    The contour pattern indicates a hill with vertical western flank. Closeness of contour lines tell about the steepness; closer the contour lines higher the dip angle. Refer to the attached figure for diagram.

    sir , i think they are not close spaced, they are intersected on west side., but contour lines never cross each other.

    eduncle-logo-app

    Yes, contours don't intersect. You can consider them as closely spaced because in case of any vertical cliff you will get different heights contours overlapping on each other and the same case is also shown here.

    and sir, how to make this from contour?, bcoz in simple cases i make them but in this case i Don't get how to make features from contour

    eduncle-logo-app

    sir, can you tell me the way how to draw this

    eduncle-logo-app

    First look at the contour spacings; closely separated contours will indicate steeper slope region and widely separated contours indicate shallower slope region. After that try to visualise the same in 3D and draw the section view of the same.

    yes sir the last line you wrote. how to do that. means there are 4 line on upper side and 4 at lower and close spaced at left which became vertical. but how to resolve upper and lower lines.

    eduncle-logo-app

    If you see the lines with no spacing (overlapping) then just consider that one as vertical; you don't need to resolve the overlapping lines.

    sir , i am asking about 4 upper and 4 lower spaced lines

    only the closed space part to observe here other side is for levelling to know the contour interval and contour elevation. stiff because of closely spaced contour

    but sir lines are intersected to each other.

    eduncle-logo-app

    no they are closely spaced contours can overlap can't intersect.

    eduncle-logo-app

    they are from different elevation so how can they intersect they can overlap if the topography is very steep

    eduncle-logo-app

    ok sir.

    eduncle-logo-app

    sir its difficult to me to recognise i give best to both.

    eduncle-logo-app

    okay
