It will looks like a hemisphere or a globish shape, like a sphere of some kind.
A contour line that is bold and labeled is called an index contour line. These lines help to easily identify specific elevations on a topographic map.
Index contours are specially drawn contour lines that represent a specific round number of elevation, usually labeled with the exact value. They are useful for quickly identifying key elevation points on a topographic map.
An index contour is typically indicated on a topographic map by a bold line, often labeled with its elevation in feet or meters. These lines are usually spaced at regular intervals, such as every 100 or 500 feet, and help to provide a clear reference for understanding the terrain's elevation changes. In addition to the index contours, intermediate contours may be shown as lighter, thinner lines between the index contours.
An Index Contour
A contour line on a topographic map is typically labeled with the elevation in round units. This helps to indicate the elevation of the land and the change in elevation across the map.
The heaviest contour lines on a topographic map indicate the highest elevation on the map. These lines represent the peaks of mountains, hills, or other elevated land features.
A contour interval is the vertical distance between contour lines on a topographic map, representing the change in elevation. An index contour is a heavier contour line that is labeled with the elevation value, to help users quickly identify key elevations on the map.
An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.
Index contour lines are thicker and usually have their elevation labeled. They help users quickly identify key elevations on a topographic map. In contrast, regular contour lines show the shape and elevation of the land but do not have specific labels.
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.
its called an index or index conotour line and is every fitth line on a topographic map.
A contour line that is bold and labeled is called an index contour line. These lines help to easily identify specific elevations on a topographic map.
it is a contour line of elevation Control index contour, or just index contour
Index contours on a topographic map can be identified by looking for thicker contour lines compared to the surrounding lines. They are typically labeled with their elevation value. Index contours are used to provide a quick reference to the elevation changes on the map.
It would be the difference between the two darker lines, or index lines, and then divide the space in between with your difference.
Index contours are specially drawn contour lines that represent a specific round number of elevation, usually labeled with the exact value. They are useful for quickly identifying key elevation points on a topographic map.
