Recently, the Government issued Liaocheng "on further work on surveying and mapping" (hereinafter referred to as "views"), to further strengthen the basis for the construction of geographic information resources, and effectively improve the level of mapping to provide security services.

     "Opinions" as requested in the city area to engage in surveying and mapping activities, it is necessary to use the city's reunification and the third C-class standard of GPS network, counties (cities, districts) District, the four D-class, such as GPS and leveling network control network, such as results, due to construction and scientific research, as well as the major projects needed to establish a relatively independent of the coordinate system must be submitted for approval step by step in accordance with the law and should be linked to the control network. To continuously enrich the types of fundamental geographic information resources and content, before the end of the "digital Liaocheng" geo-spatial framework (national pilot) construction, 8715 square kilometers domain Liaocheng 1:1 million, 1:5 million and 1:25 million, based on Geographic Information data covering the whole. Counties (cities) in 2010 to complete the county Planning District 1:500 topographic maps measuring system, measuring 1:1000,1:2000,1:5000 downsizing or new topographic maps, and form the basis of multi-scale mapping series results. To create a basic geographic information database, the realization of multi-scale, multi-type data based on geographic information to effectively manage and, in conjunction with social work, payment of application platform and build a county-wide platform for geo-spatial framework. "Digital Liaocheng" public platform for geospatial information 1:500 scale topographic map data elements for a framework to update every 2 years 1 ,1:500-1: 2000 scale topographic map update cycle not exceeding 3 years to ensure that the basis for mapping the results of the current situation.
