Hi Charlie,
I like your idea, but there are many issues to discuss.
1. What is the goal?
Depending on users interest (hydrologists, biologists, ..), "average"
stream can be represented as line or polygon.
Set of attributes depends on user needs. Even simple water level changes
in time. Without some standarisation (mean yearly level?) this will be
mixture of everything. And such attributes are not easy to get.
Geometry based on recent ortophotomaps with basic set of attributes
(stream name(s); some "average" discharge and velocity?) could be start
point.
2. Relation to OSM.
It can be seen as subset or extension of OSM. And probably those two
sets will be used together. Close cooperation with/within OSM?
3. Additional data
What about water level gauge stations?
Anyway - great idea!
regards,
Robert

Hi,
I find myself wondering if there is a possibility of starting an "open
stream map" project in a similar way to open street map? With the idea
that this might be connected to an invasive plant species effort too...
It is an interesting idea -- roads are relatively stable. Streams have
additional attributes, like water levels.
Any reactions or ideas on how this might be started?
Cheers
Charlie Schweik
