Central Kansas | Could you export the field with no data from a year with data to an ASCI file and edit the data for the missing year and reassign data for mising year. If you use the a average yield it should not affect the three year average data. If you are comfortable that the good data you have is representative of the field you might use that data and just change the year. Then reimport the field into the missing year so that you maintain three year averages.
I think I could do this in SMS but am unsure about Map Calc. | |
