MATHEMATICA IMPORT/EXPORT FORMAT
KML (.kml, .kmz)
- Import["file.kml"] imports a KML file and returns a combined rendering of all graphics layers.
- Export["file.kml", expr] exports the data to KML.
-
- Import["file.kml"] returns a Graphics object.
- Import["file.kml", "elem"] imports the specified element from a KML file.
- Import["file.kml", {{"elem1", "elem2", ...}}] imports multiple elements.
-
- Export["file.kml", {layer1, layer2, ...}, {"KML", "Data"}] exports expressions representing KML features to a file.
-
- See the reference pages for full general information on Import and Export.
- ImportString and ExportString support the KML format.
- General Import elements:
-
| "Elements" | list of elements and options available in this file |
| "Rules" | full list of rules for each element and option |
| "Options" | list of rules for options, properties, and settings |
-
- Data representation elements:
-
| "Data" | rule-based representation for each feature of a KML archive |
| "Graphics" | all layers combined into a single Graphics object |
| "GraphicsList" | list of graphics representing the layers of a KML archive |
| "ImageOverlays" | raster image overlays |
- Import by default uses the
element for the KML format.
- Import with element
gives the combined graphics contents as vector and raster graphics.
- Import["file", "Data"] returns an expression of the form
. Individual layers are given as a list of rules representing the geometry as well as numerical and textual information associated with the features.
- The
element supports the following features on Export:
-
| "ExtendedData" | extended data given as lists of rules |
| "Geometry" | list of Line, Point, and Polygon primitives |
| "LabeledData" | data given as a list of rules |
| "LayerName" | layer given as a string |
| "NetworkLinks" | list of strings representing links |
| "Overlays" | rules representing ground overlays |
| "PlacemarkNames" | names of placemarks given as strings |
- Meta-information elements:
-
| "LayerNames" | all layer names, given as a list of strings |
| "LayerTypes" | what graphics primitives comprise each layer |
| "SpatialRange" | range of geographic coordinates, typically given in decimal degrees |
- Geographic coordinates in KML files always refer to the WGS84 datum.
- General rendering options:
-
Import all layers from a KML file:
| Out[1]= |  |

| Out[1]= |  |
Import the layer names:
| Out[1]= |  |
Import city information:
| Out[1]= |  |
Show a list of all import elements available for this file:
