Family tree,official history and chorography jointly build the entire history datum in China.The family tree,also called pedigree,is much informative in society,ethnology,custom,geography,population,economy,people and religion.It is significant to carry the data mining and regularization work on family tree for reconstructing spatial-temporal pedigree,reproducing the civilization skeleton of China and developing the national culture as well as spirit.However,due to the lack of technology,the traditional record and expression pattern can not reflect the movement,rise and fall of the family in spatial and temporal space accurately.So Family Tree GIS conception was proposed and it is combined with GIS as its technology supporting.The spatial relationships underlying family tree are imposed and the reconstruction,integration and recurrence of the family tree is its core study content.In detail,Family tree data model and the spatio-temporal supporting framework are designed according to the characteristics of traditional family tree.And then,some key technologies used in building family-tree GIS are discussed especially such as SOA based on Web Service,XML and XML Schema technology,distributed GIS platform oriented the public and the Web 2.0,also technology of management and drawing mass vector data,technique of generation SVG based on DOT,asynchronous network calling and interaction based on AJAX,XML are discussed.Thirdly,the framework of family tree GIS was proposed and the prototype system was introduced in this paper.Finally,taking a family-tree as a study case,building,analysis and representation of the family-tree is discussed.The experiments have shown that the family tree GIS we proposed is a good approach for the study of conventional family tree,and it will be helpful for future researches on family tree.
