Methods

readFeature(source, opt_options){ol.Feature}

src/ol/format/gpxformat.js, line 434

Read the first feature from a GPX source.

Name	Type	Description
source	ArrayBuffer | Document | Node | Object | string	Source.
options	Read 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:

Feature.

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

src/ol/format/gpxformat.js, line 467

Read all features from a GPX source.

Name	Type	Description
source	ArrayBuffer | Document | Node | Object | string	Source.
options	Read 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.

readProjection(source){ol.proj.Projection}

src/ol/format/gpxformat.js, line 501

Read the projection from a GPX source.

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

Returns:

Projection.

writeFeatures(features, opt_options){string}

src/ol/format/gpxformat.js, line 856

Encode an array of features in the GPX format.

Name	Type	Description
features	Array.<ol.Feature>	Features.
options	Write 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. rightHanded boolean | undefined experimental When writing geometries, follow the right-hand rule for linear ring orientation. This means that polygons will have counter-clockwise exterior rings and clockwise interior rings. By default, coordinates are serialized as they are provided at construction. If true, the right-hand rule will be applied. If false, the left-hand rule will be applied (clockwise for exterior and counter-clockwise for interior rings). Note that not all formats support this. The GeoJSON format does use this property when writing geometries.

Returns:

Result.

writeFeaturesNode(features, opt_options){Node} experimental

src/ol/format/gpxformat.js, line 867

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

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. rightHanded boolean | undefined experimental When writing geometries, follow the right-hand rule for linear ring orientation.
