Introduction

As you have seen if you completed the previous chapter, ArcGIS Online is an amazing resource. It provides access to a wealth of data and tools that can greatly enhance the abilities of your GIS. But, can you add your own data and maps to your content, or are you limited to the content that is already there?

ArcGIS Online does allow you to publish your own content. This can take many forms, including:

• Data files:
  •  Shapefiles
  •  Text files (TXT and CSV)
  •  Spreadsheets
  •  PDF files
  •  Map packages
  •  Layer packages
  •  KML
  •  Styles
  •  And more…
• Web map and feature services:
  •  Publish directly through ArcGIS Online
  •  Connections to web maps from your own ArcGIS Server or Portal
• Web applications
• And more

For a full list of all the items you can add to your ArcGIS Online content, go to  https://doc.arcgis.com/en/arcgis-online/reference/supported-items.htm.
