Square, checkerboard or quilt pattern usually indicate agriculture (different greens equal different types of crops)

Rivers, streams, and bayous appear as wavy lines (irregular, wavy=nature). If image has color, water is usually but not always colored blue or dark grey.

Light grey = populations, development, urbanization (straight lines = infrastructure, man made)

Brown, light tan is usually an indication of soil exposure (as in clearing for development, planting or natural settings such as deserts and beaches)

Darker shades typically indicate thicker vegetation or deeper water

Lighter shades typically indicate sparse vegetation or more shallow water (may also show soil erosion in water)
