After dowloading topo data (.tif) from I use "Imread". For plotting the data
It plots the 3D terrain data.
The size of the A is 194x424. It contains elevation data. I want to use slice command but in slice command there are x,y,z, and v.
After meshgrid the dimesion of the x becomes 3D and the same for y and z for 'slice' command. v is the function.
But as I stated my terrain data can not be converted for slice command. Is there anything that helps me?
Thank you

No. Your data cannot be sliced.
Perhaps you might want to contour() the data, and get back the contour matrix, and use something like to extract data from the contour matrix.

Thank you again
'improfile' can be good start for me but I need 2D plane. With 'improfile', only the line is taken into account. I want to give more information for my problem:
hold on
x2=[50 200 200 50 50]; %for the plane
y2=[50 50 170 170 50];
z2=[4200 3800 3800 4200 4200];
hold on
textscatter3(50,50,4200,"aircraft",'ColorData',[0.5 0.6 0.7]);
textscatter3(200, 170, 3800,"runway", 'ColorData',[0.5 0.6 0.7]);
I draw a 2D plane (red). The aircraft and the runway positions are given. I it possible to create a new map from the intersection of the red plane and the terrain?? Finally I try to create a 2D map. The terrain data in this map is given as for terrain =1 and freeterrain=0. It becomes A= [0 0 0 0 0 0 0 0 ......; 0 0 0 0 0 1 1 1 0 0 0...]]. Maybe it is like that:
Thank you,

I use this code to plot the intersection.
I appreciate your suggestion. Thank you
