What do the colors on the contour map of Krafla (818m) mean?

The contour map uses a hypsometric color scale where green represents lower elevations, yellow and orange indicate mid-range altitudes, and white marks the highest zones near the summit. Thicker contour lines (index contours) are drawn at wider intervals to help you quickly estimate elevation.

What is the contour interval for Krafla (818m)?

The contour map of Krafla (818m) uses a 25m contour interval. This means each line represents a 25m change in elevation. Closely spaced contours indicate steeper terrain, while widely spaced contours show gentler slopes.

What does the elevation profile of Krafla (818m) show?
