DSM

Instructions for Use

DSM is generated based on geometrically corrected image results, which are then interpolated using a dense matching method to produce DSM data products.

Currently, only single-scene DSM data generation is supported.

SuperMap iDesktopX11i(2023) version and later support this feature.

Enable Three-Line Array Production

When the input image data comes from a three-line array sensor (including forward-looking, nadir, and rear-view images), you can choose whether to enable three-line array remote sensing imagery production.

  • Selected: Enables the three-line array remote sensing imagery production mode.
  • Not selected (default): Proceeds with image production in dual-line array mode only.
 Boolean
Dense Matching Method Dense matching method used to generate disparity maps from epipolar images. Supports two dense matching algorithms, SGM_CPU and DL_GPU, to generate point cloud datasets.
  • SGM_CPU: A semi-global dense matching algorithm based on a multi-path dynamic programming strategy. SGM considers the accuracy of matching object boundaries, robustness to illumination changes, and computational efficiency, offering significant application value.
  • DL_GPU: A dense matching method for stereo images based on deep learning.

Resolution Sets the spatial resolution of the result data. The default value is 10, and the unit is m. Double

Create Image Pyramid Checked by default. Builds pyramids for the image data using the specified resampling method to improve image zoom display rendering and performance. Boolean
Resampling Method Available when Create Image Pyramid is checked. The default is Average. For more method descriptions, please 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 stretch displayed. 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 consume additional time. Boolean

Output Result

  • Outputs DSM data to the local folder.
  • Automatically creates a DSM mosaic dataset in the OrthoData data source based on the output data.
