Generate DSM

Feature Description

Generate DSM is the process of interpolating geometrically corrected imagery through dense matching methods to produce DSM data products.

Currently supports generating single-scene DSM data only.

SuperMap ImageX Pro 11i(2023) version and later support this feature.

Parameter Description

Parameter Description Type
Dataset

Displays input image data for DSM generation (non-editable).

 DatasetMosaic
Dense Matching Method Algorithm for generating disparity maps from epipolar images. Supports SGM_CPU and DL_CPU methods for point cloud dataset generation.
  • SGM_CPU: A semi-global dense matching algorithm based on multi-path dynamic programming. SGM considers the accuracy of matching target boundaries, robustness to lighting changes, and computational efficiency, making it highly valuable for applications.
  • DL_GPU: A dense matching method for stereo images based on deep learning.
 DenseMatchingMethod
Resolution Spatial resolution of output data. Default: 10 meters. Double
Coordinate System Settings Inherits Output Coordinate System parameter from Set Image Path (DSM/DEM) (non-editable). PrjCoordSys
Output Format Inherits Output Format parameter from Set Image Path (DSM/DEM) (non-editable).
FileType
Compression Method Inherits Compression Method parameter from Set Image Path (DSM/DEM) (non-editable).
CompressMethod
RPC File Path Inherits RPC File Path parameter from Block Adjustment (non-editable).
File
Output File Path Inherits Processing Path parameter from Set Image Path (DSM/DEM) (non-editable).
File
Create Image Pyramid Enabled by default. Builds pyramids using specified resampling method to enhance display performance. Boolean
Resampling Method Available when Create Image Pyramid is checked. Default: Average. For details see Resampling Method. PyramidResampleType
Asynchronously Create Statistics Enables dynamic stretching based on statistical information during image browsing. When unchecked, statistics creation occurs during tool execution (may increase processing time). Enabled by default for background statistics generation. Boolean

Output

  • Outputs DSM data to local folder.
  • Automatically creates DSM mosaic dataset in OrthoData datasource.
