If I had to guess, I'd say that Waze's water data came from the dataset you can see at http://viewer.nationalmap.gov/viewer/nhd.html?p=nhd .AndyPoms wrote: Water: I posted above that we were working on figuring out what was there & what wasn't in CT. We did the original work on the guidelines for CT when there were issues with the water layer & we didn't want to mess with it. I would certainly agree (as would the other CT users) that if it's not on the water layer, and is significant it should probably be mapped - HOWEVER, we need to talk to Waze about this as they may be adding other water bodies (they are mostly working on coastlines now) and un-submerging roads.
We can see two different generated static vector images generated from this data on the Livemap and on the client...
I'd guess that the one on the Livemap got slightly higher granularity when generated, say...to make sure that water objects that are 75x75ft or larger show up on the map, in general - and it has names associated with the objects that are exactly the same as they appear in the NHD data. (E.g. 'Lk Fenwick' at http://www.waze.com/livemap/?zoom=15&la ... yers=BTTTT ). The one in the Waze client is slightly LESS granular...its accuracy is to objects about 100x100ft, and to the best of my knowledge, those names were NOT imported or if they were, they're not visible. Stuff that's smaller overall, like small rivers or creeks, don't show up at all by either standard even though they are present and named in the NHD.
So I guess with respect to water layers I would have two questions for the folks generating the water tiles:
1. Can we expect that the granularity will remain the same in the future - so if we want say, creeks that we can't see in the client or Livemap today, that we SHOULD add them?
2. We can't see names of objects on the water layer in the client, imported as-is from NHD, or otherwise. Should we be expecting to but can't? (The whole reason I was adding larger bodies of water in WME was for better shoreline accuracy, and so a name of a water body DID show up as one travels.)
