====== Orbit XML File ======

The Orbit XML File (*.oxf) is Orbit's native xml vector file storage format. \\
An OXF stores both object geometry and attribute information. 

=== Structure ===

The OXF has similar data structure capabilities as the [[209:technology:supported_formats:vector:ovf|Orbit Vector File]].

=== Reasons to use ===

  * uses the XML format which is both human and machine readable
  * takes advantage of the extended structure capabilities of the original OVF

=== Create ===

On OXF file can be created by exporting a dataset, see [[209:desktop:dataset:index|Context Menu]].

=== Legend and Georeference ===

The OXF can be accompanied by 
  * an [[209:technology:supported_formats:other:olg|Orbit Legend file]] (*.olg) to define the legend or presentation of the resource in Orbit.
  * an [[209:technology:supported_formats:other:ord|Orbit Resource Description file]] (*.ord) to define the coordinate reference system of the resource in Orbit.

=== Example ===
