OpenStreetMap
Not a great fan of of multi tagging a Way. But it has it's uses WITH CAUTION.
My Comment is targeted in particular at the practice I have noticed of Tagging an Administrative Boundary as a River, or Highway.
As A river.. it is a darn quick and easy way of placing many KM of stream and river data onto the MAP.. BUT.. PLEASE Check what is being marked. The Admin Boundary's Also Follow Roads.. And if your naming the rivers.. be careful that the 2 rivers don't merge and the boundary doesn't follow the joining stream..
As for the tagging a Admin Boundary as a road.. Well the boundaries can be better than 30 years old, or follow the Commonwealth/state Land Corridor for the road.. THE ROAD MAY NOT BE THERE.. certainly makes it difficult when you survey a road and need to move it the 10, 100m or more.. you know make the road follow it's current course and not look like the crappy google maps.
On the subject of Google Maps... I play here on OSM because the Google maps for my area of the world is WRONG.. well has a lot of errors. we can bring a map that is not only open source but has the stupidities removed.
Am I trashing anyone with these comments? well 90% is directed at myself as a reminder..
I will be pleased when i am back in an environment where I can use JOSM again.. that is on my PC and My network..

The ABS data is the best we have for rivers in most parts of Australia even if it isn't entirely accurate.

The ABS data is a lot better than landsat tracing or other imports eg vmap for the places like the Murrumbidgee and Lachlan. I haven't used ABS data for roads.

Both comments regarding the ABS for the rivers is true.. very true I have used it myself.. with regard to rivers .. when it is being used ppl do need to check that that the boundary didn't switch from River to Road.. But to be using the ABS for roads.. very iffy.. a/ without local knowledge b/ confirmation of survey.. and even then it adds to the future effort if the road changed (and the ABS boundry does not..) rivers take a lot longer to change course ;)
