Re: how to calculate tree benefit zone?

Thanks for your question. The i-Tree energy methods drive most of those benefits zone maps and are explained in broad strokes here, http://www.itreetools.org/streets/resources/Streets_CTG/PSW_GTR202_Northeast_CTG.pdf (see around page 5 for the energy overview) and this is one of the more specific pa...

Re: Importing/Reconciling csv with addresses geocoded in Eco 6

Unfortunately, we do not have a plot-based importer at this time. You could attempt to open the .ieco project file using MS Access, locating the appropriate table, and pasting in your full columns of location information at once. This is not a supported or tested method as it is very easy to corrupt...

Re: i-Tree eco Forecast validate

Thank you for your question. The Forecasting module within i-Tree Eco was first released in 2015 the with advent of the v6 Eco application. I don't know of anyone who has done any testing on the model accuracy. However, anyone could do their own tests using historical data or any data sets measured ...

Re: Reference for method to estimate tree count

Dead trees would be included and multi-stem trees are counted as a single tree. The reasoning with including standing dead trees is that they are still storing carbon and therefore still providing some benefit. As far as replicating the software exactly you will want to make sure you are using the e...

Re: Reference for method to estimate tree count

Thanks for the question. The basic method that i-Tree Eco uses is stratified random sampling. I am not sure what data you have so it is difficult to describe the calculations you would need to perform. Also, I am not sure of the exact details of the London sample design as it is a little atypical wi...

Re: Tracking phenology data for urban trees?

Hi thanks for your question. I am not sure which i-Tree tool you are considering using. The only one that will allow you to collect coordinate data would be the mobile data collection option of i-Tree Eco. However, i-Tree Eco is not intended to be an all purpose data collection tool. i-Tree Eco is m...

Re: Importing/Reconciling csv with addresses geocoded in Eco 6

i-Tree Eco holds data in an underlying relational database rather than .csv tables. The most straightforward method to get your coordinate data into i-Tree Eco may be to create an empty project and import your .csv, assuming that your .csv contains all of your Eco data. This approach will only work ...

Re: comparing 30yr to 50yr forecast outputs

I was able to replicate that discrepancy due to different project lengths and agree that appears to a bug rather than a rounding error. I have submitted it as an issue through our internal system and our development team will take a look at it. Adding avoided runoff to the Forecast projections is on...

Re: Differences between Ecov6 field manual and program

Thanks for your question. This is a very recent update to i-Tree Eco that has not been documented in the manual. i-Tree Eco previously only used dieback but some users are more comfortable collecting a crown condition percent. Users now have the option collecting either dieback or crown condition du...

Re: How are the benefits calculated?

Hi, I am assuming you are using i-Tree Eco. In that case, most benefits are calculated on a per tree basis. In large part the benefits in Eco depend on the leaf surface area and not the canopy cover. You could potentially extrapolate data measured on some trees to the whole city but you would be mak...

Re: Eco Tree Inventory/Adding Trees

Hello Mauricio, I can't recreate this exact issue but there may be a couple things going on. It is possible that you are trying to import your height data into the "dbh height" field. That field is used for the height at which DBH is measured and is capped at 6.0 m. Alternatively, if you are importi...

Re: iTree Eco "system error" pop-up

Hi Kim, Usually when it stops at 40% it indicates that i-Tree Eco is having trouble connecting to our server. This can happen for a number of reasons. Occasionally, our server goes down. I just tested this (3:00 pm EST 5/30/19) and was able to submit a project without issue. More often it is because...

Re: Import data from Excel to Eco v6.0 in a plot-based sample project?

Yes it is possible to export data from a plot-based sample project to a spreadsheet. In i-Tree Eco you would click on the data tab, then select the "Plots" button. With the "Plots" table open you can then click on the "CSV" button to save a spreadsheet that can be opened in MS Excel. You would then ...

Re: How does i-Tree Eco simulate leaf area fluctuation in leaf-in/ leaf-off season ?

Thanks for your question. The leaf on/off parameter is a location specific parameter. For any location a user can select in i-Tree Eco the underlying database has average leaf-on and leaf-off days. In the US these dates were estimated based on frost free days while in other countries they may be pro...

Re: I'm using I Tree Eco and when I try to submit my data for processing I get the message "FTP Upload Failed."

Hello, Sorry to hear about this issue. This can be a little hard to diagnose but my first two thoughts would be: 1. Occasionally, we will have server outages. In those cases mean i-Tree Eco on your computer can't communicate with outrFTP server. I haven't seen any recent records of outages and was j...
