problem inserting some site coordinates on a map created by geoshow

Hi,

I simply used 'geoshow' to have a map with lat and lon:

geoshow(lat,lon,Z,'DisplayType','surface');

the lat, lon and z are coming from a DEM file.

now I want to mark some locations on this map like:

geoshow(HEAD(:,1), HEAD(:,2),'displaytype','point','Marker', 'o')

and the HEAD is lat and lon for 76 sites which obviously are located in the first map.

I can have both in separate maps but I can not plot them in one. Can anyone help me?

Hi,

Assuming the variables ‘lat’,’lon’,’Z’ are correctly initialized, you can plot the markers on the surface map, using figure handle through ‘gca’.

figure; 
load('korea'); 
worldmap(map, refvec); 
geoshow(gca,map,refvec,'DisplayType','surface'); 
load coastlines; 
geoshow(gca,coastlat,coastlon,'displaytype','point','Marker', 'o');
