Most demographic, economic, health, and education maps start with tabular data of some kind. This article will describe several ways you can turn a flat file of raw data into a feature layer. Feature layers allow you to do spatial analysis and create web maps that can be shared in apps and story maps.
Add a Spreadsheet with Location Data, Geocode, and Create Points
Often, data analysts and GIS specialists need to turn a spreadsheet on a local computer into a feature layer. In this example, I have a local spreadsheet containing information about Medicare spending per patient for various hospitals. The fields that contain location data for each hospital are called Address, City, State, and Zip_Code.
I am signed in to my ArcGIS Online organization account and have a User Type that allows me to publish hosted feature layers (Creator, GIS Professional, or Insights Analyst User Types). I have some analysis credits as these methods will consume credits, based on how many records are contained in my data.
