  • Import fully supports the GPX format Version 1.1.

Background & Context

    • GPX global positioning data.
    • Standard format for exchanging GPS location data.
    • Stores GIS data recorded with GPS devices.
    • GPX is an acronym for GPS Exchange Format.
    • XML format.
    • Introduced in 2002.

Import

  • Import ["file.gpx"] imports a GPX file and returns a combined rendering of all graphics layers.
  • Import ["file.gpx"] returns a GeoGraphics object.
  • Import ["file.gpx","elem"] imports the specified element from a GPX file.
  • Import ["file.gpx",{{"elem1","elem2",}}] imports multiple elements.
  • See the following reference pages for full general information:
  • Import import from a file
    CloudImport import from a cloud object
    ImportString import from a string
    ImportByteArray import from a byte array

Import Elements

  • General Import elements:
  • "Elements" list of elements and options available in this file
    "Summary" summary of the file
    "Rules" list of rules for all available elements
  • Data representation elements:
  • "Data" graphics primitives for each layer
    "Graphics" all layers combined into a single GeoGraphics object
    "GraphicsList" list of graphics representing the layers of a GPX archive
    "TabularAssociation" association of layer names and Tabular objects
  • Import by default uses the "Graphics" element for the GPX format.
  • Import ["file.gpx","Data"] returns an expression of the form {layer1,layer2,layer3}. Individual layers are given as a list of rules representing the geometry as well as numerical and textual information associated with the features.
  • Meta-information elements:
  • "Comments" description of the file as a string
    "LayerNames" all layer names, given as a list of strings
    "Metadata" author and copyright information
    "Name" name given in the file
    "SpatialRange" range of geographic coordinates, typically given in decimal degrees
  • Geographic coordinates in GPX files always refer to the WGS84 datum.
