Inventorying Your GIS Data

PLEASE NOTE: You have two options for inventorying your data layers. The first is by manually entering the information using the link to My Data Layers. The other is a more automated approach that is described under the Harvesting link.

For most fields you select a response from a drop-down list (select the answer that most accurately represents your data). The basic inventory-level data records are described by 8 basic metadata-derived fields:

1. Title (automatically-generated)
2. Progress
3. Source
4. Scale
5. Content Date
6. Update Frequency
7. Geography (auto-populated from Geography profile but can be altered)
8. Layer Description

BEST PRACTICE: We strongly encourage you to add a detailed description to help others better understand important details about your data.

Users are also encouraged to provide information in 4 additional areas where applicable:

Persistent Metadata URL (this is a complete URL that links to a more comprehensive FGDC metadata record on another web site)

Web Service URL (this is a complete URL to access a web map service view or web feature service that provides access to this data)

Archive Information (checking Yes will cause additional fields to appear that will provide details on your archives)

Federal Grant Money (some Federal agencies require a data plan for their grant programs and if you check yes to this field, your report can serve as that data plan)

Certain data layers have additional attribute information that is automatically inserted into the metadata and System reports to make them more useful to a wide range of users. Those layers include imagery, parcels, road centerlines, addresses, land use and land cover, digital elevation models and hydrography.

Users estimate that it takes between one and three minutes to inventory each individual data layer.

Step 1) Select an ISO Data Category and the individual layers associated with that Category will appear below. If you don't know which category is associated with the correct data layer name, you can click on "Search for a data layer" and enter a keyword to find the appropriate data layer name in the GIS Inventory. Simply select the appropriate layer that appears.

Step 2) Click on the appropriate data layer under "Document a Data Layer" that you want to inventory. A window with the data entry form will pop-up.

Step 3) Complete the information in the pop-up window and click on "Save" button at the top of the window. Your information will now appear on the Data Layers Page.

Step 4) If you have more than one data set for the layer listed, you can simply click the "+" sign next to the layer name to open another entry form for the same data layer.

BEST PRACTICE: You should only inventory data that you or your organization has created or substantially modified, either directly or through contractual services. You should not document data produced by other entities that you simply use in your operation.

Custom Geography

In the My Geography section, you defined a default geographic extent that is automatically assigned to GIS data that you inventory. If you have a different geographic extent for a specific data layer, you can create a new geography in the "My Geography" section of your account.

Changing Geography

You can create multiple geographies and apply them, as appropriate, to individual data layers.
1. If you have already created a new geography, you can re-use it by selecting its alias name from the drop-down list.
2. You must return to the My Geography section to edit a saved geography.

PLEASE NOTE: If you delete a custom geography, the system will automatically assign your default geography to all data layers that were associated with it.
