Re: Sample plot size distribution per stratum

Thanks for your question. The area of the stratum does not impact the appropriate number of plots. The number of plots will directly impact the sampling error of your project and if you want to minimize that sampling error you would need to place more plots in strata that have high variability. This...

Re: Plot based land cover class estimation

Thank you for your questions. 1. The land cover classes of a given plot should be determined in terms of percentage, according to the users guideline. However, I couldn't see any mechanism how to estimate the land cover classes at plot level during the field survey. Does it mean estimation based on ...

Re: Adding Weather Stations to add precipitation data

Unfortunately, we cannot accept new weather station data at this time. The weather station data has very strict formatting requirements and requires information about hourly wind speed, mixing heights, and cloud cover that are not readily available from most weather stations. For more information ab...

Re: Eco v6 crashed or stopped working

There is an issue with a recent automatic Microsoft update that is causing this problem. Essentially, there is an entry in the computer's registry for the 32-bit version of the MS Database Engine however the update removes or disallows the 32-bit version. This issue will be resolved in the next rele...

Re: Social cost of carbon

UPDATE: 7-30-20 The current cost of carbon used in i-Tree Canopy and i-Tree Eco is $170.55/ton of C and this has been updated with the 2019 PPI which was down 1.1% from 2018. We consider this to be in 2020 dollars as it is using the latest available PPI. User's can check on the latest default carbon...

Re: Significance of Crown Measurements

Hi Charlotte, This can be difficult to answer and varies depending on your tree population. If your trees are similar to the ones used to create the models that estimate crown parameters based on dbh then there will be little impact on average. However, for any single tree the differences may be lar...

Re: Trouble Uploading Data for Report

Hi Charlotte,
Yes, please email your spreadsheet and your packed project to info@itreetools.org. You can create a packed project from the "file" menu in i-Tree Eco then send along the .zip folder that is created.
Thanks,
Jason

Re: Trouble Uploading Data for Report

Hi Charlotte, The limitations on the "crown: base height" are that it must be greater than 0 and less than the "crown: top height". Additionally, if you have selected to collect "crown size" parameters you must supply valid values for "top height", "base height", "width" (in both directions), and "p...

Re: Trouble with Crown: % Missing

Hi Charlotte, Thanks for your question. The field guide covers the acceptable values for each variable https://www.itreetools.org/documents/274/EcoV6.FieldManual.2020.06.10.pdf . In this case it can be 0 or 100 or the midpoints of 5% classes rounded up. So the acceptable values are 0, 3, 8, 13, 18,....

Re: Update issues

Thanks for the question. I haven't seen that exact error message before but it looks like some temporary files needed for the updated got corrupted or sent to a different folder. As a solution I would suggest uninstalling your current version of Eco and downloading the latest installer. You can get ...

Re: Adding current pollution and precipitation data

Hi Lulia, Thank you for your question. This is actually very timely. As of earlier this week we are now able to accept precipitation and pollution data through 2018. When you download the templates from i-Tree Database you should see that the precipitation and pollution templates both make this poss...

Re: Hello forum and question.

Hi and thanks for the question. This is a little tough to answer because I am not sure which tool you are using and what data you are trying to import. For i-Tree Canopy you can load your own boundary files from .shp. For i-Tree Eco you can import inventory data from many spreadsheet formats includi...

Thanks for your question. This was a bug in the software that has since been fixed. In order to ensure that you are running the fixed version of mobile collection form you will have to clear the cache on the browser you are using before reopening the data collection link. Before you do that you will...

Re: How to export to CSV with scientific name first in Species column?

Hi Mary, Unfortunately I don't think they will be making that change. Our most limiting resource is developer time. Even small changes like this tend to have a cascading effect that requires editing every report table that includes species names. Our management team is very cautious about limiting o...
