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

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

=== Structure ===

An Orbit Vector Tiled file has similar data structure capabilities as the [[112:technologies:resources:vector:ovf|Orbit Vector File]], additionally both its spatial and attribute component are indexed.

=== Reason to use ===

The OVT is optimized for fast viewing and querying of vector data. The format is platform independent. The dataset is read only, both spatial and attribute component cannot be edited. \\
An OVT is extremely powerful in combination with [[112:orbit_desktop:datasets:general:index|dataset scale range limits]] to handle fastly large vector resources with minimum memory and cpu requirements.

=== Create and Update ===

  * Create by export datasets, see [[112:orbit_desktop:datasetlist:dataset:context_menu|]]
  * Create by xport selection, see [[112:orbit_desktop:inspector:object:index|]]
  * Update : An OVT is read only, to edit export to OVF, updated and export back to OVT.

=== Legend and Georeference ===
