The ETM and ALCE testing: Summer internship in Clark labs

Wenle Jiang

This paper is a description of my internship with Clark Labs in the summer of 2017. I worked as research assistant responsible for testing the Earth Trends Modeler and the American Land Change Explorer. Earth Trends Modeler is a revolutionary earth observation tool that allows for the modeling and analysis of earth trends and ecosystem dynamics. The American Land Change Explorer (ALCE) is a free web application designed to illustrate the potential of predictive land change modeling using a subscription-based service called the American Land Change Modeler (ALCM). Working in Clark Labs allows me to learn from intelligent and successful GIS professionals and learn about how GIS software products are developed. I highly recommend this internship with Clark Labs to other GISDE students who are interested in remote sensing and programming.
