This GIS dataset represents 5-meter contour lines, which depict elevation variations across the terrain based on the 2018 DEM points. Contours are a widely employed technique for representing the elevation or altitude of the Earth's surface. These contour lines offer valuable insights into the overall terrain. The contour interval, which is the vertical gap between neighboring contour lines, can be used to gauge the elevation changes relative to the map's scale, providing a measure of the terrain's steepness or hilly nature.<\/SPAN>This layer is a subset of the 1m contour lines layer.<\/SPAN><\/P>
