Usually Alfalfa, Grass Pasture, and some grains had <br />CAS and GIS data so a weighted average of the CAS was multiplied by the GIS <br />acreage to obtain the total county acreage for a given year. If the average cropped <br />acreage ever exceeded the GIS amount then the GIS acres were used as a default. <br /> <br />Calculation: <br />. u _ .- CASYEAR <br />Co nty_Acres- GIS_Acres CASAVERAGE <br /> <br />Example Calculation: <br />Alfalfa acres 1996 <br />27,017 acres * 34,800 acres /36,125 acres = 26,218 acres <br /> <br />See the following two tables for the entire Delta County Colorado crop acreage <br />calculation. <br /> <br />2 <br />
