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...

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...

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...

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...

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 ...

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 ...

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...

All weather data come from the network of weather stations available from the National Climate Data Center (http://www.ncdc.noaa.gov/). 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...

If you have a shapefile of your desired boundary but it is in the wrong coordinate system or projection, and you have have access to ArcGIS follow this forum post (http://forums.itreetools.org/viewtopic.php?t=644&highlight=canopy) to reproject your file. If you have a shapefile of your desired b...

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 ...

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. This ...
