To display a specific region in Africa, such as a small lagoon in Tunisia, you can use MATLAB's mapping toolbox along with geographic data specific to that region. Here's a basic example to get you started:
matlab
% Define the latitude and longitude boundaries for your region of interest
latlim = [YOUR_MIN_LATITUDE, YOUR_MAX_LATITUDE]; % Replace with actual values
lonlim = [YOUR_MIN_LONGITUDE, YOUR_MAX_LONGITUDE]; % Replace with actual values
% Load coastline data for Africa
load coastlines
% Plot the coastline
figure
plot(coastlon, coastlat)
hold on
% Set the limits to display your region of interest
xlim(lonlim)
ylim(latlim)
% Add title and labels
title('Region of Interest in Tunisia')
xlabel('Longitude')
ylabel('Latitude')
% Optionally, add markers or other annotations for your lagoon
% Add a marker for your lagoon
lagoon_lat = YOUR_LAGOON_LATITUDE; % Replace with actual value
lagoon_lon = YOUR_LAGOON_LONGITUDE; % Replace with actual value
plot(lagoon_lon, lagoon_lat, 'ro', 'MarkerSize', 10, 'MarkerFaceColor', 'r')
% Add any other annotations or data points as needed
% Optionally, you can customize the appearance of your plot further
% Save the figure if needed
% saveas(gcf, 'region_of_interest.png')
% You can also use functions like geoshow or geoplot for more advanced mapping features
% Example:
% geoshow('landareas.shp', 'FaceColor', [0.5 1.0 0.5]);
Replace the placeholders (YOUR_MIN_LATITUDE, YOUR_MAX_LATITUDE, YOUR_MIN_LONGITUDE, YOUR_MAX_LONGITUDE, YOUR_LAGOON_LATITUDE, and YOUR_LAGOON_LONGITUDE) with the actual latitude and longitude values corresponding to your region of interest and the lagoon you're studying in Tunisia.
This script will plot the coastline of South Africa and mark your lagoon on the map. You can further customize the appearance and add additional data as needed. Make sure you have the Mapping Toolbox installed and properly set up in MATLAB to execute this code.
