New York City is filled with parks, trees, and farmers markets. Not the image you had in mind when someone references New York City. Well, Rentenna.com can show you that image. Rentenna allows a person to view apartment ratings, reviews, and rentals in different cities across the nation. Its newest feature is called the Green Heatmap. Currently, the map is only available for New York City and Brooklyn, New York. A detailed map of the area displays high concentrations of street trees in bright green while tree and market sign icons indicate parks and farmer’s markets. Cities like D.C. , Baltimore, and Richmond will hopefully see a map of their area soon.
