Thread Subject: Importing GSHHS data for a certain range

Hi all!
I'm using the gshss command to import GSHHS data.
I only want to import data for a certain range:

e.g.
latlim = [40 60]; %Latitude borders
lonlim = [01 20]; %Longitude borders
(central europe)


I use therefore this command:
MapComplete = gshhs(filename, latlim, lonlim);

Every struct in MapComplete data represents one land mass
(continent/island).
The biggest land mass in this case is:

Geometry: 'Polygon'
       BoundingBox: [2x2 double]
               Lat: [1x8110 double]
               Lon: [1x8110 double]
             South: -34.8304
             North: 77.7163
              West: -17.5338
              East: 190.3260
              Area: 7.9866e+007
             Level: 1
       LevelString: 'land'
         NumPoints: 8109
     FormatVersion: 3
            Source: 'WVS'
    CrossGreenwich: 1
          GSHHS_ID: 0

Even though I only wanted to import the data for central
europe this struct represents whole europe,asia and africa
because they are physically connected.

Is there any way to import only the range I want? Or do I
have to sort it out later?

Thanks!
Volker
