Hi John,
I understand that you want to use the mobile accelerometer data. You can use the function “accellog” to obtain the data. You can also get data from the “poslog” function to get the latitude and longitude for the same duration. You may refer to the sample code below:
% Create a mobiledev object
m = mobiledev;
m.AccelerationSensorEnabled = 1;
m.PositionSensorEnabled = 1;
m.Logging = 1;
pause(30); % Pause for 30 seconds while data is being collected
m.Logging = 0;
[a, t] = accellog(m);
[lat,lon,t_pos] = poslog(m);
zAccel = a(:,3);
% Analyse and Process the data as you require
[lat_p, lon_p] = analyzeData(lat,lon,zAccel); % Your logic to get the points of interest
Once you have processed the required latitudes and longitudes, you can use “wmline” to plot the data on a “webmap”.
webmap;
wmline(lat_p,lon_p);
You can refer to the following documentation link for more details about these functions:

- poslog: https://www.mathworks.com/help/matlab/ref/mobilesensor.internal.mobiledev.poslog.html
- webmap: https://www.mathworks.com/help/map/ref/webmap.html

Hope this helps.
