Esteemed colleagues: I performed a Point Inspection on a hypsographic grid. Rather than finding a new column with elevation data for each record, I found a new column with elevation data for exactly 199 records (out of ~5000). The selection of records seems to have been random. Is there a limitation on records calculated? I admit to not yet having tested the calculation on a smaller data set, but I have performed the operation before with similarly large data sets. Is there another explanation?
