Integrated cartography plays an important role in digital mapping. Based on Geographic Information System (GIS), this study presents an integrated cartography technique which consists of spatial data conversion, basal graph-object-oriented symbol design and seamless and adaptive map visualization. This technique is successfully applied for electronic navigation chart (ENC) mapping. In this research, basic graph-object-oriented symbol includes point-symbol design, line-symbol design and polygon-symbol design. In addition, adaptive visualization contains several essentials: rendering display, adaptive scale display, priority-based display, text annotation display, safe-depth display. Based on the above research, as a result, an ENC information software system has been developed. The main function modules include different scale spatial data conversing, field-data editing, graph-object-oriented symbol designing, map-viewer filling, dynamic pictures and character displaying, map layer controlling and database managing.
