GEOGRAPHIC DATA RESOURCE MANAGEMENT

Corresponds to the Beta BC Data Catalogue release that will go to production soon.

For the classic catalogue specific user pages see BCDC Classic Workflow.


Resources

  • See the full list of value options for drop down fields, see the BCDC Schema
  • See all documented changes in the Change Log

To add a resource:

  1. Click the Add Resource button on the toolbar at the record level.
  2. Fill out all the required fields for each resource type as described below.

Geographic datasets defined in the Catalogue, have additional attributes available through the User Interface (UI), where-as the other resource types are a subset of the fields available.

BC Geographic Warehouse (BCGW) datasets

  • Geographic Data resources type is used if they are spatially enabled or not. This is to allow for the Data Distribution Service to be configured for those datasets.
  • For Beta, the Manage BCGW Resources button has not be enabled yet.
  • To have the Download/Access button configured to pop-up the Persistent Order Widget (POW) the following must be populated:
    1. Name: “BC Geographic Warehouse Custom Download”
    2. Resource Storage Location: “BC Geographic Warehouse”
    3. Object Name: e.g., “WHSE_ADMIN_BOUNDARIES.ADM_NR_DISTRICTS_SP”

User Interface (UI) Fields

  • The following items are the field labels visible in the UI, for the database or API field names refer to the schema.

To add a resource

  1. Click the Add Resource button on the toolbar at the record level.
  2. Fill out all the required fields for each resource type as described below.

Name

  • Is the title of the resource as it will appear on the metadata record.

Resource URL

  • Is a link to a file or resource stored elsewhere, e.g., a website or FTP site.
    • For resources that are not available unless authorized a link to a webpage or form to instruct consumers how to obtain access, e.g. Request Archaeology Information

Resource File

  • Is to upload a file, e.g., CSV, directly into the Catalogue Data Store.

Note: This field may be empty for those datasets that are just metadata about a dataset or asset.


Type

  • Select Geographic Data

  • Changes:

    • Database Value: Geographic Data has changed to geographic data

Resource Description:

  • Is a detailed description of the resource.

Supplemental Information

  • Any additional relevant information about the resource can be included here.

Resource Update Cycle

  • Describes how often the resource is updated.
  • BCGW Specific: most common replication frequency is “Nightly”.

  • Changes:
    • NEW Values “Nightly” (nightly); “Unknown” (unknown)

Temporal Extent Beginning Date

  • If the dataset is temporal in nature, the start date for the period the data is captured for.

Temporal Extent End Date

  • If the dataset is temporal in nature, is the end date for the period the data is captured for.

Resource Storage Format

  • Describes the file extension for the resource.
  • BCGW Specific: select “other” (other) but others that also apply, “multiple” (multiple), “Oracle/SDE” (oracle_sde)

  • Changes:
    • NEW Values “geopackage” (gpkg); “multiple” (multiple)

Resource Storage Location

  • Is the location where the resource is stored.
  • For files that have been uploaded using the Upload File above, choose “Catalogue Data Store”.
  • BCGW Specific: select: “BC Geographic Warehouse”

  • Changes:
    • Database value all database entries are now lower case. e.g., BC Geographic Warehouse has changed to bc geographic warehouse

Spatial Datatype

  • Refers to the datatype in a database.
  • BCGW Specific: select “SDO_GEOMETRY”

    Spatial Datatype Description  
    SDE_BINARY This is the older ESRI based geometry that used to be what the BCGW prior to 2014, ESRI has moved to ST_GEOMETRY.  
    SDO_GEOMETRY This is Oracle geometry and what the BCGW and NRM uses predominately as their datatype.  
    ST_GEOMETRY This is the current ESRI based geometry.  
    N-A NEW Select if not stored in a database  
    UNKNOWN NEW Select if not unknown what spatial data type it is stored as, e.g., shape file (.shp)  

Object Name

  • Is the name of the dataset stored in a database.
  • BCGW Specific: enter the SCHEMA.OBJECT , e.g., WHSE_ADMIN_BOUNDARIES.ADM_NR_DISTRICTS_SP
    • The object name is what is used to automatically populate the metadata record with
      • The data definitions table that is extracted from the Oracle metadata.
      • For public datasets that are available in iMapBC:
        • The WMS getCapabilities request resources
        • The Network Link KML resources
        • The Preview Map details
        • The View in iMapBC button will that dataset’s specific presentations
    • Always check to make sure there is no space at the end of the value.

Projection Name

JSON Table Schema

  • NEW Field

ISO Topic Category

Resource Type

  • Is the type of resource

  • NEW Value “Not Applicable” (na)

Resource Access Method

  • Describes how the end-user can access the data.

  • Changes:

    • NEW Value “Other” (other)

Preview Information

  • BCGW Specific: these details are filled in automatically when:
    • Stored in the BC Geographic Warehouse
    • Have a public presentation in iMapBC
    • A WMS REST endpoint created
    • A Network Link KL file created.
  • These fields can be used for other purposes
  • These values populate the Preview button map and View in iMapBC -> button.

    Spatial Datatype Description
    Layer Name is the name of the BCGW object and is only different if the WMS uses a generalized dataset, e.g., WHSE_ADMIN_BOUNDARIES.ADM_NR_DISTRICTS_SP vs WHSE_ADMIN_BOUNDARIES.ADM_NR_DISTRICTS_SPG (generalized)
    Preview Latitude allows you to provide a map preview centroid latitude.
    Preview Longitude allows you to provide a map preview centroid longitude.
    Preview Map Service URL allows you to provide an alias for the map service URL.
    Preview Zoom level allows you to provide an initial zoom level for the map preview.
    Image URL shows a preview of the data as a static image.
    Link to iMap shows an interactive preview of the data in iMapBC.

Geographic Extent North/South/East/West

  • These are auto populated with the bounding box of the province.

Click Save when done

  • Additional resources can be added by repeating the process above or adding other resource types.
