An integrated photogrammetric and spatial database management system for producing fully structured data using aerial...

Area of Science:

• Geoinformatics
• Photogrammetry
• Database Management Systems

Background:

• Photogrammetric techniques provide accurate and economical 3D spatial data for GIS and map production.
• Challenges exist in storing, structuring, and managing spatial data from photogrammetry.
• Current GIS workflows struggle with coupled spatial and attribute data management.

Purpose of the Study:

• To evaluate the integration of photogrammetric systems with Spatial Database Management Systems (SDBMSs).
• To demonstrate how direct integration can improve efficiency and reduce costs in digital map production and updating.
• To present a novel software solution for seamless integration.

Main Methods:

• Reviewing the capabilities of SDBMSs for spatial data handling.
• Describing different levels of integration between photogrammetric workflows and SDBMSs.
• Designing, implementing, and testing a prototype software package (IPOSS).

Main Results:

• Direct integration replaces traditional digital maps with a unified spatial database.
• Spatial databases effectively manage both spatial and attribute data in a coupled manner.
• Integrated systems enable the creation of structured, OGC-compliant spatial data with topological relations during digitization.

Conclusions:

• Integration of photogrammetric systems and SDBMSs offers significant advantages for GIS.
• The proposed IPOSS software package demonstrates a viable solution for this integration.
• This approach enhances the usability and management of photogrammetric spatial data.
