exportRaster Syntax for DEM

[benton]

Hello,

I have upgraded my Metashape version to 1.6.

Scripts that I have been using require updating, I have been able to find some of the changes through the change log for 1.6 Python Scripting.

But I am having trouble with the following;

In 1.5 the following ran without error;

Code: [Select]

chunk.exportDem(output_path +'/DEM/'+ project_name + "_DEM_EPSG" + v_to_epsg + "_ver_" + version + ".tif",image_format=Metashape.ImageFormatTIFF, projection=v_projection)

But in 1.6 I have attempted to apply the change as follows;

Code: [Select]

chunk.exportRaster(output_path +'/DEM/'+ project_name + "_DEM_EPSG" + v_to_epsg + "_ver_" + version + ".tif",image_format=Metashape.ImageFormatTIFF, projection=v_projection, source_data=DEMdata)

But the error message returning is;

NameError: name 'DEMdata' is not defined.

The change log says the following on page 33;

source_data (DataSource) – Selects between DEM and orthomosaic.

I have attempted to use the word DEM and get same error.

Does anyone know what the syntax is?

Ben

Hello Ben,

Please check the available Metashape.DataSource options. In this case you should use Metashape.DataSource.ElevationData.

Also you may need to adjust the projection parameter, see the example here:
https://www.agisoft.com/forum/index.php?topic=11767.msg52733#msg52733

Code: [Select]

projection = Metashape.OrthoProjection()
projection.type = Metashape.OrthoProjection.Type.Planar
projection.matrix = proj #the matrix that is calculated based on markers
chunk.buildOrthomosaic(surface_data=Metashape.ModelData, blending_mode = Metashape.MosaicBlending, fill_holes = True, projection = projection)
