In the field of GIS, Cesium has become one of the popular geographical data display platforms with its powerful three-dimensional visualization capabilities. Geotiff is a commonly used raster geographical data format and is widely used to store elevation, image and other data. How to convert Geotiff data to the Terrain format supported by Cesium has become a problem faced by many GIS practitioners and developers. Don’t worry, this article will recommend you a simple and efficient free tool—GISBox, which will help you easily complete the data conversion task!
- Why convert Geotiff to Cesium Terrain format?
Cesium’s Terrain format is a data structure designed specifically for three-dimensional terrain display. It loads quickly and presents realistic terrain effects, providing users with a smooth and fluid elevation visualization experience. Although Geotiff has rich spatial information, Cesium’s Terrain engine does not directly support it, so it needs to be converted to Terrain format before it can be loaded and displayed in Cesium.
- Use GISBox to convert Geotiff to Terrain. GISBox is a free toolbox specially designed for the GIS industry. It supports multiple data format conversion, scene editing and service distribution functions. Its simple operation interface and powerful functions make the conversion from Geotiff to Cesium Terrain format simple and efficient.
Operation steps
1) Open the GISBox software, click on the left to switch to the “Slicing” function, and then click the “New” button in the upper right corner to create a slicing task.
2) Click on the left side to switch to “Terrain Tiling”, then click the “+ Add File” button at the top to add our local files, and finally click “OK” to start tiling.
3) Depending on the file size, the tiling process will take a certain amount of time, please be patient.
4) After the tiling is completed, click the “Distribute” button on the left to see the services that will be automatically released after the tiling is completed.
