How to point out a city from a map image of world with longitude and latitude?
From this image, you can see the coordinate system for latitude and longitude: Unless you know the exact location (both pixel-wise and latitude and longitude) of a point on your map, you can't do anything with it. You just won't have enough information By x axis and y axis, do you refer to your image? What is the image of (like the whole world, or of a specific region)?
If it's of the whole world, then the coordinates would be: x = image. Width * (longitude + 180) / (2 * 180) y = image. Height * (latitude + 180) / (2 * 180).

I have the image of whole world. Here is the link if my image. Postimage.Org/image/35ghmr2sk – kamal Jul 12 at 3:42 Ok, then those conversions should work.
You might have to mirror along the y axis if you are drawing with the origin being at the top left corner, as my conversion uses the bottom left as the origin. – Blender Jul 12 at 3:47 some calculations are wrong may be because of map. Can you tell what is wrong.
Can you advice a map of width 800 which can give correct calculations. – kamal Jul 12 at 7:59 Yep, it's the map. Look where (0, 0) is on the map (the bloack dot should be in the ocean, but it's in the middle of Africa): img560.imageshack.
Us/img560/6660/worldmap800. Jpg – Blender Jul 13 at 1:39 Take a look at this map projection: en.wikipedia.Org/wiki/Equirectangular_projection – Blender Jul 13 at 1:51.
Latitude (shown as a horizontal line) is the angular distance, in degrees, minutes, and seconds of a point north or south of the Equator. Lines of latitude are often referred to as parallels. Longitude (shown as a vertical line) is the angular distance, in degrees, minutes, and seconds, of a point east or west of the Prime (Greenwich) Meridian.
Lines of longitude are often referred to as meridians. If you divide the circumference of the earth (approximately 25,000 miles) by 360 degrees, the distance on the earth's surface for each one degree of latitude or longitude is just over 69 miles, or 111 km. Note: As you move north or south of the equator, the distance between the lines of longitude gets shorter until they actually meet at the poles.
At 45 degrees N or S of the equator, one degree of longitude is about 49 miles. For precision purposes, degrees of longitude and latitude have been divided into minutes (') and seconds ("). There are 60 minutes in each degree.
Each minute is divided into 60 seconds.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
