In the GIS field, Cesium has become one of the popular platforms for geographic data display with its powerful three-dimensional visualization capabilities. Geotiff, as a commonly used raster geographic data format, is widely used to store elevation, imagery and other data. How to convert Geotiff data into the Terrain format supported by Cesium has become a difficult problem for 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!

1. Why convert Geotiff to Cesium Terrain format?

Cesium's Terrain format is a data structure designed for three-dimensional terrain display. It can quickly load and present realistic terrain effects, providing users with a smooth and fluent elevation visualization experience. Although Geotiff has rich spatial information, it is not directly supported by Cesium's Terrain engine, so it needs to be converted to Terrain format before it can be loaded and displayed in Cesium.

1. Use GISBox for Geotiff to Terrain conversion GISBox is a free toolbox designed for the GIS industry, supporting multiple data format conversions, scene editing, and service distribution functions. Its simple operation interface and powerful functions make the conversion of Geotiff to Cesium Terrain format simple and efficient.

Operation steps
1) Open the GISBox software, click on the left to switch to the "Tiling" function, and then click the "New" button on the upper right to create a tiling task.

2) Click on the left to switch to "Terrain tiling", then click the "+ Add File" button on the top to add our local files, and finally click "OK" to start tiling.

3) The tiling process takes a certain amount of time depending on the file size, please wait patiently.

4) After tiling is completed, click the "Distribute" button on the left to see the service automatically published after tiling is completed.

5) Click the "Folder" button on the right to view the converted file.

6) Click the "Copy" button on the right of "Service Address" to quickly copy the service address.

7) Finally, apply the service address in GISBox to Cesium.
