You don't always need a complex GIS application in order to explore spatial relationships in a project, and sometimes you just want a custom map, quickly, to illustrate a presentation or visualize locations in a dataset. Fortunately, creating maps is easier than ever with web-based mapping platforms such as CARTO, Google Earth, and ArcGIS Online. In this workshop we'll look at uses of web-based mapping and spend hands-on time with tools to create maps online. Participants are encouraged to bring data they might be interested in mapping; no prior experience with mapping is expected.
