Name Type Description
options

Optional configuration object.

Name Type Description
featureNS Object.<string, string> | string | undefined

Feature namespace. If not defined will be derived from GML. If multiple feature types have been configured which come from different feature namespaces, this will be an object with the keys being the prefixes used in the entries of featureType array. The values of the object will be the feature namespaces themselves. So for instance there might be a featureType item topp:states in the featureType array and then there will be a key topp in the featureNS object with value http://www.openplans.org/topp.
featureType Array.<string> | string | undefined

Feature type(s) to parse. If multiple feature types need to be configured which come from different feature namespaces, featureNS will be an object with the keys being the prefixes used in the entries of featureType array. The values of the object will be the feature namespaces themselves. So for instance there might be a featureType item topp:states and then there will be a key named topp in the featureNS object with value http://www.openplans.org/topp.
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.
