Mapping remotely

You are more than welcome, as always to join us remotely in helping to fill the gaps in the missing maps.

The tutorial for new mappers will start at approximately 1830 and will be broadcast via a link TBC later today.

Mapping tasks

Tasks for the night will include:

Task 748ː CAR Buildings and residential areas only (for new mappers)

Task 749ː CAR Road networks only (needs finishing off)

Task 740ː Leer to the north

Task 728ː Rwanda (for mappers with some experience)

Take a look here for photos of BANGASSOU and LEER and their surrounding areas. These are to try and help give the aerial photos you are tracing from some context...


The following links will help you get started and should answer a lot of technical questions you may have:

The HOT Tasking Manager

Mapping with iD (web-based and simpler, but slower and not as fun)

Mapping with JOSM (JAVA software needed, but faster and way more fun)


If you want to get in touch, please do so with the hashtag #MissingMapsHelp and, if they are free, someone will get in touch.

Mapper survey

If you mapped for the Missing Maps today, we'd love to know more about you! It'll take less than five minutes to fill in this survey

Bugs, problems and learnings


Several people signed up with tickets to map remotely. Original invite should make the distinction clear and refer remote mappers to the event wiki page for more information.
