Hello everyone!

I have a matrix which looks as shown in figure below.

The first two columns indicate the longitude-lattitude of the world. The third column indicates some value of a parameter (let's say temperture).

I want to create a world map, where the different values of the temperature can be indicated by some color values. Can anyone help me in doing that?

thank you in advance.

Hi Kumar,

From your question I understand that you need a function that can plot plot points on the world map and indicates temperature ranges. Please refer to the geobubble function in MATLAB. A nice illustrative example is provided in the same documentation that I think is in lines with your requirement.

Thanks
