% add path to matlab functions:
addpath ('C:\Matlab_download\m_map1.4\m_map\');
m_proj('lambert','long',[90 146.64],'lat',[-12 14.15]);
[CS,CH]=m_etopo2('contourf',[-10000:100:0 ],'edgecolor','none');
m_gshhs_f('patch',[.7 .7 .7],'edgecolor','none');
m_grid('linest','none','tickdir','out','box','fancy','fontsize',16);
colormap(m_colmap('blues'));  
caxis([-10000 000]);
[ax,h]=m_contfbar([.70 .95],.83,CS,CH,'endpiece','no','axfrac',.05);

Hi,

Thank you very much for the link but it is not included in my figure when I added it in the code. Do you know how to do that?

% add path to matlab functions:
addpath ('C:\Matlab_download\m_map1.4\m_map\');
addpath ('C:\Matlab_download\borders_v3.1.2\borders\');
borders('indonesia','facecolor','#808000');
hold on
m_proj('lambert','long',[90 146.64],'lat',[-12 14.15]);
[CS,CH]=m_etopo2('contourf',[-10000:100:0 ],'edgecolor','none');
m_gshhs_f('patch',[.7 .7 .7],'edgecolor','none');
m_grid('linest','none','tickdir','out','box','fancy','fontsize',16);
colormap(m_colmap('water'));  
caxis([-10000 000]);
[ax]=m_contfbar([.8 .95],.82,CS,CH,'endpiece','no','axfrac',.03,'xticks','xticklabels');
title(ax,'Depth (m)','fontsize',16)
m_ruler([.8 .95],.75,'tickdir','out','ticklen',[.007 .007]);
m_northarrow(94,-9.2,4.5,'type',4,'aspect',1.5,'linewi',1); 
set(gcf,'color','w');

Hi Jonathan,

I understand that you would like to add the border of Indonesia on top of the map you have plotted. Have you heard about the "Mapping Toolbox"? I have tried using it on MATLAB R2023a and copied the 'latitude' and 'longitude' data from your code snippet:

%importing land data

land = readgeotable("landareas.shp");

figure;

newmap;

geoplot(land);

geolimits([-12 14.15],[90 146.64]); %from the code shared

As you can see, the borders are accurately plotted using the 'Mapping Toolbox'. There are also ways to customize the appearance of the borders, and I recommend referring to the documentation for more details. Here are some resources that might be useful:

These resources should provide you with valuable information to help you overcome the issue you are facing.
