             abstract = "A complete solution for creating an entire planet by combining 
                         different types of elements from an intuitive specification is 
                         still an open problem. High-level techniques are at the core of 
                         the solution for this issue. In this context, our work aims to 
                         contribute for the development of high-level techniques for 
                         landscape creation by the proposal of two approaches. The first 
                         deals with the manipulation of the position of landscape elements 
                         (according to some criteria), and the second is related to the 
                         generation of terrains from two new data-driven methods. In 
                         particular, we introduced a flexible method for resizing a 
                         landscape specification keeping the overall appearance. It is 
                         based on the insertion and removal of objects followed by scene 
                         adjustment (enlargement or shrinking). Furthermore, we introduced 
                         two data-driven techniques for terrain synthesis. They are 
                         developed over the same intuitive control approach, and they take 
                         advantage of the geometric nature of the data for improving the 
                         synthesis. The first technique is a patch-based algorithm, with 
                         new optimization structures for patch choice, and a new patch 
                         insertion approach (both based on the geometric nature of the 
                         data). The second is a pixel-based method, based on a graph of 
                         exemplars in multiresolution.",
