An RF is a ratio and is shown as follows: 1:50 000. At a map scale of 1:100000, 1 kilometer on the ground is equivalent to 1 millimeter on the map. Map scales are expressed in a variety of ways (RF, verbal, graphic). scales can be compared between different maps. Correct answers: 1 question: Reading and using statement of scale, scale and scale shown by representative fraction method. 2. If the scale is a representative fraction (and looks like 1/100,000), multiply the distance of the ruler by the denominator (100,000 in this case), which denotes distance in the ruler units. 3. For example, a map where one unit (centimeter, meter, inch, kilometer, etc.) The numerical scale of a map indicates the relationship of distance measured on a map and the corresponding distance on the ground. equals 1 million cm. Two of these different kinds of scale are shown on your map. Representative fraction and scale bars from a United States Geological Survey (USGS) topographic map. The graphic scale is sometimes called the bar scale, and the representative fraction is the RF or the fractional scale. 1:50000 can be shown as 1/50000 as well. This scale is usually written as a fraction and is called the representative fraction. For example, if we say that the scale of a map is 1 cm : 1 km, it would be understood by only that person who is familiar with the metric system of measurement. All but the first options are verbal scales – choose the one that will make the most sense to your map readers. 1:50,000 means 1 unit on map represents 50,000 units on ground. Such maps are called large scale because the representative fraction is relatively large. Graphic scale remains accurate if a map is enlarged or reduced. 3.2.1 Representative fraction. ... EurLex-2. Map scale is the proportion between a distance on a map and a corresponding distance on the ground: (D m / D g). Representative fraction (RF) or natural scale 1:1,000,000 (this is the same as 1/1,000,000) The RF says that 1 of any measurement on the map equals 1 million of the same measurement on the original surface; for the example above 1 foot equals 1 million feet or 1 cm. A representative fraction, or RF, shows the relationship between one of any unit on the map and one of the same unit on the ground. The advantage of this distinction between varying scale on the super map and a constant RF is that for the former we can analyse scale variation around a value of unity. The units will be listed on the map, such as 1 inch or 1 centimeter. The verbal scaleis a simple statement of the scale such as one inch equals one mile or 1" = 1 mile.The unit on the map should be appropriate to the dimensions of the map. Verbal and RF scales do not. Representative Fraction The expression of map scale as a mathematical ratio. In representative fraction (RF), the scale on the map is expressed in the numerical fraction. For example, a scale of one inch to a furlong (1:7920) ... To avoid confusion in the use of the word 'scale' this constant scale fraction is called the representative fraction (RF) of the printed map and it is to be identified with the ratio printed on the map. RATIO or REPRESENTATIVE SCALE A ratio or representative fraction (RF) indicates how many units on the earth's surface is equal to one unit on the map. REPRESENTATIVE FRACTION (R.F.) Example sentences with "representative fraction", translation memory. The notes below highlight key points which are not explicitly stated on slides. Topic: Example of Map Scale – Representative Fraction Fall 2020 Geog 104 1 Instructions: Online instruction provides challenges in delivering lecture material.The additional explanatory text below adapts lecture slides for online viewing. Answer: For graphical scale, to know the length of the line we need to make following calculations. 2. C) A Representative Fraction Scale removes the units and shows the direct relationship between the two measurements. This RF scale means that 1 unit on the map represents 50 000 of the same units on Earth's surface. The scale represents the ratio of a distance on the map to the actual distance on the ground. This type of scale representation visually looks very similar to representative fraction (RF). Representative fraction scale (RF): Two other terms refer to the representative fraction scale - the fractional scale and the RF scale which is the scale ratio written in fractional form, 1/20,000. Its advantage is that it has universal application. ), also known as scale ratios, relate the size … method called a universal method because of its usefulness on global scale. Because an R.F. For example, scale that has a RF of 1:100 means that every one unit on the map equals one hundred of the same units on the ground. ... Representative Fraction (R.F.)
