@Zlima12, a lot can be learned just by looking at the ground cover. For example Central Park has lots of fields, sports fields, tennis courts, gardens, monuments...etc. While lets say Harriman for example, even if I had never been there, looking at the map I would see that there are a lot of forest cover, mountains, lakes, woods roads. Regardless of park or nature preserve, if you see sports fields, tennis courts, fountains, monuments...etc, you can automatically tell it is a developed park. While if you see lot of hiking trails, and forest cover, it is safe to assume it is for hiking.

Suppose you did not know what Cranberry Lake was, just by looking at the features within the boundary you would be able to know a lot of information about what is in there.
