Methods

readFeature(source, opt_options){ol.Feature}

src/ol/format/kml.js, line 1788

Read the first feature from a KML source. MultiGeometries are converted into GeometryCollections if they are a mix of geometry types, and into MultiPoint/ MultiLineString/MultiPolygon if they are all of the same type.

Name	Type	Description
source	Document | Node | Object | string	Source.
options	Read options. Name Type Description dataProjection ol.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.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/kml.js, line 1819

Read all features from a KML source. MultiGeometries are converted into GeometryCollections if they are a mix of geometry types, and into MultiPoint/ MultiLineString/MultiPolygon if they are all of the same type.

Name	Type	Description
source	Document | Node | Object | string	Source.
options	Read options. Name Type Description dataProjection ol.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.ProjectionLike Projection of the feature geometries created by the format reader. If not provided, features will be returned in the dataProjection.

Returns:

Features.

readName(source){string|undefined}

src/ol/format/kml.js, line 1870

Read the name of the KML.

Name	Type	Description
source	Document | Node | string	Souce.

Returns:

Name.

readNetworkLinks(source){Array.<Object>}

src/ol/format/kml.js, line 1938

Read the network links of the KML.

Name	Type	Description
source	Document | Node | string	Source.

Returns:

Network links.

readProjection(source){ol.proj.Projection}

src/ol/format/kml.js, line 2070

Read the projection from a KML source.

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

Returns:

Projection.

readRegion(source){Array.<Object>}

src/ol/format/kml.js, line 2003

Read the regions of the KML.

Name	Type	Description
source	Document | Node | string	Source.

Returns:

Regions.

readRegionFromNode(node){Array.<Object>}

src/ol/format/kml.js, line 2039

Name	Type	Description
node	Node	Node.

Returns:

Region.

writeFeatures(features, opt_options){string}

src/ol/format/kml.js, line 3029

Encode an array of features in the KML format. GeometryCollections, MultiPoints, MultiLineStrings, and MultiPolygons are output as MultiGeometries.

Name	Type	Description
features	Array.<ol.Feature>	Features.
options	Options. Name Type Description dataProjection ol.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.ProjectionLike Projection of the feature geometries that will be serialized by the format writer. If not provided, geometries are assumed to be in the dataProjection if that is set; in other words, they are not transformed. rightHanded boolean | undefined 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. decimals number | undefined Maximum number of decimal places for coordinates. Coordinates are stored internally as floats, but floating-point arithmetic can create coordinates with a large number of decimal places, not generally wanted on output. Set a number here to round coordinates. Can also be used to ensure that coordinates read in can be written back out with the same number of decimals. Default is no rounding.

Returns:

Result.

writeFeaturesNode(features, opt_options){Node}

src/ol/format/kml.js, line 3042

Encode an array of features in the KML format as an XML node. GeometryCollections, MultiPoints, MultiLineStrings, and MultiPolygons are output as MultiGeometries.

Name	Type	Description
features	Array.<ol.Feature>	Features.
options	Options. Name Type Description dataProjection ol.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.ProjectionLike Projection of the feature geometries that will be serialized by the format writer.

Returns:
