- kml_file_to_georss(+KMLfile) is det
- kml_file_to_georss(+KMLfile, +RDFfile) is det
- Converts the contents of an KML file into GeoRSS RDF in
the RDF database of Prolog.
The Geometries are converted to GeoRSS properties and values.
Documents, Folders, etc. are ignored.
MultiGeometry objects are expanded into separate simple
Geometries.
Geometries with an XML ID are assigned that ID as URI,
other Geometries are assigned a RDF blank node.
The kml:name and kml:description are translated to RDF
properties.
- georss_to_kml_file(+KMLfile) is det
- georss_to_kml_file(+KMLfile, +Options) is det
- Converts the contents of the RDF database of Prolog
into a KML file without style information and without
Folders.
kml:name and kml:description properties in the RDF database are
converted to their KML counterparts.
Options can be used to pass Document level options,
for example, the name of the dataset. Options can also include
a
graph(Graph)
option to specify which RDF named graph should
be converted to KML.
- kml_shape(?Stream, ?Shape) is semidet
- kml_shape(?Stream, ?Shape, ?Attributes, ?Content) is semidet
- Converts between the KML serialization of a shape and its
internal Prolog term representation.
Attributes and Content can hold additional
attributes and XML content elements of the KML, like ID, name,
or styleUrl.
- kml_uri_shape(?KML, ?URI, ?Shape) is semidet
- Converts between the KML serialization of a URI-shape pair and its
internal Prolog term representation.
It is assumed the KML Geometry element has a ID attribute
specifying the URI of the shape. e.g.
<PointID="http://example.org/point1"><coordinates>52.37,4.89</coordinates></Point>
- kml_file_shape(+File, ?Shape) is semidet
- kml_file_shape(+File, ?Shape, ?Attributes, ?Content) is semidet
- Reads shapes from a KML file using kml_shape/2.
kml_file_shape/4 also reads extra attributes and elements of
the KML Geometry.
e.g. <Point targetId="NCName"><extrude>0</extrude>...</Point>
will, besides parsing the Point, also instantiate Content with
[
extrude(0)
] and Attributes with [targetId('NCName')
].
- kml_file_uri_shape(+File, ?URI, ?Shape) is semidet
- Reads URI-shape pairs from File using kml_uri_shape/2.
- kml_save_header(+Stream, +Options) is semidet
- Outputs a KML header to Stream.
This can be followed by calls to kml_save_shape/3 and
kml_save_footer/1.
Options is an option list that can contain the option name(Name)
specifying the Name of the document.
- To be done
- - options to configure optional entities, like styles
- kml_save_shape(+Stream, +Shape, +Options) is semidet
- Outputs a KML serialization of Shape to Stream.
This can be preceded by a call to kml_save_header/2 and
followed by more calls to kml_save_shape/3 and a call to
kml_save_footer/1.
Options is an option list that can contain the option
attr(+List)
or content(+List)
that can be used to add
additional attributes or xml element content to a shape.
This can be used to specify things like the ID or name.
Layout elements, like Placemark and Folder, have their
own separate extra attributes to supply additional
attributes and content.
These can contain the special terms geom_attributes and
geom_content that pass their content to the shape contained by
the Placemark.
For example, rendering a Placemark with the ID
"placemark12" of an extruded Point shape with its URI as name of
the Placemark and as ID of the shape and an additional styleUrl
works as follows:
kml_save_shape(Stream,
placemark(point(53.0,3.9),
[ id(placemark12),
geom_attributes([ id(URI) ])
],
[ name(URI),styleUrl(URI),
geom_content([ extrude(1) ])
]),
[]).
- kml_save_footer(+Stream) is det
- Outputs a KML footer to stream Stream.
This can be preceded by calls to kml_save_header/2 and
kml_save_shape/3.
