I am using the sf_package to work around spatial data in r. At this stage, I want to make a spatial join so that the tax lots of my area of study inherit the attributes of the floodplain on which they are located. For example, taxlots may be located in a floodplain categorized as X, VE, A, A0, or V (these are codes that relate to the intensity of the flood in each area).
To do this, I tested the sf function st_join, which will by default rely on st_intersects to determine the spatial join for each entity of my tax lots.
However, I am trying to figure out the criteria used by the function when a tax lot intersects with two different floodplain areas (as in the photo below, in which several lots intersect both with an A floodplain and an AE floodplain). Does it take the value of the area that covers the largest area of the lot? or is it a matter of which area is located upper in the dataframe?
Note that I am not interested in partitioning the intersecting lots so that I divide them according to their areas intersecting one and other floodplain zones.
