Hi,

I would like to be able to produce stats in Saiku based on whether the plot is on top of hills, the slopes, or the valley. Is there a straightforward way to produce that info and attach it to each plot?

Many thanks,

Florence

The easiest way would be to add the Digital Elevation Model information to the plots.

This is a script in GEE that will generate this information per plot: GEE Script (remember to set the ID of the Fusion table in line 16 replacing the XXXXXXXXXXX token )

Then you of course need to have these attributes in the survey (elevation, slope and aspect ) remembering to set them as coming "From CSV" in the Collect Earth properties in the Survey Designer.

Afterwards you should also have a calculated attribute to classifythe plots according to these attributes, for instance using the slope attribute or the elevation so that you get classes like Flat, slight slope, severe slope and so on.

If you already collected the information then you can still add these attributes to the survey and once you have done that import the data using the menu option "Data Import/Export->Update current records using CSV"

These posts have more info on this process : Changing Plot properties and How to add information to database?
