Patrick Barry, the founding member of TreeKIT’s Advisory board, has added an important new map feature — a “legend” in and of itself (pun intended).

At long last, this legend helps explain the following:

• When zoomed out, the map displays block edges color-coded by tree density.
• When zoomed in, individual trees become visible. Trees are classified as “Alive,” “Dead,” “Stump,” or “Empty Bed.” “Alive” trees are graded into six size classes by diameter at breast hight.
• When closely zoomed in, individual treebed rectangles become visible.

Thank you Patrick for this great addition to the map!

We’re using Tilemill to create maps of the data mapped by TreeKIT over the past year and a half. Trees are sized according to their trunk size, red indicates a standing dead tree, orange indicates a stump, and black indicates an empty bed ready to be replanted.

All of Prospect Heights, and portions of Woodside, Sunnyside, and Astoria are complete — which neighborhood will be next?

Our friends at Azavea have expanded the Urban Forest Map code base into what is now known as Open Tree Map. We are delighted to be among their partners!
