Depending on the chosen annotation type, options to customize the appearance of the annotations will become available below. For example, options to choose a particular symbol from an available library, to modify the color and the color width, or to show the coordinates next to the annotation.


Navigate through the annotations or select one on the map component.


Depending on the annotation type, change the symbol, size, position, color…


Enter the label, tooltip, hyperlink and description.


Options to adjust the transparency of all annotation icons, lines, fills or labels.

Export Annotations

The annotations can be stored in an annotation file. This annotation file is saved separately as an .o3a file and is not a fixed part of the viewer or publication.

  • Open: Open an existing HTML5 annotation file.
  • Add: Open an existing HTML5 annotation file to combine the annotations with the currently created ones.
  • Download: Download the created annotations as a *.03a file to share with colleagues. They can open or add this downloaded file then into the publication. The annotations are georeferenced, so they will appear on the same location and with the same settings as saved in the *.03a file.
