.slope.aspect, r.param.scale, r.geomorphon, r.watershed, r.sun), cost/paths (r.walk, r.cost, r.path, r.drain), visibility (r.viewshed), and attribute/overlay tools (v.what.rast, v.rast.stats, v.db.*). Example ML paths reference GRASS’s r.ml.* interface; soil and paleoclimate products are resampled to harmonize with 30 m terrain derivatives for teaching purposes (with scale caveats noted in the README).

Forthcoming book context: This dataset accompanies the chapter “Geomorphometry for archaeology,” prepared for the second edition of Geomorphometry: Concepts, Software, Applications (eds. H. I. Reuter, C. H. Grohmann, V. Lecours; Elsevier; expected 2026). Publisher listing (metadata subject to change): https://www.google.com/books/edition/Geomorphometry/EYoI0QEACAAJ?hl=en



Intended useDesigned for classroom labs, methods demonstrations, and reproducible examples in archaeological landscape analysis. Users can adopt the Mapsets piecemeal, or open the provided GRASS workspace to reproduce figures/analyses from the teaching chapter.
