An integrated system enables timely and accurate updates of the spatial and business data, improving land usage and promoting local economic development in a Chinese city

The city of Ziyang, located in the centre of Sichuan province in China, is an important industrial hub. Covering an area of 7,692 sq km and an overall population of 5.039 million, the city consists of 171 counties, 2,815 villages and 115 communities. The topographic feature can be divided into three types: low mountain, hill and river alluvial dam. Previously known as a major hill agricultural producer, Ziyang has transformed to emerge as a city hosting four major industries — vehicle manufacturing, food, pharmacy and textile industries. The scale of production is increasing rapidly, leading to further economic and social development in the region.

The need for a new cadastral system
Before 2011, the Ziyang National Land Resources Management Department (ZNLRMD) was in the need of a new cadastral system which could fulfil various requirements at various land management levels. The new system was to help local land agencies improve their work efficiency with a more organised and standardised framework.

In December 2011, the city decided to go for a new cadastral system and the work was contracted to KQ GEO Technologies. In the next 10 months, KQ GEO customised the Ziyang ONE MAP Urban Cadastral Information Management System and its integrated supervision platform for the ZNLRMD. Today, the system is used for regular cadastral management operations. At different levels of administrative regions, the related data of land registration (including graphic and attribute data, digital archives etc.) follows the same standards framework during collection, processing, assessment, management and application.

How the new system works
The Ziyang ONE MAP Urban Cadastral Information Management System includes a spatial reference system, projection method conversion as well as data collection, editing, change query and other functions, compatible with various data formats. The map and text integrated management mode fulfils the e-governance requirements. While the authorities can use the data statistics and analysis as a tool for decision making and multi-purpose and multi-scale spatial data management, the system makes way for office automation too which is standardising the process of land registration, including the urban land data and development. Interface and data conversion functions is expected to help data linking and transfer while connecting to other systems for simultaneous view.

A new sub-system or system upgrading can also be developed based on actual management needs. System safety management and maintenance functions will provide a complete and dynamic cadastral database building, maintenance and update functions, as well as intelligent security measures, which will ensure the system’s operating stability and safety.

Through the Ziyang ONE MAP Urban Cadastral Information Management System, the city is reaping benefits such as:

  • Faster approval for business establishment’s in land registration process
  • Integrated library management of present library, temporary library and history library
  • Virtual Reality technology for 3D visualisation management of cadastral archives
  • Web GIS technology for graphic and attribute data sharing
  • Digital ID recognition technology for efficient system user authority control
  • Component technology for providing secondary development interface

The ONE MAP system enables timely and accurate updates of the spatial and business data, thus improving the condition and environment of land exploitation and utilisation, optimising the land market and promoting local economic development. Efforts are on to integrate it with the National Land Registration Information Monitoring and Assessment System.
