Research Of Data Integration In The Northeast China Geological Survey “One Map”

As countries to increase financial input in geological survey work, especially the "big investigation of land and resources", "special survey of geology and mineral resources assessment", "nine big plan" and other major projects, the degree of northeast geological survey work in Daxing Anling metallogenic belt and liaodong JiNa metallogenic belt two important metallogenic belt had the very big enhancement, but on the scope of the national it had low degree, and on the regional distribution is very uneven, characterized by the south-high and north-low and the east-high and west-low. Based on the current economic and social development process, characteristics of geological work in northeast China for the geological work in the new situation and new requirements, in the northeast China geological survey area layout and provide advice and a scientific basis for arrangements of macro.You need more detailed and complete project work degree such as the basis of geological and mineral survey data information as support.The improvement of degree in geological work, the increase of the difficulty in geological prospecting, increased investment, the urgent demand, pay more attention to the work plan for geological refinement, more comprehensive and coordinated, the surety, goods and material inputs such as scientific rationality. System combing business processes of geological survey work deployment, comprehensive data sources, according to the deployment decision of information. Can support the geological investigation term plans, avoid duplication deployment, reasonable management project, promote the informatization of geological management work.Northeast geological survey "One Map" database involves wide subject, large amount of data, based on the analysis of the past many years working in the database construction and the accumulation of several degree, especially periodic and complexity, the need to solve by the data integration technology. By integrating a variety of different formats data to complete the work plan for work and GIS application, so the multi-source data integration method is to realize "one map" key technology of application integration. Mentioned in the present paper studies the application of direct access to the data integration technology, MAPGIS K9 for GIS software platform, using spatial data engine(SDE) middleware technology and geographical spatial database built the northeast geological survey "one map" deployment of data center, this paper discusses the use of MAPGIS for data warehousing, data migration, data statistics, the practice of thematic mapping and other integrated application, improve the working efficiency, this paper introduces the spatial data quality evaluation method in the practical work and "one map" database of data quality checks.
