Many large cities in the South American Andes are located above 2500m and rely almost entirely on high-altitude water stocks. This research focuses on rock glaciers in the Bolivian Andes. Remote sensing data sources including historic air photos, fine spatial resolution satellite data (IKONOS 5 m resolution), global-extent Digital Elevation Models, and Google Earth, are used to establish a detailed spatial understanding of rock glacier physical characteristics.enREMOTE SENSINGBOLIVIATROPICAL ANDEAN GLACIERSGLACIER RECESSIONWATER SECURITYDATA COLLECTINGNATURAL RESOURCE SURVEYSPHOTOGEOLOGYAERIAL SURVEYSJournal Article
