Sinsinawa Creek, IL stream gradient points — sin_gradient

A sf object containing stream gradient points for Sinsinawa Creek, IL. These points represent elevation values extracted from a LiDAR terrain surface along the flowline of the stream.

sin_gradient_sf

Format

A sf with 3521 observations and 23 variables.

OBJECTID: numeric; The ArcGIS feature class assigned unique identifier for each point in the dataset.
OBJECTID_1: numeric; The ArcGIS feature class assigned unique identifier for each point in the dataset.
ReachName: character; The name of the reach.
POINT_X: numeric; The longitude or easting of the point. Coordinate system units can be determined by checking the st_crs(sin_gradient_sf).
POINT_Y: numeric; The latitude or northing of the point. Coordinate system units can be determined by checking the st_crs(sin_gradient_sf).
POINT_M: numeric; The route distance of this cross section from the upstream end of the reach. Coordinate system units can be determined by checking the st_crs(sin_gradient_sf).
Z: numeric; The elevation of the point. By convention, the vertical units used in this project are NADV88 feet.
Z_smooth: numeric; The smoothed elevation of the point. By convention, the vertical unites used in this project are NAVD88 feet.
upstream_x: numeric; The x-coordinate value (longitude) of the next upstream point in the moving window.
upstream_y: numeric; The y-coordinate value (latitude) of the next upstream point in the moving window.
downstream_x: numeric; The x-coordinate value (longitude) of the next downsteam point in the moving window.
downstream_y: numeric; The y-coordinate value (latitude) of the next downsteam point in the moving window.
upstream_m: numeric; The m-coordinate value (route position) of the next upstream point in the moving window.
downstream_m: numeric; The m-coordinate value (route position) of the next downstream point in the moving window.
rise: numeric; The elevation difference between the downstream and upstream point in the moving window, units are in feet.
run: numeric; The longitudinal distance along the stream network between the downstream and upstream point in the moving window, units are in feet.
stream_length: numeric; The longitudinal distance along the stream network between the downstream and upstream point in the moving window, units are in feet.
valley_length: numeric; The longitudinal distance along the valleyline between the downstream and upstream stream network point in the moving window, units are in feet.
sinuosity: numeric; The sinuosity of the stream within the moving window (valley_length/stream_length).
sinuosity_gte_one: numeric;The sinuosity metric, values greater than or equal to one.
slope: numeric; The slope of the stream within the moving window (rise/run).
slope_gte_zero: numeric; The slope metric, values greater than of equal to zero.
