Configure Tree Management—ArcGIS Solutions

Tree Management can be used to inventory publicly owned trees, streamline inspection and maintenance activities, understand conditions, and inform the public.

In this topic, you'll learn how to configure the Tree Management solution to meet specific needs in your organization.

Manage species roster

The Tree Management solution helps you build an inventory of publicly owned trees. Many organizations maintain a roster of approved tree species defined by common name, family, genus, species, and cultivar. The solution can be used to manage a species roster which can streamline data collection and improve data quality. First, the Species Roster CSV can be used to populate the Species Roster table in the Trees hosted feature layer. The Species Roster Notebook can then be used to update the domain and contingent values on the Trees layer to define the valid taxonomical values that can be recorded for a tree.

For example, in the table below, an American Elm tree is defined by its common name, family, genus, species and two specific cultivars, Princeton and Valley Forge. In this example an American Elm tree can be collected with a Princeton, Valley Forge cultivar or without a cultivar. Organizations can choose to define a tree's taxonomy in the Species Roster table to their desired level of detail. For example, if an organization does not define their species roster by cultivar, the cultivar field can be left blank.


commonname	family	genus	species	cultivar
American Elm	Ulmaceae	Ulmus	Americana
American Elm	Ulmaceae	Ulmus	Americana	Princeton
American Elm	Ulmaceae	Ulmus	Americana	Valley Forge

Load species roster

To begin managing a species roster, you will first load the roster into the Species Roster table using the Species Roster CSV.

Sign in to your ArcGIS organization and browse to the Species Roster CSV item.
From the item page, click Download.
Open the Species Roster CSV and add or remove rows to defined the valid tree species for your community.
Save and close the file.
In your ArcGIS organization, browse to the Trees feature layer.
From the item page, click Update Data.
Follow the steps in the Update layer wizard to load your CSV in to Species Roster table.
The Species Roster table is updated with the information from the Species Roster CSV file. Next you will run the Species Roster Notebook to update domain and contingent values according to Species Roster table.

Tip:

For more information about uploading data, see Manage hosted feature layers—Append data to layers.

Update domain and contingent values

After defining your organization's species roster in the Species Roster table, you will run the Species Roster Notebook to update domain and contingent values.

Note:

You must be assigned a role of Administrator or custom role which includes the privilege to Create and edit notebooks in order to run an ArcGIS Notebooks and complete the following steps.

Verify that you are signed in to your ArcGIS organization and browse to the Species Roster Notebook item.
Open the item page and click Open Notebook.
Click Cell then Run All.
As the notebook runs, messages will be printed beneath the cell to indicate the progress. When finished, a message will state that contingent values have been successfully updated. If the Species Roster table is empty, the message will state that contingent values have been removed from the Trees hosted feature layer.

The species roster can be maintained using the Species Roster page of the Tree Management Center. See the maintain species roster topic.

Note:

Some organizations may choose to not manage a species roster or use contingent values. The common name, family, genus, species, and cultivar domain values can also be updated manually. See the edit a list of values topic.

Modify inspection and maintenance types

The Tree Management solution helps you assess tree conditions and record maintenance activities. Inspection and maintenance types are defined on the Trees feature layer and appear in the Tree Field Map when field staff are recording their work.

The Tree Management solution includes types of inspection and maintenance. In some cases, you may want to modify inspection and maintenance types to meet your organization’s needs.

Publish a 3D tree layer

The 3D Tree Notebook can be used by mapping technicians to create and update a scene layer used to visualize trees in 3D. The Tree Management solution uses an ArcGIS CityEngine rule package (*.rpk) to visualize the trees and planting areas in 3D.

The Trees rule package uses the following fields to display a 3D symbol for trees. If a field value is blank, the default value will be used. Only planting spaces that are 'Planted' or 'Stump' will display a 3D symbol.


Field	Description	Default
Planting space status	The status of the planting space	Planted
Genus	Tree genus	Quercus
Species	Tree specieis
Height	Height of the tree	65
Height Units	Unit of measure of tree height	Feet

The Planting Areas rule package uses the following fields to display a 3D symbol for planting areas. If a field value is blank, the default value will be used. Only habitats that are 'Tree Stand' will display a 3D symbol.


Field	Description	Default
Habitat	The type of vegetation within the planting area	Other
Plant Count	The number of trees to randomly display within the planting area	50

Create tree and planting area scene layers

The 3D Tree Notebook can be used to create and update a scene layer used to visualize trees in 3D. The first time the notebook runs, it publishes new scene layers and updates the Tree Viewer (3D) web scene to point to the new scene layers. These scene layers represents a static snapshot of the assets stored in the Trees feature layer. As new trees and planting areas are added, updated, or removed from the Trees feature layer, you will need to re-run the notebook to refresh the scene layer.

Subsequent runs of the notebook will publish a temporary scene layer using the latest features in the Trees feature layer, update the source of the original scene layer to point to the new scene layer, and clean up the temporary scene layer.

Note:

You must be assigned a role of Administrator or custom role which includes the privilege to Create and edit notebooks in order to run an ArcGIS Notebooks and complete the following steps.

To create or update the tree and planting areas scene layers, complete the following steps:

Verify that you are signed in to your ArcGIS organization and browse to the 3D Tree Notebook item.
Open the item page and click Open Notebook.
Click Cell then Run All.
As the notebook runs, messages will be printed beneath the cell to indicate the progress. When finished, a message will state that the scene layer update is complete.
Exit the notebook and open the Tree Viewer app to view the 3D trees.
Note:
When you re-run the notebook and update the scene layer, you may need to clear your browser cache or open the browser in incognito or private mode to see the updated trees.

Schedule automatic updates

The notebook can be scheduled to run at a regular interval to update the scene layer to reflect the latest tree inventory defined in the Trees feature layer.

To schedule automatic updates, complete the following steps:

Verify that you are signed in to your ArcGIS organization and browse to the 3D Tree Notebook item.
Open the item page and click Open Notebook.
Click Tasks.
Click Create Task.
For Title, type 3D Tree Task and click Next.
Set the schedule for your notebook to run.
Click Create Task to finish scheduling the notebook.

Update the trees rule package

The Tree Management solution uses an ArcGIS CityEngine rule package (*.rpk) to visualize trees in 3D. The rule package is configured with a set of 3D models which are used to display some of the most common street tree genera.

If there is a matching model for the trees genus and species the model is used to display the tree. If there is a match for the genus but not the species the first matching tree genus model is used. If there is no matching model the default tree model for Quercus Rubra (Northern Red Oak) will be used. You can update the rule package to add additional tree models for common tree species in your community.

To update the tree rule package, complete the following steps:

Verify that you are signed in to your ArcGIS organization and browse to the Tree Data Management desktop application template.
From the item page, click Download and then unzip the folder.
From the unzipped folder, browse to the Trees\assets\Vegetation\Realistic folder.
Place the additional tree models in this folder.
Note:
The model must be a GL Transmission Format Binary file (.glb) and name of the model should follow the pattern of GenusSpecies.glb.
From the unzipped folder, browse to the Trees\assets\Vegetation\Metadata folder and open the vegetation_metadata.csv file.
Add additional rows for each additional tree model you placed in the Trees\assets\Vegetation\Realistic folder and save the file.
Note:
Ensure the genus and species fields match the name of the model you placed in the tree model folder. Provide a unique common name for each tree and height values (average, min, and max) specified in meters.
Start ArcGIS CityEngine.
From the File menu, click Import/Link Project Folder into Workspace.
From the unzipped folder, browse to the Trees folder and click OK.
Click Finish.
In the Navigator window, expand the Trees/rules folder.
Right-click the Trees.cga rule and select Share As.
Select Save package to file, browse to the Trees folder, name the output Trees.rpk, and click Save.
Check Include CGA source code.
Click Share.
When the packaging finishes, browse to the Trees Rule Package item in your ArcGIS organization.
From the item page, click Update.
Click Choose File, browse to the Trees.rpk file, and click Open.
Click Update Item.
Note:
The next time the 3D Tree Notebook is run it will use the updated rule package to generate the Trees scene layer.
