First of all, in accordance with the requirementsof the construction of county-level land use planning database, the database constructiontechnology roadmap and operation process were formulated. Then, the characteristics ofspatial database, structure and model of spatial data was described. In addition Geodatabasein ArcGIS, which is used to construct land use planning database, was introduced. Then, inaccordance with the land use planning database construction process, some keytechnologies on the base of data processing, feature creating, data warehousing, attributeassignment, the metadata and Geo-spatial transfer format generation etc were discussed indetail. Finally, taking Baohe District of Hefei City as an example, according to theproposed route, the Database of the General Land Use Planning in Baohe District (2006-2020) database was completed. Dot NET, FME, XML technology and ArcGIS Enginemodule were integrated to complete this example of case based on ArcGIS. |
