how to amke 2D map in matlab

hai there,

i have ocean current data ,longitude,latitude and velocity..i need to generated 2d map to represent the velocity by color..so what the best function to create?? using surf or colormap? or anything else

Answer 1

[Sean de Wolski]

Do you have components of velocity or just magnitudes?

Here are a few tools you may be looking for:

doc quiver
doc scatter

Answer 2

[Walter Roberson]

Are you using the mapping toolbox? Getting the map shape right taking in to account spherical geometry is best left to the mapping toolbox.

i have lat,longitude, u,v, speed and direction..i already plotting the direction using quiver function..but i want to represent the velocity using color to show the magnitude value
