So, I can say ratio and RF would be 1:100000 and what I am try to explain is 1cm on map equal to 1,00,000cm on the ground.
To convert ratio scale to stated scale and stated scale to ration scale, all you need do is simple multiplication or division. So if I want to convert from stated scale to ratio scale. I need to simply multiply.
However if I want to convert from the ratio scale back to the stated scale. I need to divide.
Now again we are taking about scale and mapping there can be two kinds of scale small scale maps and large scale map small scale maps and large scale map have a basic different so let’s do the by example and that would be the best way to explain. This
Small Scale Maps | Large Scale Maps |
I say for small scale 5cm=500 kilometers on ground. | I say 5cm on map equal to 500 meters on ground. |
If it is small scale map I draw thematic map, because my 5cm= 500 kilometers, basically cover large area. | 5cm=500 meter set draw a region of city or say from my school to my house the distance between the school and house area was small but given more information. Covers smaller areas with detailed information. |
If you have say world map that here on a world map I can just marked the city of Delhi as dot. | If it is large scale map I can draw the entire city of Delhi. I can draw it’s urban pocket, slum pocket etc. |
The small map explain very large area | Provide detailed information for same region and they are mainly topographic map. |
