| With the progressing of the science and technology,the global economy developed rapidly,urbanization construction speed is also at a high level,large numbers of people go to the cities,to build urban building blocks at the same time.This resulting in the total amount of the rapid expansion of the information society,urban management is increasingly complex,and management tools requirements are also increasing.Faced with limited space resources,how to make it produce the greatest benefits is the most serious problem today’s society is facing.At present,computer software technology,geographic information technology continues to evolve,making the Android-based mobile GIS system platform becoming the hot topic in the field of municipal management,and related industries is also showing broad prospects.This thesis is based on the Android platform for mobile GIS research and application in municipal drainage Service.First the background of domestic and foreign municipal drainage services are analyzed,according to the municipal drainage pipe network information,occupies large memory,slow speed,scheduling and regulation not timely,many problems,deeply studied GIS system operation strategy and storage management techniques,and constructed based on Mobile GIS system with the system requirements and measures,the Android operating system,supplemented by the municipal drainage service system.And the Locationmanager,SQLite,Json,HttpClient,Android key technologies and methods,to the Android platform LMK storage strategy,for GC storage strategy,analysis of bitmap resources strategy for,comparison and optimization,to map data caching strategy slowed memory increase speed,improve the operation speed of the mobile GIS.The experiment proves that the system is reliable and meets the design target,and it can be applied to the municipal drainage system. |
