Calculating Real Distance

  • If RF is 1:10000

  • Map Distance = 5 cm

  • Find Ground (Real) Distance?

If I have representative fraction that is given and the distance of the map, I can calculate the real distance of the map. I can calculate the real distance because when I say RF is 1: 10,000.

That means 1cm on map equal to 10,000cm on ground. If I have map distance which is 5cm, can I find out the ground distance if would be definitely 50,000cm. If you have 5cm on map can say it would be 50,000cm on ground so this is the simple formula to calculate the real distance.

I have the scale and better way to write this would be map scale by the ground scale would be equal to . So the real distance on a ground and the real distance on the map and the scale on the map versus the scale on the ground helps you find out the ground distance.

And finally this are some of commonly use conventional symbols. For settlement, graveyard for trees, grass for post office then boundary, road, railway so on there are the commonly use symbols you can see in each and every map. When accepted internationally those are called as conventional symbols.
