Government No Auth Free & Open open_data

The Geomark Web Service allows you to create and share geographic areas of interest over the web in a variety of formats and coordinate systems. This service is especially helpful when you need to share an area of interest with people who require that the data be in a different format, or they use different mapping software. Please note that you may experience issues when submitting requests to the delivery or test environment if using this [OpenAPI specification](https://github.com/bcgov/api-

No authentication requiredFree to use with no key needed.

Sample Requests

GET Get information about a particular geomark

The attribution can be downloaded as a info file format. The download files can then be processed by a client application to access the geomark info fields and to get the URLs to the geometry download resources.
