MATLAB: How to draw map in app designer

appdesignermapMATLABuiaxesworldmap

hi, I was trying to draw a map in app desinger

worldmap(app.UIAxes,'World'); but it reports error message.

so I searched and found there is one post saying that map axes cannot be used in uifigures.

https://www.mathworks.com/matlabcentral/answers/362991-how-can-i-use-plotm-from-the-mapping-toolbox-in-appdesigner

If i really want to plot a map and some other points with lat/lon on the axes of the add designer (which makes the app look more professional), is there any work around?

Thanks!

There is no axes input to the worldmap function (unfortunately). The function will create a new figure to display the map. After the figure is created, you can copy it to your app axes and then delete the figure created by worldmap().

h = worldmap('World');  % Store the output handle!
hCopy = copyobj(h.Children, app.UIAxes);  % Copy all of the axis' children to your app axis
delete(h.Parent) % get rid of the figure created by worldmap()

Since the worldmap function does not currently support setting parent axes, you'll have to create the plot in an external figure, make all needed changes, and then copy it to your app's axes. Here are instructions.

To center the plot on the pacific ocean, set the lat and lon limits using worldmap(latlim,lonlim).

map = shaperead('landareas.shp', 'UseGeoCoords',true);
worldmap([-45 80],[0 360]) % approximately centered over the pacific
geoshow(map)

Then copy to your app axes. See this comment below for details.

Then draw rectangle.

h = drawrectangle(app.UIAxes);  % supply your axis handle

MATLAB: How to import axesm into app designer

To import a map axes, it is only sufficient to change the parent of a map axes as follows:

% ... MapAxes is created in a new figure
% Change the Parent of the map axes
TempParent = MapAxes.Parent;
MapAxes.Parent = UIAxes.Parent;
% fit the size
MapAxes.Units = 'pixel';
MapAxes.Position = UIAxes.Position;
% delete the initial temperory UIAxes
delete(UIAxes);
% delete the temperory map figure
delete(TempParent);
