Do I have to repeat this all over again ???
I’m doing extracting zone value from a section to certain position defined before, so called station number in map info. There are 7 section, elongated north to south one of them, and the remaining is elongated west to east. I’m doing this so I can see the distribution of zone value laterally. I was made it only in surface 0, 25, 50, 75, 100. We found a discontinuity in surface 50. The distribution seems go wrong, because the gridding of 25 and 75 are continued. I don’t know, so I cut it more detail, in every 10 meter. When I trace it in baseline (NS), i found my mistake assign false number. It assigned 1 instead of 4. Gee, since I have only 4 zone value, this is really a fatal mistake!
