What does 1 24000 mean on a topographic map?
It is given as a ratio of inches on the map corresponding to inches, feet, or miles on the ground. 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 a map scale of 1 25000?
There is a standard ratio format for map scales e.g. “1: 25,000”. The first number is the unit on the map and the second number is the distance in real life of the same unit so 1: 25,000 means that 1cm on the map corresponds to 25,000 cm on the ground. This means that 2.5 cm is equal to 500 km.
Why would a town planner use a map at the 1 24000?
The map at the 1:24,000 shows the town close-up in more detail. The map at the 1:250,000 scale shows the town in too much detail.
Is a 1 24000 scale map larger or smaller scale than a 1 100000 scale map?
Most of Alaska has been mapped at 1:63,360, with some populated areas also mapped at 1:24,000 and 1:25,000. The 1:24,000 scale is fairly large. They would be omitted, usually, from maps in the 1:50,000 to 1:100,000 scale range; these maps cover more area while retaining a reasonable level of detail.
What does 1 20000 mean on a map?
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.
How do you find the scale on a topographic map?
Use the scale bar found at the bottom of every NRCan topographic map to determine distances between points or along lines on the map sheet.
What type of scale is this 1 20000?
Understanding Map Scales
| Scale | 1 inch represents approximately | Approximate Square Miles to a Typical Map Sheet |
|---|---|---|
| 1:20,000 | 1,667 feet | 71 |
| 1:24,000 | 2,000 feet (exact) | 49 to 70 |
| 1:25,000 | 2,083 feet | 49 to 70 or 98 to 140 |
| 1:50,000 | 4,166 feet | 197 to 282 |
Which of the following global trends best exemplifies the concept of sustainability Unit 1?
Which of the following global trends best exemplifies the concept of sustainability? An increase in the use of electric vehicles, because their reduced emissions result in less environmental pollution.
What is the scale of a USGS topographic map?
The phrase “USGS topographic map” can refer to maps with a wide range of scales, but the scale used for all modern USGS topographic maps is 1:24,000.
How big is a 1 : 24, 000 topographic map?
A 1:24,000 map is large and provides a lot of detail about the area — it will include buildings, campgrounds, ski lifts, among other things. You may also see footbridges and private roads on a map of this scale.
How does a US Topo Map look like?
Arranged in the familiar 7.5-minute quadrangle format, digital US Topo maps are designed to look and feel (and perform) like the traditional paper topographic maps for which the USGS is so well known. In contrast to paper-based maps, US Topo maps provide modern technical advantages
What does contour mean on a USGS topographic map?
Basically, contours are imaginary lines that join points of equal elevation on the surface of the land above or below a reference surface, usually mean sea level. The phrase “USGS topographic map” usually refers to standard quadrangle maps with scale between 1:10,000 and 1:250,000.
