[Talk-us] California is too big ;)

I detested the “Six Californias” when it was being proposed as a ballot measure. Perhaps that is flavoring my response, but at one time or another I’ve generated topo maps for areas that lie within four of those six divisions so it would be a bit of a hassle for me to have that.

If a split need be made I would prefer a single one which logically would be on a north-south basis, probably based on the number of OSM objects but following some county boundaries that can be listed in the description.

In any case, I assume a good description of the extract boundaries will be provided (unlike Maps.me and now Osmand where the names of the sub-state areas are all that is provided and it is not clear to me the exact extent of coverage is for any given map download).

At present there is a us-west extract covering basically the Rocky Mountain states and west. Last I checked it was a bit over twice the size of California alone. Along that same line, would the current extract for California continue in addition to the sub-state extracts? If so, then I will withdraw my opinion on where the state extracts should be split as I can continue, at least for the while, with using the full state data.

Thank you for your attention to this and for your organization making these extracts available!

Cheers!
Tod
