Enabling GIS (Latitude & Longitude) Features

Contents

  1. Enabling GIS for a Category
  2. Dealing with Child Categories
  3. Formatting Longitude and Latitude Values

By default GIS features (tagging geographic location by latitude and longitude) are disabled for all subject categories. You may, however, selectively enable them where appropriate. When enabled, subjects in a given category can be tagged by latitude and longitude.

Enabling GIS for a Category

To enable GIS features for a category:

1.  Select a category from the Subjects tab of a collection.

Collection -> Subjects -> Places
Actions -> Enable GIS for Category

2.  From the Actions menu in the upper -right corner, select Enable GIS for Category (To disable GIS features for a category, select Disable GIS for Category from the Actions menu:).

Dealing with Child Categories

When GIS features are enabled for a category that contains child categories (e.g., Places > Cities), any extant child categories likewise will have GIS features enabled. Furthermore, any new Child Categories which are created for a GIS-enabled (parent) category will also have GIS features enabled.

If GIS features should only apply to certain child categories, you may selectively enable GIS features on each child category, or (having enabled GIS features on the parent category), you may selectively disable GIS features as necessary.

Formatting Longitude and Latitude

Once enabled, Longitude and Latitude fields will appear at the bottom of all GIS-enabled subject attribute pages:

A GIS-enabled Subject

Longitude and Latitude values should be formatted as Decimal Degrees rather than the traditional Degree/Minute/Second format. Latitude values must fall between -90 and 90degrees, while Longitude values must fall between -180 and 180degrees. FromThePage will prevent you from inputting invalid values.

Both Latitude and Longitude values are displayed with five decimal places of precision, which is accurate to approximately one meter. Values more specific than five decimal places will be truncated to five decimal places, while values less precise will be padded with zeroes.
