Description of the activity/assignmentThis GIS lab exercise investigates the use of the ArcGIS Spatial Analyst extension tools to construct a viewshed of the Chaco Canyon area in New Mexico. Students will build a simple point location map of several ruins in Chaco Canyon. Assuming that some of the cliff-top ruins were used as lookout towers, viewshed analysis is applied to see if this was possible.
Determining whether students have met the goalsStudents are assessed through (1) examaination of the resulting viewshed maps and (2) cartographic presentation of the results.
