The data shared below include the complete set of vector layers in wither shapefile or Esri geodatabase format and the 50 meter DEM of middle earth as four quadrants (geo tiff format). The maps are treated as if they are of real landscapes, drawn according to the rules of a real atlas. Students then develop a story map to share their work at the end of the semester. The Atlas of Middle-earth provides many detailed maps of the lands described in Tolkiens books. The final cost layer is then used in a least cost path analysis to map a better route for Frodo. Cost-to-travel layers include the slope and ruggedness of the terrain, ease of travel across different land cover types, and width of rivers based on derived stream order. Example threat layers included proximity to orcs, danger levels within different realms, and the likelihood of being seen by Sauron. Each team sets out to develop a minimum of three threat layers and three cost-of-travel layers that are combined using a weighted sum analysis into the final cost layer. This GIS & Middle Earth course is designed to allow teams of students to integrate their GIS skill with their interest in Tolkien’s Middle Earth to develop the cost layers needed to run a least cost path analysis from the Shire to Mount Doom. These data formed the basis for an advanced GIS course where students expanded their GIS skills through a creative mapping and analysis set in Middle Earth. With the right spatial data layers and utilizing the power of a geographic information system, a least cost path analysis could reveal whether there was a better route that Frodo could have taken from the Shire to Mount Doom to destroy the ring of power.Īfter several years of development, the Center for Geospatial Analysis at William & Mary, has developed an extensive list of GIS layers of Middle Earth, including a 50 meter elevation model, roads, rivers, realms and many others. Did Frodo take the best path to destroy the One Ring?
