[OSM-talk] The problem of mapping temporary features

[Rob Nickerson]

Hi all,

Back in January/February of this year parts of Somerset, UK were flooded.
This data was added to OpenStreetMap. Today a diary post on OpenStreetMap
pointed me to a  map rendering (MapSurfer). The map still shows the flooded
area despite the fact that the waters have now retreated and the data has
been removed from OpenStreetMap [1].

This is a good example of why we need to be very careful mapping temporary
features. Many data users update infrequently.

Suggestions of how to get the balance right are welcome.

Regards,
Rob
