I have to compare some bathy data from two different surveys (two different years)
The old data have in the table of attributes : "bathy grid=0.3" and "Major" and "minor" contour.
That is why we have asked to the Client to produce a shapefile which will have consistency with this.
The shapefile he has produced following the new survey doesn't have these info in the table of attribute.
How can I see if it is consistent anyway?
I want to make sure the data are consistent before I go ahead with the interpolation.
