![]() In this example, Contour Interval is specified as 100.ĭefine the space between two contour lines using either the static (by specifying the Contour Interval field) or dynamic (by specifying the Number of Contours field) value. Contour lines connect points that share the same elevation: Where theyre close together (they never intersect). Specify either the Number Of Contours or Contour Interval field to determine the space between two contour lines. Contour lines indicate the steepness of terrain.If Z Base is specified as 1,434, the 100 increment starts from this value, that is, 1,534, 1,634, 1,734, and so forth. For a study area with a minimum elevation of 1,434 meters and a contour interval of 100, maintaining the default Z Base value creates increments of 100s, starting from the next nearest hundredth, that is, 1,500, 1,600, 1,700, and so forth. The default value of Z Base is 0, which represents the mean sea level. In this example, it is 1,434 meters, as this is the lowest elevation in the study area. For Z Base, specify the base contour value.For Contour Type, ensure the default Contour lines option is selected.So it is actually a line of constant height above the mean sea level. For Raster, specify the desired single-band raster layer. Contour is actually an imaginary line, which joins the points or places having the same height above the mean sea level.Refer to ArcGIS Pro: Contour function - Parameters for more information on parameter settings. ![]()
