How to map seasonal roads and rivers in Benin
Posted by Maarten van der Veen on 17 August 2015 in English.For a Missing Maps event in Amsterdam and London, next wednesday august 19th, the Netherlands Red Cross is going to map the south of Benin, specifically some villages prone to flooding and Porto-Novo.
Due to this flooding, roads are used in two ways during the year:
- Dry season: normal vehicles on road
- Wet season: boats on these same roads, which are then flooded
We are trying to decide how to tag these roads:
- tag the roads as ‘highway residential’
- add the tag ‘seasonal=yes’ AND/OR
- add the tag ‘flood_prone=yes’
Additionally, the rivers have specific docking areas for canoes. We are still deciding whether to map these. And if so, what are the proper tags.

Hi Peter, There is an OSM community in Cotonou; it is not so large, but they’re technically very good and motivate mapping Benin. We have planed to join you and the US Peace Corp also to coordonate some activities, We can make this happen with this missing map event. What do you think ?

As far as I know, there’s no good tag for a canoe launch.

Hi, conditional access should help you for seasonal road : osm.wiki/Conditional_restrictions I suppose a boat restriction and car restriction should be allright.
Less generic is seasonal’s tag, but I like it less : seasonal=*
About docks for canoes, you should be more specific, is it a place to rent canoe ? or only to park ? Like a canoe parking ? Many possibilities, depending on the uses/services
You should talk about it in mailing lists !
