Class: GML3

ol.format.GML3

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

new ol.format.GML3(opt_options) experimental

src/ol/format/gml/gml3format.js, line 37
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.

Methods

readFeatures(source, opt_options){Array.<ol.Feature>} inherited

src/ol/format/gml/gmlbaseformat.js, line 540

Read all features from a GML FeatureCollection.

Name Type Description
source ArrayBuffer | Document | Node | Object | string

Source.

Options.

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.

writeFeatures(features, opt_options){string}

src/ol/format/gml/gml3format.js, line 1279

Encode an array of features in GML 3.1.1 Simple Features.

Name Type Description
features Array.<ol.Feature>

Features.
options

Options.

Name Type Description
dataProjection ol.proj.ProjectionLike

Projection of the data we are writing. If not provided, the defaultDataProjection of the format is assigned (where set). If no defaultDataProjection is set for a format, the features will be returned in the featureProjection.
featureProjection ol.proj.ProjectionLike

Projection of the feature geometries that will be serialized by the format writer.
Returns:
Result.

writeFeaturesNode(features, opt_options){Node} experimental

src/ol/format/gml/gml3format.js, line 1290

Encode an array of features in the GML 3.1.1 format as an XML node.

Name Type Description
features Array.<ol.Feature>

Features.

featureProjection ol.proj.ProjectionLike

Projection of the feature geometries that will be serialized by the format writer.
Returns:
Node.

writeGeometryNode(geometry, opt_options){Node} experimental
