In the field of modern geographic information systems (GIS) and three-dimensional visualization, oblique photogrammetry data (OSGB format) and 3D Tiles format are two widely used data formats. However, converting OSGB data to 3D Tiles format for loading and display on platforms such as Cesium has always been a challenge faced by many developers and data processors. To solve this problem, many efficient and easy-to-use OSGB to 3D Tiles tools have emerged on the market, aiming to help users complete data conversion tasks quickly and conveniently. After experiencing many tools, the blogger found such a free and practical tool - GISBox.
I. Application scenarios
(1) Geographic Information System (GIS): In the field of GIS, 3D Tiles format is widely used for three-dimensional map display, while oblique photogrammetry data (OSGB format) is the main means of obtaining high-precision three-dimensional models. With this tool, GIS developers can easily convert OSGB data to 3D Tiles format for display on platforms such as Cesium.

(2)Urban planning and management: Urban planning departments can use this tool to convert oblique photogrammetry data into 3D Tiles format for the construction and management of urban three-dimensional models.

(3)Virtual Reality (VR) and Augmented Reality (AR): In VR and AR applications, the efficient loading and rendering characteristics of the 3D Tiles format make it an ideal data format. With this tool, developers can quickly convert oblique photography data into 3D Tiles format for building immersive virtual environments.

1. Advantages of GISBox (1) Lightweight model: OSGB format models are often huge in size and difficult for general devices to load, resulting in problems such as failure to load or long loading times; and many oblique photography 3D formats and frameworks do not support compatibility, which is very unfavorable for the interoperability and application of 3D data. GISBox provides lightweight services, supports top-level reconstruction, fixed-point compression, and KTX2 texture compression functions. Even oblique photography models with extremely large volumes and containing files of hundreds of billions of files can be easily loaded in seconds after using the lightweight function.

(2) Real-time oblique photography editing: GISBox supports real-time editing of oblique photography (OSGB format). Users can quickly operate on data, reduce waiting time in traditional image editing, and greatly improve work efficiency.
It provides a "broken surface repair" function that can adjust the damaged area and restore the smoothness and continuity of oblique photography; it supports the "riverbed depression" function, which adjusts the river area in the oblique photography to make it conform to the height changes of the actual terrain, providing more realistic terrain data support for related application scenarios and improving the accuracy of analysis.

(3) Free service publishing: GISBox supports a variety of mainstream publishing protocols, including 3DTiles. After publishing, the service address will be automatically generated and can be used directly in Shanhaijing visualization, and the whole process is free of charge. The unique collection service publishing function allows users to combine multiple services together for unified publishing and management, which greatly improves data management efficiency and reduces repeated operations and maintenance difficulties.

III. Conclusion
In summary, it is not difficult to see that GISBox is an efficient and easy-to-use oblique photography data conversion tool, which is suitable for various application scenarios that need to convert OSGB data into 3D Tiles format. Whether you are a GIS developer, urban planner, or VR/AR application developer, GISBox is undoubtedly a recommended choice.
