Orbit Annotation File (2D)
OAF stands for Orbit Annotation File and is a file format (filename extension .oaf) developed by Orbit Geospatial Technologies for saving annotations in a file. Annotations (or Redlining) are tools to complement the map data with temporary notes or sketches.
Structure
An Annotation consists out of some Annotation Objects. An Annotation Object is a rectangle, a line, a text (See annotation types).
Reasons to use
- An Annotation can be temporary, can be stored in a file, or can be stored as attribute to a spatial object (See Dataset Structure - Naming).
- Since Orbit annotations are georeferenced, they remember exact positions and can be exchanged with other Orbit users.
Create and Update
- create a new annotation file from : Map 2D > Tools > Anno > File Access > New. Don't forget to save your anotation objects as an AOF file
- update an anotation file from : Map 2D > Tools > Anno > File Access > Open. Don't forget to save your updates.
