Following on from hereβ¦
geo = GeoIO.load("os_bng_grids.gpkg"), layer=4) # Read the grid gpkg file
abdf = CSV.read("addresses.csv", DataFrame) # Read the address file
subset!(abdf, [:X_COORDINATE, :Y_COORDINATE] => ByRow((x, y) -> !ismissing(x) && !ismissing(y)))
points = Point.(zip(abdf.X_COORDINATE, abdf.Y_COORDINATE)) # Convert (x,y) to geometry
geoabdf = georef(abdf, points) # join x,y geometry back to main dataset
println(typeof(geoabdf[1, "geometry"]))
newdf = geojoin(geoabdf, geo, kind=:left, pred=((g1, g2) -> intersects(g1, g2))) # Match grids to addresses based on geometry intersection
newabdf = values(newdf)
println(describe(newabdf))
The geojoin fails and the error seems to materialise in Unitful.

In this case, the points data are of type
Meshes.Point{Meshes.πΌ {2}, CoordRefSystems.Cartesian2D{CoordRefSystems.NoDatum, Unitful.Quantity{Float64, π , Unitful.FreeUnits{(m,), π , nothing}}}}
In another example of the same approach, the points data are of type
@NamedTuple{geometry::Point{πΌ {2}, Cartesian2D{NoDatum, Quantity{Float64, π , Unitful.FreeUnits{(m,), π , nothing}}}}}
and in this case the geojoin works. I donβt know why the types are different in these cases but Iβm assuming the difference is where the error arises.
What have I done wrong?
