The Integrated Management of Information about the Geodetic Point Fields—A Case of the Czech Republic

Abstract

The geodetic point fields play a crucial role in measuring a terrain, in surveying, and mapping applications. Due to the rapid development in the domain of information technologies, it makes sense to consider using the database and web technologies to manage and disseminate the available information about the geodetic point fields. The paper presents the creation of a spatial database which integrates the information about the various kinds of established geodetic point fields (horizontal, vertical and gravitational) with the aim of enabling their effective management. Furthermore, based on the integrated spatial database, the prototype of the new information system of geodetic point fields has been developed. The functionality of the prototype also considers the requirements coming from the international efforts, i.e., the Infrastructure for Spatial Information in Europe (INSPIRE) directive. The prototype, based on Java Enterprise Edition (EE) technology, implements the features reflecting the cyber-security issues and ensures the modularity and scalability of the system, which is important for further development of the system and dissemination and accessibility of the information about the geodetic point fields via modern web technologies.

“…Control surveys serve as the basis for initiating or reviewing subordinate surveys for property boundary delineation [6], route and construction planning [7,8], engineering object displacements [9], cadastral and topographic mapping [10], as well as many environmental applications and cultural heritage preservation and monitoring [11,12]. They are indispensable as a reference framework for land administration systems, especially for georeferencing spatial objects [13][14][15]. Many scholars point out that the production and quality control of any geographical data and products requires references to the base geodetic network that realizes the CRS (Coordinate Reference System) and provides the consistent frame for GNSS users [5,16,17].…”
