====== Annotations Overview ======

This page describes the general operations and principles of Annotations. \\
More information about all features of the Annotation Tools Sidebar, see: [[2210:desktop:tools:annotations|]].
===== What are annotations ? =====

Annotations are tools to complement the map data with temporary **notes or sketches**. Orbit provides a range of annotation types that can be stored in an annotation file or as attribute (only in OVF format). Since Orbit annotations are **georeferenced**, they remember exact positions and can be exchanged with colleges.


==== Annotations structure ====

An Annotation consists out of some Annotation Objects.  An Annotation Object is a rectangle, a line, a text (See [[2210:desktop:tools:annotations|annotation types]]).  \\  
An Annotation can be temporary, can be stored in a file, or can be **stored as attribute to a spatial object** (See [[2210:desktop:dataset:contents:naming|]]).

==== Exchanging Annotations ====

Since annotations are georeferenced, you can easily **exchange** your remarks **with a colleague**. Just save the annotation in a file, and email the *.oaf file. Your colleague can open this file using the Open Annotation File function.

<note>
Since Orbit can work with dynamic [[2210:desktop:dataset:legend:parameters:symbol_library|Symbol Libraries]], make sure that your colleague has access to the symbols you used in your annotation properties.
