How to automatically assign indicator code to plant species in Wetland & Stakeout
October 10, 2016 Leave a comment
“Have you folks thought of a way to link the plant indicator status (FAC, FACW, OBL, etc.) to the species name? That way when you pick a species from the list it automatically lists the indicator status. I was looking at your Design Report and was thinking there probably is a way to do it but is beyond my knowledge. — After two different field trips to sites in central PA I find the APP to work as advertised. I like it and as I use it I will keep you posted on my questions and observations.”
For the Indicator field, you could enter a formula to tie the displayed result to the species name.
IF SpeciesName== “Acer rubrum”
RESULT = “FAC”
Then whenever you select “Acer rubrum” in the Tree Stratum, “FAC” will be displayed as the indicator code.
To try this functionality, you could save one of your projects under a “Test Job” name, then select Design Report in the app.
Tap on the Tree Stratum form and see its name highlighted on the right side. Tap the lock button to unlock it for editing then tap the “>” button.
Tap on the “Fields” tab then tap on “Indicator”.
Tap on the Edit button then mark the check box of “Has Formula”
Now you can enter the above lines to tell the app what to do when you select Acer rubrum as the species.
To facilitate the formula entry, the Name button lists the available field names for the Tree Stratum and the Command button lets you pick the commands rather than having to key in each letter.
You could use the logic operator OR to specify a few species on the same line for the same indicator status. This method can get tedious if you have a long species list to work with. We will look into the feasibility of providing a more efficient way to achieve the desired result.
(Same user suggested to add the ability to search another table to get the indicator status for the species of interest. We are working on this enhancement.)
