If you are new to GIS, the easiest place to start is with ArcGIS Online (AGOL). You can log in and use the mapping app from any device, and membership is free for UC Merced students, faculty, and staff. An organizational account through the GIS Center opens access to expanded analytics and Esri training and tutorials, as well as the option to download Esri's desktop software, ArcGIS Pro, for free. See the Training Tab above for AGOL tutorials.
