Cadastral data is an important component in the modern land management system, used to build and spatially locate other data of the national land database; helping state management agencies, businesses and people easily access and use land information accurately, transparently and effectively. The objective of this study is to use Microstation and gCadas software to digitize and standardize maps - cadastral records, then combine GIS technology, use ArcGIS software to build and complete spatial data, attributes to build multi-objective cadastral data to serve modern land management. In this study, cadastral data was constructed from 159 cadastral map pieces, of which 76 pieces were at a scale of 1/2000, 83 pieces were at a scale of 1/1000 with 32,338 land plots combined with cadastral records of Dong Hieu, Nghia My, Nghia Thuan communes, Thai Hoa town, Nghe An province. The constructed data will provide spatial and attribute information such as location, shape, size and information of land plots quickly and with high accuracy, supporting land statistics and inventory, compensation for site clearance, planning for land management and use, etc., which is the basis for multi-purpose land management at the local level.
