Working with Metadata¶
In Exchange, metadata can easily be edited for all layers, maps and documents. Keeping metadata current and thorough is important in maintaining data relevance, quality and accuracy. The more information provided in the metadata section, the more other users will understand the value of the dataset.
As you learned in Working with layers, some metadata is added when importing a layer. The basics, such as the title, abstract and category are add by the user, while information such as the projection system, bounding box coordinates, and reference links are automatically created by Exchange, and are unable to be edited by users. Additional information is added through editing the metadata.
Edit or add metadata¶
- From the search results page, click the View Details link for the map, document or layer that you’d like to edit. The details page for that resource will open.

- The raster data is part of a mosaic
- The vector has a time attribute that you’d like to enable for temporal viewing
- The raster has associated elevation information
Category - Data is divided into categories, which assists in the grouping and search of available geographic datasets. These categories correspond to those on the Exchange homepage.
Attributes (layers only) - All of the attributes for a layer will be listed. Edits can be made to the Label, Description, and Display Order fields.
Click your mouse in the field you’d like to edit, and make your changes. You can select the up or down buttons in the Display Order field to change the order of where the attribute will display in the attribute list.
