Hi Travis:

As requested, here is the link to our private ash tree mapping project ( I credit the City of Milwaukee, Dave Sivyer, for introducing us to this method). Please keep in mind this not accepted mainstream technology for trees as of yet.

Hi Folks,

Thanks for all the awesome links.

John, I had to remove the word "this" at the end of your link (maybe "this" was isolated to my workstation) and then it worked beautifully. I shortened it a bit, it is definitely worth a look.

In particular, I like the way you are showing the public your management of EAB in your Ash inventory. We have yet to integrate our Georeferenced trees into a true GIS asset management system. I can see this as being invaluable for accurate outbreak and quarantine management. I'm also really impressed with the classification of probable Ash trees. Can you tell us more about this type of spectral analysis? Can you provide a link to the methodology? It seems to me that classification in this way would be very important seeing as most municipalities have limited resources to track Public trees let alone Private. A standard methodology for spectral classification of species by aerial or satellite imagery would be indispensible.

Ivan, I had some difficulty using the mapping interface to see anything other than where the trees were located. Nonetheless, similar to John's example I like that your GIS has many layers of data available for overlaying. I think as our Open Data moves forward, being able to see all the different layers in a format similar to your view would be great for the public (and Urban Foresters in the field)

Karen, You've pointed out a weakness in our dataset, or at least a weakness in the way we describe how to use our dataset. In order to see distribution you need to zoom down to near street level. Then the trees and by clicking on them, their associated attributes should pop. At a high level the trees simply aggregate to look like a red circle. There is also a feature in the upper left, ( A little Blue X with an arrow attached) that lets you put an address or named location in to the search to zoom in to a specific site quickly. My favorite feature of the dataset is when you click on a tree, the attribute box pops up and there is a link to that tree in Google maps... then you can look at that tree using street view!

Thanks again for all the links.  Keep it Open!

Travis Kennedy

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?
