Field <strong>Maps</strong><br />

those to the left are below the mean, those to the right are above the<br />

mean. If you have a normal dispersion of yield data in your field, 97% of<br />

all the yield points should fall ± 3 standard deviations from the mean.<br />

View a normalized harvest point map:<br />

1. Click Layers .<br />

2. Check View for a yield or moisture point layer.<br />

• The layer must be highlighted.<br />

3. Click Legend .<br />

4. In Data, select Normalized.<br />

5. In Legend, select a normalized legend.<br />

• Click Edit to create or edit a normalized legend.<br />

Example of normalized map data (using percentages):<br />

If you rotated your field between corn and beans, a normalized map would<br />

produce the following values for the two maps:<br />

YIELD VALUE: NORMALIZED VALUE: (%)<br />

Corn<br />

Average 135 bu/acre (average) 100 - (100%)<br />

Lowest yield 117 bu/acre 86.7 - (14% below average)<br />

Highest yield 156 bu/acre 115.6 - (15% above average)<br />

Soybeans<br />

Average 55 bu/acre (average) 100 - (100%)<br />

Lowest yield 48 bu/acre 87.3 - (13% below average)<br />

Highest yield 63 bu/acre 114.5 - (16% above average)<br />

Contour Legends: Solid or Outlined<br />

Contour maps are a reflection of a point map and cannot be edited All contour<br />

maps can be viewed and printed as solid or outlined. Solid contour maps are<br />

colored maps with solid areas of color; outlined contour maps are transparent<br />

layers of black lines that outline the edges of the solid contours. Outlined<br />

contour maps are used as overlays on top of solid layers.
