Need an easy way to make a point data file within ArcGIS Online, doing data entry within the map? This five-minute video (silent but annotated) shows how to turn a simple two-line text file into a way to add data points with attributes to your map.
Generally, mapping and classifying a set of points with attributes is easier to do by generating your complete data table as a spreadsheet first, and then mapping the completed spreadsheet, but sometimes you need a different workflow. (If you are reconstructing data from a field trip or outing after the fact, this is one way to do it.) The movie shows how you can start with a small data set, and expand the number of records over time, and classify them.
