making a area plot with lat,lon and a variable corresponding to that location

9 views (last 30 days)
I have latitude, longitude and temperature corresponding to those locations. How can I make a color plot in a way it show how temperature varies along that region? When I bring the cursor to the location I am interested at, if I can read the temperature, that would be much helpful as well.
Thanks, Thishan

You need to read about pcolor , surf .
[X,Y,Z] = peaks(50) ;
If lon, lat are your spatial coordinates and T is your mxn temeprature matrix:
surf(lon,lat,T) ; % if throws error, use T'

Chances are that dir() will return the file names in order by encoded date; you could sort() the names to be certain. It looks to me as if you would not need to use something like natsortfiles() from the File Exchange as you have a fixed number of digits for each field, and the date fields are arranged in a useful order already.

You will probably need to use either griddedInterpolant or scatteredInterpolant; then you would call the resulting function with an array of locations and plot the result.
