what is a medium scale map and it's resolution,range
Answers
Answer:
Explanation:
Simply defined, scale can be expressed as the ratio or proportion between a distance on the aerial photographs (or maps) and the actual distance on the ground or land surface. It is a ratio that could represent any unit of measurement and this ratio is called the Representative Fraction (RF). A scale usually is given as a fraction or a ratio (i.e., 1/10,000 or 1:10,000) and this "representative fraction" scale means that 1 unit of measurement on the map—1 inch or 1 centimeter—represents 10,000 of the same units on the ground. A scale of 1:40,000 means 1 inch on the photograph equals 40,000 inches on the ground, or 1 centimeter equals 40,000 centimeters on the ground.
If the scale were 1:63,360 then 1 inch on the aerial photograph (or map) would represent 63,360 inches, or 1 mile, on the ground (63,360 inches divided by 12 inches equals 5,280 feet, or 1 mile). The first number (map distance) is always 1.
The second number (ground distance) is different for each scale; the larger the second number is, the smaller the scale of the map. "The larger the number, the smaller the scale" sounds confusing, but it is easy to understand. So, a small scale map such as 1:1,000,000 shows a large area, but shows it in less detail. A large scale map such as 1:24,000 only shows a small area, but it shows it in great detail.
A medium scale map and it's resolution, range.
Explanation:
- A map is drawn to show the earth from a distance and they are classified according to the scale and the content and the deviations and the topographic maps show the background of the earth in terms of the geologic and soil and the maps can be of small, medium and also large scale.
- Depending on the plane of coordinates and the map projection systems. A medium-scale map id one that is made at a scale of 1:600,000 to 1: 75,000, while those of the large scale maps are 1:25,000 or larger and that of the small scale map is about 1:1,000,000 or smaller.
