I like to share good examples of blending technology with a specific set of data. The University of Iowa has over 8000 trees of 281 species on 3 campus locations. Care of those trees is under the auspices of the Facilities Management office. They have kept a database of the trees since 1989. How can that information be shared with others?
A web app was announced 29 April 2016 on Arbor Day to make the details of each tree available to students, faculty, researchers, and the general public. Follow this link to the app. This image is an example of a small part of the campus trees map.
From the web site about the web app:
The UI Tree Inventory app delivers information about the number and location of trees and their condition, size, and species, with additional links to photos and descriptions. Users can also see if the tree was dedicated or planted as a memorial and view other designations, like state-champion status. Use the “find my location” feature on your mobile device to view information about the trees around you.
Users can drag the map, zoom in or out, and click on any of the tree symbols to bring up a window with details about that tree. What a great way to share the knowledge with everyone.

This is so cool. I’m glad they are catalogued and in a way we all can share. We often wander around wondering what kind of something that is. How wonderful to actually be able to look it up.
This is just terrific. Have you seen the New York City street tree map? One of the coolest things is being able to filter by species. I sat and played with it for a while one night. It was fascinating, just as yours is. It’s good to see technology being used in ways that are creative and accessible.
I’ve never seen the NYC trees map. I will be looking more closely at it later. Thanks.
These maps are really cool. It reminds me of when I took a botany course at my local college. They are forever changing things over there. I well remember the morning when we set off across campus to snip twigs from some trees for the herbarium we were creating, only to see our next target traveling away! They had scooped it up, root ball and all, and were moving it. There never seemed to be a good reason for this but it was entertaining~who expects trees to move?!
