GISBox is a powerful 3D GIS data editing and conversion tool, which can easily convert various geographic data formats into 3D tiled formats (such as Terrain format) supported by Cesium. Below are the specific steps to tile DEM files to Cesium Terrain format using GISBox.
1: Select a new tiling task
Launch GISBox software and find the "Tiling" option on the main screen.
Click "New" to create a new tiling project. This step will initialize the task management screen, allowing you to set tiling parameters and add source files.
2: Select point cloud tile and add DEM file
In the tiling task window, select "Point cloud tile" as the tile type.
Click the "Add file" button and load the DEM file you want to convert. GISBox supports many terrain formats such as GeoTIFF, so make sure your file format meets your requirements.
Once the file is loaded, GISBox will automatically read the geographic information and elevation data.
3: Set Tile Attributes
In the Tile Task window, you can adjust the following attributes as needed:
Color Calculation: Select the Color Calculation option to generate tiles in pseudocolor or true color based on the elevation data.
Vertex Compression: Select the Vertex Compression option to optimize the size of the generated Cesium Terrain data and improve loading performance.
Resolution Settings: You can set the target tile resolution and level range as needed. This allows you to control the accuracy and capacity of the generated files.
4: Start Tile Task and Monitor Progress
Click the Start Task button and GISBox will start to process and tile your DEM file into Cesium Terrain format.
In the Task Management window, you can see the task execution in real time, including the progress bar and log information.
Once the tiling is completed, a corresponding Terrain folder will be generated, containing the tile result data.
Conclusion
Through the above steps, you can successfully tile your DEM file into Cesium compatible Terrain format using GISBox. Whether you are creating large-scale terrain visualization, developing virtual geographic environments, or conducting 3D spatial analysis, these efficient 3D tile data will provide powerful technical support for your projects.
GISBox significantly lowers the hurdles of 3D terrain data processing with its easy operation and powerful functions. If you are looking for an efficient and intuitive GIS data management and conversion tool, GISBox is definitely your best choice.
