Paper Abstract

Map annotation is an important information representation method in computer-aided cartography and GIS. It is a supplement for map symbol system. With the development of computer technology, the Automatic Placemen of Annotation for map becomes a hotspot subject in computer-aided cartography. Usually, map Annotation is divided into three kinds: point feature, line feature and area feature. Specifically, the Placement of Annotation in Area Feature has being discussed by some scholars and many kinds of algorithms are given, mainly referring to the angle of the Annotation Placement. This paper discusses the Placement of Annotation in Area Feature within a point of view of the spatial geometric structure of the map, gives a new algorithm based on Map Spatial Geometry Information Measurement to complete the placement of annotation and compares the research results with the others.
