indicated with different kind of contour numbers , which are showed in brown curved lines
Index contours
Contour lines refer to the elevation of a line as it runs through a mapped area. For instance a 1,000ft. contour line might meander through an open field or wrap completely around a hill. On any map the "Contour Interval" is indicated somewhere as 25FT or 50ft. or 100ft. meaning that it will be this distance vertically between lines of the same altitude. In flat lands it may be a long distance between contour lines but on a steep slope they might be crowded close together.
it is a contour line of elevation Control index contour, or just index contour

the contour interval is the difference in elevation between contour lines that are next to each other
A thicker line that has numbers written on it showing the rising or decreasing elevation on a topographic map By Ash Every fifth contour line on a topographic map, usually thicker, used to label elevation.
It makes it easier to count the number of contour lines.
The numbers of contour lines indicate altitude or elevation along that line.
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
