How To: Attach a file to a feature point in a shapefile in ArcGIS Online

Summary

The instructions provided describe how to attach files, such as images and PDFs, via a URL link to feature points in a shapefile in ArcGIS Online (www.arcgis.com).

ArcGIS Online is unable to store the physical file in the map pop-up. However, the file is referenced by using a static URL that has been published and shared publicly. The file may be uploaded to ArcGIS Online or an external site with a static URL, such as Dropbox or Google Docs.

Procedure

Steps in ArcMap

1. Add a new text field to the attribute table of the features in the shapefile by following the instructions in ArcGIS Resources: Adding fields.

To store the URL in the attribute table, add the new text field with the following properties.
