How do you read a scale on a topographic map?
Scale is the relationship between distance on a map and distance on the ground. It’s a ratio, like 1:24,000 — which means one inch on the map equals 24,000 inches (2,000 feet) on the ground. The larger the second number, the smaller the scale. The smaller the scale, the less detail on the map.
What does the scale 1 250000 mean on a topographic map?
Notice the scale is 1/250000 – that means 1 inch on the map is equal to 250,000 inches on the real land. ( 5 miles = 5*5280 feet = 5*5280*12 inches = 316800 inches. 316800 inches / 250000 = 1.27 inches)
What is a 1 10000 scale map?
A map scale might be given in a drawing (a graphic scale), but it usually is given as a fraction or a ratio-1/10,000 or 1:10,000. These “representative fraction” scales mean that one unit of measurement on the map 1 inch or 1 centimeter represents 10,000 of the same units on the ground.
What does a map scale of 1 20000 mean?
An example: on a map with the scale 1:20000, 3 centimeters accord to 0.6 kilometers in reality. 1 cm ⇒ 20000 cm. 3 cm ⇒ 20000 * 3 cm = 60000 cm = 600 m = 0.6 km. The scale is rounded to integers, the distance of the map to 0.1, the real distance to 0.001.
What does a scale of 1 24000 mean?
For example, a map scale indicating a ratio of 1:24,000 (in/in), means that for every 1 inch on the map, 24,000 inches have been covered on the ground. Ground distances on maps are usually given in feet or miles.
What does the scale 1 50 000 mean?
A map would also usually give its scale numerically (“1:50,000”, for instance, means that one cm on the map represents 50,000cm of real space, which is 500 meters)
What does a map scale of 1 25 000 mean?
The basics On a 1:25 000 map, such as an OS Explorer, one unit of length on the map represents 25,000 units on the ground. So 1cm on the map represents 25,000cm or 250 metres on the ground.
What does 1 500000 on a map mean?
commonly written as. 1:500,000. One unit of length on the map represents 500,000 of that same unit on the ground. For example, 1 inch on the map = 500,000 inches on the ground. One cm on the map represents 500,000 cms on the ground.
What does the scale 1 500000 mean?
What does the scale 1 2000 mean?
The measurement of 10 mm on the plan represents an actual size of 20000 mm or 20 m (2000 x 10 mm). An actual size of 48 m or 48000 mm is shown on the plan as 48000 ÷ 2000 = 24 mm.
What do the lines on a scale mean?
Read a Scale With Lines There are 16 ounces in a pound, so a small scale that weighs in pounds and ounces would have the longest lines at the pound marks, slightly shorter lines to mark quarter pounds (4, 8 and 12 ounces) and the shortest lines to mark ounces between the quarter pounds.
What scale is usually used for topographic maps?
Your map’s scale legend will always be at the bottom. For USGS topographic maps, 1:24,000 is the scale most often used. Maps based on metric units use a scale of 1:25,000, where one centimeter equals 0.25 kilometers. You’ll find most of the United States mapped at the 1:24,000 scale, with only a few exceptions.
What is the most common scale on a topographic map?
7.5-minute maps. The best known USGS maps are those of the 7.5-minute,1:24,000-scale quadrangle series.
