I have a Feature Collection I'm exporting as a csv. I used the reduceRegions function to get mean values of several different variables per region, and merged these into one large FeatureCollection. I simply want to chnage the column/property name for one of these. I found you could use the select function, but I have to rename one but still all the columns in as otherwise the selec function removes them from the FeatureCollection.
//var Dat = Dat.select(['mean', 'id'], ['SE_score', 'id']);
However, I'm getting this error
FeatureCollection (Error) Error in map(ID=7_PB_IleDiamant_Lagoon): Feature.select: Selected a different number of properties (1) than names (2).
I think this is because I don't actually have data for some of these variables, they're just blank, which is fine for my export, but it means it's not allowing me to change the property name from 'mean' to 'SE_score'.
Are there other methods for changing column/property names you're aware of?
