====== Orbit Vector File Tiled ======

The Orbit Vector Tiled file (*.ovt) is Orbit's native tiled vector file storage format. \\
An OVT stores object geometry, attribute information and indexes on both components. 

=== Structure ===

An OVT has similar data structure capabilities as the [[195:technology:supported_formats:vector:ovf|Orbit Vector File]]. Additionally both spatial and attribute component are indexed. \\
An OVT is read only.

=== Reason to use ===

The OVT is optimized for fast viewing and querying of vector data. The format is read only and platform independent. \\
An OVT is extremely powerful in combination with [[195:desktop:dataset:general|dataset scale range limits]] to handle large vector resources in the most efficient way using a minimum of memory and cpu. It is no issue to load a resource over 5 GB file size, having more than 5,000,000 objects.

=== Create and Update ===

  * Create by export datasets, see [[195:desktop:dataset:index|Context Menu]]
  * Create by export selection, see [[195:desktop:tabs:inspector|]]
  * To Update, export OVT to OVF, make changes and export back to OVT.

=== Legend and Georeference ===

The resource can be accompanied by an [[195:technology:supported_formats:other:olg|]] and [[195:technology:supported_formats:other:ord|]].
