基于MapObjects的位图符号的设计及应用

Spatial Information Visualization play an important role in knowledge discovery, appropriate visualization methods contribute a lot for understanding the spatial information and mine essential laws and patterns. Spatial data often exit with either pixel or vector format or both formats, each of the formats has different characteristic in spatial information visualization. This paper, from the point of view of spatial information visualization, proposes a method that using bitmap to present point objects. This method is based on the ESRI MapObjects by implement MapObjects’ ICustomMarker interface. Experimentation shows this symbol benefits displaying point information.
