Class: GML

ol .format.GML

Feature format for reading and writing data in the GML format. Currently only supports GML 3.1.1 Simple Features profile.

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.

readFeatures(source, opt_options){Array.<ol.Feature>} src/ol/format/gmlformat.js, line 1061

Name	Type	Description
`dataProjection`	ol.proj.ProjectionLike \| undefined	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 \| undefined	Projection of the feature geometries created by the format reader. If not provided, features will be returned in the `dataProjection`.

Features.

writeFeatures(features, opt_options){Node} src/ol/format/gmlformat.js, line 1730

`featureProjection`	ol.proj.ProjectionLike	Projection of the feature geometries that will be serialized by the format writer.
