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?
Thanks,
Drew
