The Multi-Resolution Characteristics of Spatial Data in Vietnam Land Administration

Corresponding to the characteristics of multi-discipline and multi-level management, land administration always requires and acquires spatial data at very different spatial and thematic resolution. This particularity leads to many problems in spatial data acquisition and data management such as: inconsistency and difficulty in exchanging data between data sources and application disciplines. There are many researches in the direction of multi-resolutions to solve above questions. However, the adequate solution only comes out when the multi-resolution characteristics are quantified for a certain application. This paper has the objectives to quantify the multi-resolution characteristics of spatial data in Vietnam land administration. This quantification bases on the analysis of function, role of each discipline and administrative management level for land administration system. To verify the use of the quantification results, a case study of generalization, acquisition of land use data between disciplines and management levels is carried out at a local level.
