[OSGeo-Discuss] Open "StreamMap"?

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
