The Number of Contours parameter setting disables the Contour Interval parameter. In the dynamic mode, the approximate number of contours to be displayed is defined, and the function computes the appropriate contour interval while maintaining standardized intervals such as 1, 5, 10, and so on. The contours interval can be defined as a static value or set to be dynamic with the Number of Contours parameter, and it automatically varies based on the undulations of the terrain in the display. Use Identify to display the elevation value of the contour based on the source elevation layer, which will return the elevation of the contour, point, key features, and spot heights on the maps and images. The bold index contour has a value of two (2). The contours generated from the elevation dataset are rasters with a value of one (1). Contour labels on digital maps are often not required, and the contour layer is often used to give terrain context to underlying maps and images. The contours produced by this function are rasters and, therefore, not easily labeled. They are useful in applications such as engineering, agriculture, and water management. The creation of a contour layer as a raster product is valuable for a wide range of applications since the contours can be overlaid on a map and provide information regarding the terrain without obscuring the underlying data. Output options include contour lines, index contours, and filled contours.
Dynamic control over the contour interval is provided.Contours can be smoothed to provide a more cartographic-pleasing appearance while maintaining the accuracy of the contours.Contours are quickly and dynamically generated on very large datasets, such as the World Elevation.The following key features make this function powerful:
The contours are isolines created as rasters for visualization. The Contour function generates contour lines by joining points with the same elevation from a raster elevation dataset.
