The City of London has had their tree inventory information available to the public on the City's website since 2004.
It was originally developed in-house to help with our tree maintenance program.
We do not include tree condition information on the public layers.  Our tree locations are not GPS'd.
It is extremely useful for EAB management when identifying neighbourhoods that are/will be significantly impacted.  It helps residents identify if "their" boulevard tree is an ash tree.  Because lot lines are also shown on the map, residents can identify obvious city vs. private trees - this helps with tree maintenance requests and enforcement of tree by-laws.
I have attached a screen print of an example of information from our public site for a selected tree identified by a red circle with an "x" in the middle of it.
You can view London's public tree inventory website at:  http://www.london.ca/d.aspx?s=/Trees_Lawns_and_Gardens/treeinvnt.htm When you get onto this page follow the link in the following section to take you to the actual web map: Did you know that more than 120 species of trees grow on City-owned property in the Forest City? By clicking here you can use CityMap to interactively explore the inventory of trees in parks, on Thames Valley Golf Course and along boulevards and pathways as well as on City land fronting homes and businesses.
You can navigate across the City using the "Re-center" button at the top of the screen and address/streets/intersections fields on the left of the page.  To get specific tree information, click on the "Identify" button on the top of the screen then click on a specific green dot. To look at the trees and the air photo layer, you scroll down the menu bar on the left side of the page.  An interesting feature about the air photo layer is that you can look at different years of photos.  In this case, if you explore the air photo year options, you can see that the trees in the school field just below the tree information box were planted in 2001.
A GIS-based inventory is invaluable when reviewing the potential impacts of development applications, infrastructure replacement (roads, sewers, etc.) and utility projects (e.g.: replacement of natural gas lines, hydro line replacement or upgrades, telecommunications cables, etc.).

We would love to hear from other Municipal Forestry groups about their experiences / struggles with Open Data. I've only heard of Vancouver releasing their tree database to the public thus far.

Our provider added the satellite layer to the dataset view this morning. We have started to use this dataset to help citizens identify their boulevard trees by species and ID.

Is your Municipality moving in this direction? Is this a useful direction for a Municipality to move in?
