Class: GMLBase

ol.format.GMLBase

Abstract base class; normally only used for creating subclasses and not instantiated in apps. Feature base format for reading and writing data in the GML format. This class cannot be instantiate, it contains only base content that is shared with versioned format classes ol.format.GML2 and ol.format.GML3.

Name Type Description
options

Optional configuration object.

Name Type Description
featureNS string

Feature namespace.
featureType string

Feature type to parse.
srsName string experimental

srsName to use when writing geometries.
surface boolean | undefined

Write gml:Surface instead of gml:Polygon elements. This also affects the elements in multi-part geometries. Default is false.
curve boolean | undefined

Write gml:Curve instead of gml:LineString elements. This also affects the elements in multi-part geometries. Default is false.
multiCurve boolean | undefined

Write gml:MultiCurve instead of gml:MultiLineString. Since the latter is deprecated in GML 3, the default is true.
multiSurface boolean | undefined

Write gml:multiSurface instead of gml:MultiPolygon. Since the latter is deprecated in GML 3, the default is true.
schemaLocation string | undefined

Optional schemaLocation to use when writing out the GML, this will override the default provided.

Name Type Description
dataProjection ol.proj.ProjectionLike

Projection of the data we are reading. If not provided, the projection will be derived from the data (where possible) or the defaultDataProjection of the format is assigned (where set). If the projection can not be derived from the data and if no defaultDataProjection is set for a format, the features will not be reprojected.
featureProjection ol.proj.ProjectionLike

Projection of the feature geometries created by the format reader. If not provided, features will be returned in the dataProjection.
Returns:
Features.
