Internet Database for Photogrammetric Close Range Applications

The paper presents the concept of an information system dedicated to storing, presenting and publishing via the Internet numerical and digital results of photogrammetrical measurements from various close range applications. The presented information system is not an on-line application for real-time Internet measurements. In the system a standard client-server model was applied. Three levels of access (system administration, limited and passive access) of entitlement were defined to protect the database and its structure. The structure of relations, concept and functioning rules were defined. In the system, a freeware Firebird® database server was used. It was serviced by Borland DelphiTM programming environment. The design stage was supported with CASE tools. The system is characterized by independence from native Microsoft Windows technologies, uniqueness, use of practical solutions and reduction of system limitations. The project met all relevant security standards. Applied solutions considerably reduced costs of the project.
