Maproulette Tags
MapRoulette Tags, often called MR Tags, are primarily used for custom filtering and grouping tasks within a challenge. Currently, MR Tags are exclusive to MapRoulette and are not utilized or visible in other editors. If MR Tags are needed, the challenge manager will typically provide instructions on how to implement them within a task’s description.
How the Data is Used and Example of Useful Tag Use
For example, if you have a challenge in an area where there may not be enough high-quality imagery available for mappers to complete all the tasks successfully, you can ask mappers to add a tag like bad-imagery when they encounter that situation. Later, when you download the tasks export, you can analyze the tags to find out which areas lacked good imagery, and potentially use that information to start something like an OpenDroneMap + OpenAerialMap project 🙂.
Preferred MR Tags
Set in the challenge editor, these are the tags that will be recommended to mappers and reviewers if they try to add MR Tags. There are two types of preferred tags:
- Preferred MR Tags: Recommended in the task completion workflow, which is the workflow that most regular mappers use.
- Preferred MR Review Tags: Recommended in the task review workflow, which is the workflow the reviewers use.
Restricting MR Tags
As per the editor settings, if the ‘Allow other tags during task completion’ or review is marked as ‘No’, the only tags that the user can input are the ones from the pool of tags the challenge manager added.
Adding MR Tags
Mappers and reviewers can add MR Tags from the completion widget. If there are currently no MR Tags on a task, the ‘Add MR Tags’ button will be displayed. This button opens up a modal that allows the user to modify the displayed tags.
MR Tags can also be added in the completion modal:
