====== Vector Resources in 3DM Viewer ======

This page describes the concepts of Vector Data in 3DM Viewer 

==== Supported Vector Resources Types ====

Supported Vector Resource Storage formats, see [[262:technology:supported_formats:index|]].

==== Static and Dynamic Resources ====

Related to loading of objects and labels: 
  * Orbit Vector File (OVF) resources are loaded as static resources. The Viewer loads the entire resource at once at first use. 
  * Orbit Vector Tile (OVT) resources are loaded as dynamic resources. The viewer loads the relevant tiles only. Relevant tiles are derived from the Viewer's Focus Coordinate. 

==== Read-Only and Read-and-Write =====

Related to editing Vector Objects and Attributes: 
  * When opened in the 3DM Viewer, Orbit Vector File (OVF), Orbit Vector Tile (OVT) and KML/KMZ resources are Read-Only.
  * Orbit Database (ODB) and WFS-T resources can be configured to be Read and write.

==== Attribute Search ====

Related to the attribute value search: 
  * OVF and OVT resources support querying of String, Integer, and Boolean attribute values. No support to search Float attribute value. 
  * ODB and OWFS resources might have additional support for Float values, depending on the backend server or database. 

==== Vector Dataset Legend ====

The default legend is prepared with the Orbit Desktop Tools.
