Geospatial data resources / collections.

For GoKoala devs: If you want to implement collections support in one of the OGC building blocks in GoKoala (see ogc package) you'll need to perform the following tasks:

Config:

• Expand / add yaml tag in engine.Config.OgcAPI to allow users to configure collections

OpenAPI

• Materialize the collections as API endpoints by looping over the collection in the OpenAPI template for that specific OGC building block. For example for OGC tiles you'll need to create /collection/{collectionId}/tiles endpoints in OpenAPI. Note /collection/{collectionId} endpoint are already implemented in OpenAPI by this package.

Responses:

• Expand the collections and collection templates.
• Implement an endpoint in your specific OGC API building block to serve the CONTENTS of a collection (e.g. /collection/{collectionId}/tiles)

Testing:

• Add unit tests

Types

type Collections

type Collections struct {
	// contains filtered or unexported fields
}

func NewCollections

func NewCollections(e *engine.Engine) *Collections

NewCollections enables support for OGC APIs that organize data in the concept of collections. A collection, also known as a geospatial data resource, is a common way to organize data in various OGC APIs.

func (*Collections) Collection

func (c *Collections) Collection() http.HandlerFunc

Collection provides METADATA about a specific collection. To get the CONTENTS of a collection each OGC API building block must provide a separate/specific endpoint.

For example in: - OGC API Features you would have: /collections/{collectionId}/items - OGC API Tiles could have: /collections/{collectionId}/tiles - OGC API Maps could have: /collections/{collectionId}/map - OGC API 3d GeoVolumes would have: /collections/{collectionId}/3dtiles

func (*Collections) Collections

func (c *Collections) Collections() http.HandlerFunc

Collections returns list of collections
