Applying the image within Matlab
After the image is generated it can be used as a background image in Matlab. See the example below of how to do this:
% load your geoimage
filename = 'p:\1230691-sri-lanka\02_data\geo_image\overall'; % dont use an extension
[x,y,z,col] = georeference_image(filename);
% create the figure
figure; hold on;
plt1 = surf(x,y,z,squeeze(col));shading flat;
plt2 = scatter(Xpoint, Ypoints, [], Zpoints);
