i-Tree Eco Resources
i-Tree Database Resources
i-Tree Database provides a central submission site for new location-specific data coming into i-Tree from around the world. Submitted data will be vetted and officially added to i-Tree Eco and potentially other tools in the future. Users in these new locations will be able to update their software and run an analysis with new locations and species without requiring manual processing by the US Forest Service. Below are some files that are used in the data submission process with i-Tree Database.
- Eco v6.0 International Guide - for International Projects outside of the U.S, Australia, Canada and the U.K.
- Precipitation Data templates - A link to the precipitation data templates used for submitting hourly precipitation data in i-Tree Database.
- Air Pollution Data templates - A link to the air pollution data templates used for submitting local pollution data in i-Tree Database.
i-Tree Streets & STRATUM Resources
Documents for STRATUM also pertain to i-Tree Streets as Streets is an adaptation of the original Street Tree Resource Assessment Tool for Urban Forest Managers (STRATUM) application.
i-Tree Canopy Resources
- Canopy Technical Notes - A document describing basic procedures, limitations and calculations for i-Tree Canopy.
- Canopy boundary shapefile guide - A guide providing basic procedures for downloading and preparing a shapefile boundary with ArcGIS for use in i-Tree Canopy. Procedures should also apply for most GIS packages and free versions such as QGIS.
- Canopy air pollutant removal and monetary value model descriptions - This document describes the methods and limitations used in determining default value multipliers for air pollutant removal rates and monetary values for a unit tree cover. The derived multipliers are incorporated in the i-Tree Canopy model to estimate air pollutant removal and values for locations in the conterminous United States.
- Carbon Storage and Sequestration by Trees in Urban and Community Areas of the United States - This document is used to determine default values for carbon dioxide storage rates (g/m²) and carbon dioxide sequestration rates (g/m²/yr.) used by the i-Tree Canopy application.
- Tree and Impervious Cover Change in U.S. cities - Nowak & Greenfield - A 2012 journal article using photointerpretation (PI) methodology to compare tree & impervious cover change in U.S. cities.
- Photo interpretation comparison with NLCD imagery - A 2010 journal article comparing the accuracy of NLCD imagery using photointerpretation (PI). The PI methods are the foundation for the i-Tree Canopy application. Article also describes methods for integrating quality assurance in a survey.
Predefined i-Tree Canopy cover classes
The following (3) Canopy cover class examples can be input in to an i-Tree Canopy project. The first (2) examples were designed for use in conjunction with i-Tree Hydro analyses. The third example was used by the Wisconsin DNR for their multi-community Canopy survey to include "potential" tree canopy. The cover class files themselves can be downloaded, saved to your computer and uploaded within i-Tree Canopy as you configure your survey.
- This example has (8) cover classes and differentiates between impervious covers:
- This example has (6) cover classes and lumps impervious cover in one class:
- This example has (6) cover classes and includes a "possible tree canopy" cover type:
i-Tree Design Resources
- i-Tree Design Methods - An updated summary describing methods and processes used in the i-Tree Design v6 application. Updated September 2014.
