TREE COLLECTION APP PRESENTATION OVERVIEW


THE NEED

Data Need

• Previous Inventory efforts had known spatial quality issues & were known to be incomplete snapshots in time

• Hansen 8 is the System of Record for Tree Assets attributes in SDOT – Not GIS

• GIS is the Spatial System of Record

• Editing the Inventory was complicated and time consuming. Attributes had to be entered into multiple screens in Hansen then users would have to place a point in GIS using GIS editing tools on a versioned feature class


THE NEED

Management Need

• SDOT Urban Forestry Management wanted to proactively manage work and report performance metrics using the Tree Inventory

• New management approach• 9-year Street Tree Management Plan• 2016 – 2024 - Move Seattle Levy• 27 management units• City council districts divided along U.S. Census tracts• 3 units per year


THE NEED

• Use ArcGIS Collector App to update street tree inventory with handheld devices

• Hire additional inventory support staff

• Inventory all street trees in Seattle


THE NEED

• Scheduled pruning and maintenance

• Emergency Response

• Hazardous Tree Removal

• Establish recently planted trees


THE NEED

• Plant at least two trees for every one removed

• Leverage existing gaps within SDOT tree “corridors”

• Use iTree analysis of inventory to make better decisions

https://www.itreetools.org/


THE NEED

• Conduct Racial Equity Toolkit Analysis to optimize benefits and minimize harm

• Community Survey

• Fact Sheets

• Multimedia Awareness Campaign

• Partnership with Department of Neighborhoods

https://www.seattle.gov/rsji/resources


WHAT IT IS

• 1 Configured ArcGIS Online web map with one editable layer used in Collector for ArcGIS for data collection

• 1 Configured ArcGIS Online web map with one editable layer for content QA/QC by SDOT Urban Forestry Subject Matter Expert

• Custom developed code to move data from SDE to Hansen• Initially done with Python scripts that operated

overnight to move data through a series of feature classes based on flagged fields

• Currently through triggers to move data into QA/QC real-time and into Hansen real-time then scripts to push data into Production GIS datasets nightly

HOW IT WORKS

FIELD

GIS Processes to incorporate data

identified as new or changed into QA/QC

dataset and automated

verification that all mandatory fields are

populated and all data types are

correct

Processes to push data QA/QC-accepted data into

Hansen and GIS.

Tree Data Collected in the Field for attributes defined by data dictionary

Users will be able to:- Add new trees- Remove trees from inventory- Change attribute values as defined by the data dictionary- Move the location of trees

Overnight Process to update

SDOT.V_TREES– a GIS Feature Class

which shows all non-expired trees and

select Hansen attribute

Copy SDOT.V_Trees including attributes to SDOT.Trees_Field

– a versioned/editable Feature

Service. This will be the dataset that new

and changed data collected in the field

will be written.

QA/QC Process -Urban Forestry Subject

Matter Expert to review data for content that automated processes can not capture

GIS stores Locations

QA/QC


HOW IT WORKS

Exercise – Reforestation of Lake Union

1.) Add a tree with the following parameters:• Edit Type – ADD• Street Segment – 10533• Scientific Name – Choose Any from List• Address – 700 5th Ave• Diameter – Enter any positive number• Planted Date – Today• Funding Source – Choose Any from List• Current Status – Choose Any from List• Last Verified Date – Today• Ownership – Choose Any from List• Tree Pit Treatment – Choose Any from List• Remaining fields enter as wish


HOW IT WORKS


2.) Either Change Attributes, Move a Tree, Change Attribute & Move a Tree or Remove a Tree

• Change the Tree Species

• Move a Tree from elsewhere on the map into Lake Union

• Change a Tree Species and Move the Tree into Lake Union

• Remove a Tree around the perimeter of Lake Union


HOW IT WORKS


3.) SME QA/QC by SDOT Urban Forestry Arborist

FUTURE

• Complete inventory for entire City

• Work with Parks who maintains a separate tree inventory• Is there a good way to ensure consistency between the inventories

• Collaborate with Office of Sustainability and Department on Neighborhoods efforts around Seattle Trees

• Consider the Tree Inventory in Storm Response preparedness work

• Others to consider?
