How do you read a graphic scale?
How do you read a graphic scale?
To use the graphic scale, mark the distance between points on the edge of a sheet of paper. Then put the right hand mark on an evenly measured mark to the right of the zero SUCH THAT the left hand mark falls between the zero and the left edge of the scale.
Why isn’t 0 at the far left of the scale?
Why isn’t “0” far left of the scales? It’s not on the far left side because it wouldn’t allow us to be much more precise if it was at the far end. Being where it is, it gives us a closer approximation to the actual distance in the real world.
Why does the graphic scale have the 0 in the middle rather than on the left hand side?
Terms in this set (10) Why isn’t “0” at the far left of the scales? Easier to read fractions of miles, etc. If a map with these graphic scales is enlarged along with the scales (such as by using a photocopy machine):
How do you read and use the statement of scale graphical scale and scale shown by Representative fraction method?
Statement of a scale describes in words the distance between two places on map and same two places on ground. I is represented by fraction or in ratio which is called the representative fraction. EXAMPLE: 1/50,000 or 1: 50,000 written on map means 1cm on the map is 50,000cm on ground.
How do you read and use the statement of scale?
Statement Scale The scale of a map may be indicated in the form of a written statement. For example, if on a map a written statement appears as stating 1 cm represents 10 km, it means that on that map a distance of 1 cm is representing 10 km of the corresponding distance on the ground. 1 inch equals 16 miles.
What type of scale is the following 1 65000?
The ratio of 1/65,000 is the “smaller scale” map (having less detail). Maps also have a representative scale to help you visualize real-world distances. You can use this scale and a string or the edge of your compass to get a rough estimate about hiking distances on your map.
How do you read representative fractions?
Representative fractions are expressed in the form of 1 followed by a : (colon) and then a number, where the one is the numerator in the fraction, the colon represents the division operation, and the other number is the denominator. Thus, a scale of 1:24,000 can be expressed mathematically as 1/24,000.
What do you understand by RF 150000?
Representative Fraction (RF) – Fractional Scale – Ratio Scale: 1:50000 represents the map scale as a mathematical ratio or fraction, thus the name ratio scale or fractional scale. Here such a scale means that one unit of measurment on the map is equal to 50000 of the same unit on the ground.
How do you calculate RF scale?
Which is the representative fraction of the map scale?
Representative Fraction (RF) – Fractional Scale – Ratio Scale: 1:50000 represents the map scale as a mathematical ratio or fraction, thus the name ratio scale or fractional scale. 1:50000 can be shown as 1/50000 as well.
What does the numerator on the fractions scale mean?
Fractions scale shows, in how many pieces a piece minimized. The numerator in fractions scale is stable as 1. Denominator is variable. The minimization rate and the denominator of fraction are equal. The numerator signifies the length on map and the denominator signifies the length on terrain.
What are the advantages of the representative fraction scale?
One of the major advantages of using the R.F. (Representative Fraction) scale is that it allows you to directly compare the sizes of objects between different maps. Because the R.F. eliminates the use of specific units (such as inches, feet, miles, etc.), there are no complicated conversions needed.
What does the scale mean on a map?
In current use, there are two sorts of scale : If the rate between actual length and the length on map represented with fractional numbers; it is called fractions scale. 1:1000 or 1/10000. Fractions scale shows, in how many pieces a piece minimized.
