Stream Point Attributes

  • Latitude - The angular distance of a place north or south of the earth's equator (units: decimal degrees).

  • Longitude -The angular distance of a place east or west of the meridian at Greenwich, England (units: decimal degrees).

  • Unique identifier - Numeric site identification that begins with 0 at confluence and increases upstream towards headwaters.

  • Sinuosity - A stream’s tendency to move back and forth across a floodplain in an “s” shaped pattern over time. Term calculation is stream distance/Euclidean Distance. A value of 1 = straight and >= 1.5 is considered meandered, from point to point starting at confluence moving towards headwaters.

  • Elevation - Specific location’s height above sea level (units: feet).

  • Bankfull Width - Based on perpendicular transect of point, the distance along transect from one side of bankfull polygon to the other, (units: feet).

  • Morphological Valley Width - Based on perpendicular transect of point, the distance along transect from one side of morphological valley to the other (units: feet)

  • Constricted Valley Width - The distance along transect from one side of constricted valley to the other based on perpendicular transect of each point (units: feet).

  • Elevation Change - The difference in elevation from one point to the next moving from the confluence towards the headwaters (units: feet).
