Fall of the Mayan culture - Climate changes fault? Our 3rd project in GIS Apps was to use what available information we have in an attempt to investigate whether climate change was a causal factor in the demise of the Mayan civilization. That being said, let's jump right in. The location of the Mayan culture is largely the Yucatan Peninsula. At it's peak, it was home to approximately 2 million people. The Mayans had quite a few advanced techniques in their repertoire which allowed them to flourish for some time. To begin the project, there's always the painstaking trials of finding data for use in GIS. Thanks to Phoebe, a fellow classmate offering a goldmine of a database, I began by finding the locations of the Mayan cities and cross-referencing their locations with the locations of the many Cenotes (sinkholes) and mines that dot the landscape as both have the potential to provide freshwater sources for local people. In the northern part of the peninsula, th
