is it possible to use polybuffer to geopolyshape?

I've tried but it didn't work.

Thanks.

Show us your data and show us what you expect.

shape1 = geopolyshape({[37.4695   37.4719   37.4723   37.4698]},{[126.4470  126.4448  126.4452  126.4473]});
% In some case, it didn't make a rectangular so I used this code too
% shape1 = geopolyshape({[37.4695   37.4719   37.4723   37.4698 37.4695]}...
%  ,{[126.4470  126.4448  126.4452  126.4473 126.4470]});
geoplot(shape1)
polyout1 = polybuffer(shape1,5,'JointType','square');
hold on
geoplot(polyout1)
hold off

and I want to know what the number 5 means. meter or kilometer?

It depends on what your shape1 units are...

I solved this problem using projcrs. Thanks!
