Importing geographical maps in matlab

I wish to create an interactive map in Matlab. For that, I need to import a geographical map of Botswana in Matlab. I am getting stuck with that. Kindly do help

[Ojaswita]

Still awaiting any possible answers. I have used the worldmap and geoshow functions in Matlab but that does show the country boundaries. Please do help!

Using borders,

worldmap('africa')  % initializes a map
borders('countries') % outlines all countries
borders('botswana','r-','linewidth',2) % outlines Botswana in red
labelborders('Botswana') % labels Botswana

Thanks alot! But I get an error:

??? Undefined function or method 'borders' for input arguments of type 'char'.

Type

ver

in your command window, does it show mapping toolbox in the list of toolboxes that show up?

If it doesn't youll have to buy it to use these functions.

[Chad Greene]

Ojaswita, That error means Matlab can't find the borders function. Download it from the File Exchange site, place borders.m in your current Matlab folder, and the code above should work. You do not need the Mapping Toolbox to use the borders function.

I have downloaded the border.m from the following link: http://www.mathworks.com/matlabcentral/fileexchange/50390-borders

I added the folder using pathtool... and i run the exact same code as the one provided by Chad. And i still get the same error

I managed to draw the maps by doing some changes in the coding. I am now facing trouble with marking the cities with a marker point on the map. I have tried text, textm, plot, plotm, annotation and many others, but none of them give any result or error.

I downloaded the borders.m file from file exchange to draw the maps of different countries. I had an older version of MATLAB earlier and I used the pathtool to add the folder into my directory. It worked perfectly and I got my results using the following code:

    borders('botswana','b-','linewidth',2);  

    x = [-24.65; -21.17; -22.38; -23.1; -22.55; -19.98; -17.82; -21.7; -26.02; -24.41; -24.98];
    y = [25.91; 27.51; 26.72; 26.8; 27.13; 23.42; 25.15; 21.65; 22.4; 25.5; 25.35];
    cities = {'Gaborone', 'FTown', 'Serowe', 'Mahalapye', 'Palapye', 'Maun', 'Kasane', 'Ghanzi', 'Tsabong', 'Molopolole', 'Kanye'};

    plotm(x,y, 'x', 'MarkerSize', 10, 'LineWidth', 2)
    textm(x,y, cities)

Now I upgraded to MATLAB 2013a, and I try to run the same code (after trying to add the borders files in the directory using different methods), and I get the following error:

Error using referenceSphere The specified superclass 'spheroid' contains a parse error or cannot be found on MATLAB's search path, possibly shadowed by another file with the same name.

Could I get some light on how to sort this out, please please
