Research And Application Of GIS Based On Component Technology

The platform of"Transportation Economic GIS of Civil Aviation"is sub-product of civil aviation executing management and GIS technology. It can manage and visually analyze the information and data of air-transportation resources about distribution of cities, airlines, airports, ability of transportations, and other air-lines by geography range.The essay starts from development of GIS, analyzes application and development environment of GIS, introduce the COM technology and its development, focuses on providing the Com-GIS and it's characteristics and advantages and furthermore introduces and compares several GIS development platforms, last chooses MapX which is a Com-GIS software as development platform. Based on the analysis of executing situation of civil aviation, I did a lot of work on architecture design, function design, database design, system-in and system-out design, system detail design and pick up system development solutions of"Transportation Economic GIS of Civil aviation", and have a deep research in several fields including organization of map data, query of space data, and furthermore give some examples of major system implementation.
