xyz座標のある点群データのDSM画像が作りたいです。解像度は10㎝程度のものが作りたいのですが、グリッドごとに高さを与える処理がわかりません。2000*1800のグリットシートを作ろうとしています。

clear;
xsize=200
ysize=180
Xsize = xsize*10;
Ysize = ysize*10;
line = [1:Xsize];
code = [1:Ysize];
[X,Y] = meshgrid(line,code);
[X1,X2] = ndgrid(line,code);
figure()
[X1_ndgrid,X2_ndgrid] = ndgrid(1:Xsize,1:Ysize);
Z = zeros(Xsize,Ysize);
mesh(X1_ndgrid,X2_ndgrid,Z,'EdgeColor','black')
axis equal;
% Set the axis labeling and title
h1 = gca;
h1.XTick = [1:Xsize];
h1.YTick = [1:Ysize];
xlabel('ndgrid Output')
end
