Integrated Cartography Technique Based on GIS

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.
