interpolate walking survey data to grid using scatteredinterpolant and plot interpolated topographic surface in matlab

main.m
% Assume you have two variables, x and y, which represent the coordinates of your survey data,
% and another variable z representing the survey data itself.

% Create the scattered interpolant
F = scatteredInterpolant(x, y, z, 'linear', 'none');

% Define the grid to interpolate onto
[X, Y] = meshgrid(min(x):0.01:max(x), min(y):0.01:max(y));

% Evaluate the interpolant on the grid
Z = F(X, Y);

% Plot the interpolated topographic surface
surf(X, Y, Z);
xlabel('X');
ylabel('Y');
zlabel('Z');
