If a working map has been already created during the mapping phase (and optionally geo-referenced during the geo-referencing phase), to add new features to an existing map you simply have to:
- Launch Dragonfly.
- Load the map of interest.
- Perform an additional mapping with the new lighting conditions, and following exactly the same instructions followed to create your first map.
- Save the progresses as a NEW map choosing a meaningful name and description.
Why we encourage you to save the progresses as a NEW map instead of UPDATING an existing map?
Because by doing so you can start again from the previously saved map in case of problems during the mapping process.
