Design of marker symbol database for forestry mapping based on information share.

YAO Shan;FENG Zhong-ke.Institute of GIS,RS & GPS,Beijing Forestry University,100083,P.R.China.  
In order to avoid that the symbols designed by GIS software have not the unified data format and can not be used in other systems,from the point of information share,the authors put forward that the symbols can be extended to a kind of font.The authors designed the TrueType font forestry marker symbol database by the algebraic method.The marker symbol was created by the Font Creator Program directly and the marker symbol was mapped by the GIS software.The creation and the mapping of the symbols were seperated.So the symbol database can be used conveniently in different GIS systems,and it is the foundation for the symbol information share and cross-platform forestry mapping.
