The supermap tilt model data osgb can be transferred to DSM, the specific operation is as follows:
1. Open the supermap software, my software is supermap 8c, generate configuration files
Under the menu Tilt Photography --> Generate Configuration File
2. Configure the file to select data and projection, the interface is as follows
The source data path is the data directory of the data, the target path is the same-level directory of the data, the projection is set to the geographic coordinate system, mine is 2000 coordinates, and then enter the model reference point, the reference point coordinates need to open the metadata.xml file in the osgb data , just enter it.
Click OK.
3. Load the skewed data
Right-click on the scene in the workspace, create a new plane scene, then right-click on the normal layer to add the osgb buffer layer, load the configuration file just generated, and you will see the loaded tilt model
4. Create a new data source
Right-click on the data source under the workspace, create a new file-type data source, and save it in one place
5. Generate DSM, the 3D analysis menu item generates DSM, click OK to generate, and then export to TIFF
The DSM I generated is as follows:
Note: At the beginning, the coordinate system I chose was the projected coordinate system, with a 36-degree zone, but the coordinates still couldn't match. Later, I chose the geographic coordinate system.
