Feature Description
Generate DSM (Digital Surface Model) refers to the process of calculating the height information of surface objects (including vegetation, buildings, etc.) pixel by pixel based on geometrically corrected images through a dense image matching algorithm, and then interpolating to generate a continuous raster surface model. DSM is the core foundational data for applications such as terrain analysis, flood simulation, and line-of-sight analysis. It is also the necessary geometric basis for generating orthophotos in UAV data processing workflows.
This function is only used for the Generate DSM operation within the UAV Data Processing workflow.
SuperMap ImageX Pro supports this feature starting from the 2026 version.
Function Entry
UAV Data Processing Workflow tab -> Imagery group -> Generate DSM.
Operation Instructions
| Parameter Name | Parameter Interpretation | Parameter Type |
| Ground Resolution | Sets the ground resolution of the resulting DSM, unit is m/px. The default value is 0. When the value is 0, it will be calculated automatically. | Double |
| Output Format | Sets the storage type of the result image. Provides four options: Undefined, Tiff/GeoTIFF, Erdas Image, and PCIDSK. The default is Tiff/GeoTIFF, which means using the image's original storage type for output. | FileType |
| Compression Method | Available only when Output Format is Tiff/GeoTIFF. The default is NONE. For more method introductions, please refer to Compression method. | CompressMethod |
Output Result
The resulting DSM data.
