This work presents a method to construct featured 3D terrains using information gathered from their satellites images. This data is used as keys in an image-database search. These searches use wavelets for minimize disk space and improve searching speed. In order to compose the elements with trees or bushes, for example, we use the common billboard concepts embedded with transparent technique named alpha-channel.
