Hi!
Here there are two problems:
1. How to import the sampling design
First the "Tools -> import -> update records using CSV" feature you are trying to use is NOT used for importing the sampling design.
So the menu item saying "Update current records using CSV" means that the information on the database that has already been collected can be updated using a CSV file. This is not used for importing a sampling design. Say that you would like to update the value of the ecological region that the plots in a region belong to. You would do that here.
See how here : link.
You will need to import your sampling design by clicking on "Tools->Properties" and then use the "Browse..." button to open the CSV that contains the sampling design.
\Now to the second problem :
2. How to create your own sampling design
Ok, this is a bit more difficult.
In Collect Earth the minimum requirement for a sampling design file (the CSV that contains the plot locations) is a file with headers like so:
plot_id,latitude,longitude
It is important the order of the columns, so id,latitude,longitude should be in that order!
But this is the "starting point". So if in your Collect Earth survey you have included attributes like elevation, slope and aspect that are marked as coming "From CSV" in the Collect Survey designer, these have to be included on the sampling design.
So you if you have elevation, slope and aspect as coming from the CSV you need to add them to the CSV with the same order they were defined on the survey. So you get a CSV/CED with headers
plot_id,latitude,longitude,elevation,slope,aspect
If you want to know the format that is expected for your survey the easiest thing to do is to check the structure of the data on the file called test_plots.ced inside the CEP file create by the Collect Survey Designer. This file is generated dynamically for the survey so it contains the exact format expected for the survey.
