Drawing Contours on globe/world map

I have designed a software for computing relative antenna gain of satellite coverage/foot prints. The software takes latitude, longitude and gain as inputs and interpolates relative antenna gain in between the contours and generates contour plots. Pls tell me how can i display these contour plots on the globe according to the input latitude and longitude.

Hi somayyah Can you provide me the exact way or technical literature regarding your work. As I am also struggling with similar problem. I also want to know where are you in this problem right now?

Regarding your flag: why do you want to delete this question? It is more than 8 years old at this point. What harm is it doing?

Just in case you decide to edit away your question: don't bother, I've made a copy below and the site admins can generally restore your edit, so you don't even have to try.

Thanks for reaching out to me. Regarding your query, as you said my question isnt doing any harm but its too much detailed and doesn't truly reflect the actual problem I was facing with the plot then. That's why I wanted to edit it first but I couldn't because of associated product tag. So Thought of deleting it instead. Pls let me know if you can help me with that

Why would detaail be a problem? There are many detailed questions on this site. If someone in the future happens to have this detailed question, they will be happy to find a suggestion. You can ask a new question with a different scope if you want, but I don't see what benefit deleting this question would have. I will therefore remove the flag.

Hi,

I'd make use of the m_map toolbox for this. Rather than give you exact code, (read: I cant remember offhand) let me rather explain loosely how to go about it.

First get the toolbox http://www.eos.ubc.ca/~rich/map.html or do a Google search on "m_map" Then make a plot of whatever section of the world you're interested in.

Next, transform your longitude and latitude to coordinates on the plot.

Finally overlay a contour or contourf plot of your data on the figure.
