SharePoint lists can contain columns that store the geographic location of each item as latitude and longitude. Spatially enabling such lists so that they can be displayed on the Map Web Part requires adding and configuring an ArcGIS Location Field.
The current version of the ArcGIS Map Web Part only supports adding a location field to lists with World Geodetic System 1984 (WGS84) geographic coordinates. WGS84 is the most widely used geocentric datum and geographic coordinate system today. Global Positioning System (GPS) measurements, for instance, are based on WGS84. For more information on map projections and geographic coordinate systems, see What are map projections?
Adding an ArcGIS Location Field to a list
To add an ArcGIS Location Field to a list, complete the following steps:
- Open the list. On the List tab, click the List Settings button. The List Settings page appears.
- Click the Create column button located below the Columns section. The Create Column page appears.
- Specify a name for the column and click ArcGIS Location. A new section, specific to creating a location field, appears at the bottom of the page.
- In this section, choose the fields containing each item's latitude (y) and longitude (x) using the drop-down menus, then click OK.
The new column is added to the list and the list can now be added to an ArcGIS Map Web Part by using the web part browse functionality. See Browsing SharePoint sites for detailed information on how to add this content to your map.
