Click to edit Master title style Click to edit Master title style Color Survey Results

• For each of the three terrain types (urban, rural and mixed)

Sanborn came up with a baseline of settings for color and brightness.

• Survey contained three additional samples for brightness

and color to compare against the baseline.

• Brightness: Preference was for higher contrast/brightness
• ver the Sanborn Baseline
• Color: Preference for the Sanborn Baseline
• Separate survey to Area 3 partners indicates that Area 3

does not need to be color-balanced with spring imagery.

• Who: A volunteer subset of DRAPP partners

• Denver /Aurora- 9 tiles Area 1a
• Deer Trail- 9 tiles Area 2
