Currently there are digital anatomical atlases of the human body capable of providing interactively information on anatomical structures. These models, can use vector or raster representations. In both cases they present limitations. Geographic information systems (GIS) have the characteristic of operating simultaneously with spatial and alphanumeric information. GIS features give the ability to operate efficiently with spatial information and conduct spatial analyses that combine the location of objects with their alphanumeric attributes. In this work a three-dimensional GIS model of the human body was developed. The model integrates vector and matrix representations allowing the exploration of the human body, both on surface and in its interior. This system offers a high degree of interactivity and an accurate access to the information within the human body. The results demonstrated the relevance and interest of the developed system in the study of the human body.
