Re: What should I do when receiving a Crystal Reports download error during installation?

The recommended approach is to download the files from our support site and install them prior to running the installation. When installing i-Tree on a lot of computers for the first time, this may be a preferable alternative than having to wait for each computer to download them. Despite the fact t...

Re: Allometric equations

Giacomo, Given a bunch of stems, you can estimate the combined DBH by performing the following steps: 1. Take several measurements of the total width of all the stems from various sides. 2. Average the measurements from #1 to obtain the Average Width. 3. Compute the combined DBH using DBH = Sqrt[(1 ...

Jerry, Technically speaking it's not that the old values were wrong, its that they were inconsistent with the values shown on other reports. The purpose of stratification, or zones, is to increase the accuracy of population estimates by dividing the population into additional sub-categories. One rea...

Jerry, the estimations in Streets are not based upon the number of linear miles. The basic calculation is as follows: Est # of Trees in Zone = # of Trees Sampled in Zone / # of Segments Sampled in Zone * Total # of Segments in Zone In versions prior to Streets 5.1.0 the total number of trees in the ...

This is a somewhat problematic issue. i-Tree currently associates each tree with it's corresponding species via the species code. Because of this, species codes can not be easily changed. i-Tree v6 will alleviate this issue by assigning a unique identifier to each species/subgenus/genus/family/order...

What is this calculation? Asking because it had been suggested to us to use QMD to calculate a dbh for tree having more than six stems in i-eco...but that gives you an inaccurate (too small) number (dividing the sum of the squares by the total number of stems before taking the square root)...this m...

I have found the following procedure to work for me in the field: 1) define a clump as more than one stem originating from the same root system, where the stems are below the threshhold diameter (e.g., 2") being used for the project, and then 2) count or estimate the number of stems, estimate the a...

As Al stated, the error was indeed a result of the Spanish N in the word espana. As it turns out, any non-ASCII character will cause this issue. The ASCII character set is comprised of 128 characters. This basic set is then extended by an additional 128 characters from your currently selected ANSI c...

Since you did not specify the i-Tree application for which this error occurs it's difficult for us to provide support for this issue. Given the error message, I can only assume this message occurred while attempting to run i-Tree Streets. If the issue is with i-Tree Streets, simply navigate to the i...

If you're only interested in canopy cover, then I'd suggest taking a look at i-Tree Canopy. It doesn't use lidar data, but does provide a very efficient way to estimate canopy cover for an area. A simple i-Tree Canopy survey can be completed in a matter of hours which is practically nothing compared...
