This page describes the requirements and optiopns for presenting spatial data from the BC Geographic Warehouse (BCGW) in multiple web-mapping services.

Table of Contents



Spatial datasets in the BCGW may be configured for web-mapping services, this requires:

  1. A published spatial dataset in the BC Geographic Warehouse.
  2. A metadata record.
  3. A profile defined as one of the Security options below.
    • Named Users is the only profile that requires additional configuration.
  4. A presentation layer as created with the Layer File Presentation document
    • And published through to iMapBC production.


  • Large datasets or with wide variety of size differences may see perfomance issues.
    • For certain datasets, like regional boundaries, a generalized dataset can be created to be used in web-mapping service.
