Terms in this set (6)
- How is height shown on a map? There are 3 main methods of showing height on maps that are spot height , layer colouring and contours.
- Spot height. A point on a map with a number giving its height above sea level in metres.
- Layer colouring / layer shading.
- Triangulation pillar.
- Contours.
- Relief.
What are the 3 factors that should be considered upon planning and designing of a contour interval to be used for a topographic map?
The Contour Spacing Depends On The Following Factors:
- The Scale of The Map. The contour interval is inversely proportional to the scale of the map.
- Nature of The Ground.
- Purpose and Expansion of the survey work.
- Time available and Eligible Expenses for field and office work.
How is height shown on a topographic map?
What are contour lines? Contour lines connect a series of points of equal elevation and are used to illustrate relief on a map. They show the height of ground above mean sea level (MSL) either in metres or feet, and can be drawn at any desired interval.
What are the different methods of showing elevation or height of the land?
They can be shown on maps by contour lines, which connect points with the same elevation; by bands of color; or by numbers giving the exact elevations of particular points on the Earths surface. Maps that show elevations are called topographic maps.
What are the uses of the map showing Heights?
What are the uses of maps by showing heights
- Maps showing heights are very essential in the construction of roads and dams.
- It also helps us to understand the nature of the terrain, where the mountains are, where the valleys are etc.
- It tells us elevation (how high land is above the sea level).
How can you measure your height?
Measure from the floor to the pencil mark with a measuring tape.
- If your measuring tape is too short to measure your full height, measure as high as you can and make a pencil mark on the wall.
- Note the measurement.
- Keep measuring this until you reach the pencil mark you made using the box.
What is spot height on a map?
A spot height is an exact point on a map with an elevation recorded beside it that represents its height above a given datum. In geoscience, it can be used for showing elevations on a map, alongside contours, bench marks, etc.
Which method of showing the elevation of the land is shown in a diagram?
Answer: Contours are imaginary lines joining places having the same elevation above mean sea level. A map showing the landform of an area by contours is called a contour map. The method of showing relief features through contour is very useful and versatile.
Which is the best way to show height on a map?
There are 3 main methods of showing height on maps that are spot height , layer colouring and contours. Spot height. A point on a map with a number giving its height above sea level in metres. Layer colouring / layer shading.
How are geographic coordinates converted to two dimensional coordinates?
Map projection. To establish the position of a geographic location on a map, a map projection is used to convert geodetic coordinates to two-dimensional coordinates on a map; it projects the datum ellipsoidal coordinates and height onto a flat surface of a map.
How are UTM coordinates measured on USGS topographic maps?
The northing values are measured from zero at the equator in a northerly direction. Each zone has a central meridian that is assigned an easting value of 500,000 meters. In Zone 16, for example, the central meridian is at 87 degrees longitude west.
What are three ways to show scale on a map?
There are three ways to show scales on maps. 1. A ratio or representative fraction using ratios to measure and calculate distances 2. A word statement that states the conversion of base units and is also a description of a map distance 3. A graphic scale and sometimes a scale can be large or small
