7 Geospatial ontology generalization and classification for geographic features category types for places hierarchy of categories Feature type Place name ( Toponym ) the meanings for place names reference functions as proper nouns topology the relations between classes the relations between instances reasoning rules Spatial relation Geospatial Feature Coordinate referencing standard for feature discernment general feature model position in coordinate reference systems geometry with coordinates

8 Concept and Functions of Place names The name itself contains and Indicates meanings It may change its meaning or referenced information Naming convention By nature of feature By shape of physical object By human name By combining name contains generic class By relative to other names popular name abbreviation By fiction Place Name Reference change code translation language translation ( phoneme ) ( meaning ) language translation synonymous alternative historical change Geographic location History ( diachronicity ) Common knowledge ( synchronicity )
