[Talk-us] Google's Park Outlines?

[Apollinaris Schoell]

It simply depends where they got their data from. many GIS sources are available and free to use but accuracy is another thing. even some official county data can be off. have seen also big errors in the official state park data which doesn't match what is on ground and also clearly seen on yahoo aerial pics. Also most national park data is outdated and of bad quality. There are better sources available but they are not free.
google relies on automatic processing and osm strength is to have many doing survey on the ground.
