hi, i have a shapefile (.shp) to be display in 2 different ways.Before and after simplification process.Therefore i applied reducem and bounding function.However the error is 'Reference to non-existent field 'BoundingBox''.Does anyone have an idea?

   %c = my shp location. 
   dc = shaperead(c,'UseGeoCoords', true,...
      'Selector',{@(name) ...
      strcmpi(name,c), 'Name'});

lat = extractfield(dc, 'Lat')';
lon = extractfield(dc, 'Lon')';
[latreduced, lonreduced] = reducem(lat, lon);

lonlim = dc.BoundingBox(:,1)' + [2.08 9.11];
latlim = dc.BoundingBox(:,2)' + [2.08 9.11];

Is it possible that the shape file contains only Point structures? There is no BoundingBox field for that case.

Yes. my shapefile contains point structure. I already tried others example (usastatehi -district of columbia) and boundingBox works on it. then i found out that num. of feature of my map different to the example.i tried to reduce num of feature by resize my shapefile but it not work. do you have any idea to solve it?

I would appreciate any help or direction in what I am trying to do. Thank you very much!

Resizing will not help if your shape is point structures; the documentation indicates that bounding box will not be created for point structures. You could possibly calculate a bounding box by taking max() and min() of the values.

ok i got your point. thanks for the help.
