Filter DSM
Instructions for Use
Filter DSM refers to the process of filtering DSM data to remove surface features such as buildings and vegetation, resulting in DEM data.
SuperMap ImageX Pro 11i(2023) version starts to support this feature.

| DSM Filtering Algorithm |
Provides two algorithms: TSGF and UNETF, with TSGF as the default.

| Elevation Filter Value | A uniform subtraction of the elevation filter value is applied to non-flat areas. Default is 10. | Double |
| Slope Threshold | If the slope value is greater than or equal to this slope threshold, the area is considered mountainous; otherwise, it is flat. Default value is 8. | Double |
| Output Format | Uses the Output Format parameter from Set Image Path (DSM/DEM) and is not editable. | FileType |
| Compression Method | Uses the Compression Method parameter from Set Image Path (DSM/DEM) and is not editable. | CompressMethod |
| Output File Path | Uses the Processing Path parameter from Set Image Path (DSM/DEM) and is not editable. | File |
| Create Image Pyramid | Checked by default. Builds pyramids for the image data according to the specified resampling method to improve image scaling display rendering and performance. | Boolean |
| Resampling Method | Available when Create Image Pyramid is checked. Default is Average. For more methods, refer to Resampling Method. | PyramidResampleType |
| Asynchronously Create Statistics | During image browsing, the layer will be stretched based on statistical information. If the image lacks statistical information, it will be displayed using the default stretch method, and 8-bit data will not be stretched. Checked by default, meaning statistics will be created for the image in the background without affecting the process execution. If unchecked, statistics will be created while executing this tool, which may take additional time. | Boolean |
Output Result
- Outputs the filtered data.
- Automatically creates a DEM mosaic dataset in the OrthoData data source based on this data.
