I am looking at the following example from the MathWorks documentation: I want to modify the map and start location in the model accessed via the command: >> openExample(‘uav/UAVPackageDeliveryExample’); How can this be achieved?

This can most easily be achieved with a MATLAB script. The example code below changes the map to a location in London.

%% Change lat-lon used by QGroundControl map
dict = Simulink.data.dictionary.open('uavPackageDeliveryDataDict.sldd');
sect = getSection(dict, 'Design Data');
latlon = getEntry(sect, 'uavIC_latLon');

% Set lat-lon to London, then when you simulate with QGroundControl
% connection, it will show London map. You can then use QGroundControl
% to create and upload new mission in London
setValue(latlon, [51.5072 0]);

%% Change initial world position used by low-fidelity model during Simulation
lowFiPlant = 'MultirotorModel/Inner Loop and Plant Model/Low-FidelityModel/Quadrotor Plant';
% Check the world position parameter in block mask
open_system(lowFiPlant);
% Change initial position
