Mapping Your Own Data 5:20
You can also upload your OWN data into ArcGIS Online. This may be my favorite capability of all, of ArcGIS Online. Let's begin by uploading a simple csv (comma separated value) file containing cities and states. Here is my csv file, of the Kansas City Royals radio stations that broadcast their games. Let's open up a map. I will drag the csv file to my ArcGIS Online session: I have addresses: city and state; add layer, and now it is geocoding the locations. This is the pattern of radio stations. Now I will add a circle on Kansas City, which is where the Royals play. I can see the pattern of stations clustered around Kansas City. The freehand area I can draw represents a sort of "listener area". I could do the same thing with other teams: St Louis Cardinals, Minnesota Twins. I can now change the symbols and start analyzing patterns. Recently we had a webinar on gapminder and also on worldmapper.org. Both of those wonderful sites contain Excel spreadsheets (csv's) of data. Well, now you know you can map those rich data sets in ArcGIS Online!
Here is a GPX file that I saved from my smartphone, in this case from the Motion X GPS iPhone app. Add layer from file: The file is on my own computer. Import layer. There it is! All mapped. Change the base map to an aerial image. I will now change the symbology to indicate elevation. I will change the lowest elevation class to yellow for visibility, and now I can see where I began hiking at this cul-de-sac, to the ridgetop, down this trail across these ravines to the ridge, back to the vehicle. I could have used Android's MyTracks - end goal: Generate a GPX and map it in ArcGIS Online for whatever fieldwork you have.
Think about YOUR students' data - of occurrence of litter, locations of historical buildings, water quality along a stream reach, and so on. It can all be mapped BUT you don't want to just map things because "you can" - you want to do it so that you can then analyze the spatial patterns.
