Functions

func IndexDatabaseWithFS added in v0.6.0 

func IndexDatabaseWithFS(ctx context.Context, db SpatialDatabase, index_fs fs.FS) error

IndexDatabaseWithFS will walk the files contained in 'index_fs' indexing each in 'db'

func IndexDatabaseWithIterator added in v0.1.1 

func IndexDatabaseWithIterator(ctx context.Context, db SpatialDatabase, iterator_uri string, iterator_sources ...string) error

IndexDatabaseWithIterator is a general-purpose method for indexing a `database.Spatial.Database` instance with a whosonfirst/go-whosonfirst-iterate/v2 iterator. Only records whose geometry type are 'Polygon' or 'MultiPolygon' will be indexed.

func IndexDatabaseWithReader added in v0.7.2 

func IndexDatabaseWithReader(ctx context.Context, db SpatialDatabase, r io.Reader) error

IndexDatabaseWithReader will index the data contained in 'r' in 'db'.

func RegisterSpatialDatabase 

func RegisterSpatialDatabase(ctx context.Context, scheme string, f SpatialDatabaseInitializeFunc) error

func Schemes added in v0.0.6 

func Schemes() []string
