Study of Symbol Library Data Structure and Algorithm Based on Property Unit
Wu Li · 2004
Spatial data symbolization is an important method for GIS data visualization. It involves the most computer work in GIS processing. Therefore, to promote the efficiency of spatial data symbolization is vital for enhancing the capability of GIS software. This paper has proposed an algorithm design based on property unit, taking into account the global optimization and symbol object orientation. A property-based data structure and algorithm is also proposed. Application results show that it not only has more advantages over the old algorithm, but also expands the functions of symbolization.
