Define Species & Species Value Questions

Hi Mark, You are correct that the climate zone selected determines the species codes available. Here is the list of all species codes by climate zone ( http://www.itreetools.org/streets/resources/Streets%20Species%20Codes.xls ). Regarding the limited number of species in i-Tree Streets. Streets is b...

Creating circular areas for use in Canopy

This is not currently possible within i-Tree canopy. However, depending on what resources you have available, it should be relatively simple in GIS. In Esri's ArcGIS or the free QGIS you could create points and then just buffer those points with a 2 mile buffer. A buffer around a point should be cir...

What Eco climate regions for US, Canada and Australia?

The climate regions are used in Eco to calculate energy benefits of trees in proximity to buildings. In the US individual counties are assigned to climate regions. However, since specific data related to these benefits was not collected for Australia or Canada, the benefits for those countries are c...

Canopy Study Area Size Limitations

The study area size actually does not have much of an effect on how canopy functions. The only real limitation that I see is that in a really small study area (like a single residence or less than a couple acres) the resolution of the images used may become an issue. The main concern is that your es...

no individual tree values from Streets

Unfortunately there is no way to generate individual tree benefits using i-Tree Streets. This is a limitation imposed by the way Streets actually calculates it benefits values. Instead of calculating benefit values for each tree then summing those up it creates diameter distributions and calculates ...

generating random sample points for use outside of Canopy

One of the goals of i-Tree Canopy is to create an easy method to assess canopy coverage without the use of GIS software which can be expensive and generally requires specialized training. However, I can see why you may want to be able to use imagery outside of that Canopy currently uses. Here are a ...

Creating mdb files for Streets with MS Access 2010 or 2013

MS Access 2010 and 2007 created .accdb files by default and do not offer the ability to create .mdb files once a database is created. To avoid this limitation it is possible to make MS access create a .mdb file using the following steps. Launching Access displays the following screen. http://i216.ph...

For users in the US, Canada, Australia and the United Kingodm users select the specific location of the weather station to use during the project setup within i-Tre...

This error appears to only occur with users using Internet Explorer 8. The easiest ways to avoid this error when loading or running an i-Tree canopy project is to: 1) Upgrade to Internet Explorer 9 or 2) Use a different browser such as Google Chrome or Mozilla Firefox or 3) If you must use Internet ...

Can I use my own images in Vue?

i-Tree Vue has no method to analyze or input external images or spatial data sets. The algorithms in i-Tree Vue make use of the specific data contained in the National Land Cover Database (NLCD), including land cover type classification, percent impervious cover, and percent tree canopy cover.
