Based On Spatial Data Integration Technology Of Land Surveying Sharing Management Applications And Research

In the recent years, along with the rapid development of surveying and mapping industry, as an important component of spatial information, the land survey data has accumulated a lot of data and results, and it has provided a lot of original data to the national economic construction, but at the same time, the using efficiency of the data is low, the management way is lagged behind, to some extent, its scientific value is also restricted, therefore, to the administrative department of land and resources, it is of great significance about how to realize the effective management and application of the land survey data result. At present, there are two management means of the land survey results, one is based primarily on relational database to storage and organization, and another is based on a spatial database-Geo-Database to storage and organization. The two methods each have its advantages, but there are also many sharing problems.This thesis took the existing problems in the land survey results management and application as the starting point, combined with the sharing needs of the land surveying results, the mainstream domestic and international land surveying data sharing technologies were studied and analyzed, and the land survey results managing system was researched and designed based on the spatial data integrating and sharing technology.This thesis expounded the related concepts of the land survey results data sharing, and the basic theory and key technology of the land survey results sharing were taken as the breakthrough point. According to the user’s sharing demands to the land survey results data, the spatial database was introduced as the organization form of the land survey data, and then on the basis of the basic conceptual understanding of the spatial database, the design principles of the land surveying results, the contents of the system composition and the design methods were researched, and the detailed design method of the land survey results spatial database was given in the thesis. Then based on the deeply research of the users’needs, XML technology and plug-in development technology combined with the spatial database application were used, which had solved the problems of the land survey result data sharing in the complex distributed heterogeneous network environment. Combined with the actual situation of the land survey administration departments, the land survey result data quality inspection and spatial analysis functions were joined in, the management mode and data quality inspection strategy based on the spatial database were given, and the land survey results management and application platform with scalability and configurability was designed and developed, so as to enrich the connotation of the land survey results sharing.
