Hi to all,
i have a data set of international airports with latitude, longitude and
altitude. I was thinking of creating a 3D plot out of them, but haven't
succeeded yet.
With
plot3d(x=seq(min(traffic$lon),max(traffic$lon)),y=seq(min(traffic$lat),max(traffic$lat)),z=traffic$alt)
all i get is http://imageshack.us/photo/my-images/225/70758244.png/. What i
wanna get is a 3Dlike map of airports in the world. Am i using good
function to achieve that? Why are the points "lined" up and don't copy
their 2D shape (http://imageshack.us/photo/my-images/36/91660845.png/)?.
Thanks for replies or hints, i'm new to R and as a geography student i'm
especially interested in handling and visualizing geodata.
