exportDem

[james.herbst]

Dear Forum,
I'm having trouble upgrading various parts of my code to 1.3, in particular the exportDem and using a local coordinate system. I am pasting my bad code below and greatly appreciate any help you might offer.
With best regards,
James

Code: [Select]

for chnk in PhotoScan.app.document.chunks:
    filename = folder2 + '/' + chnk.label + '_DEM1cmPixels.tif'
    chnk.exportDem(filename, PhotoScan.RasterFormatXYZ, PhotoScan.ImageFormatTIFF, Projection=chunk.crs, , .01, .01, , -32767, False, True, False)
    print(filename)

Hello James,

What error message you are observing in the Console pane when using this code?

I see several issues that might be causing the problem:
- chunk.crs is not defined, you should use chnk.crs, if you need to export DEM in the coordinate system of the current chunk,
- the keyword for the projection argument is "projection" not "Projection",
- in the function you cannot use positional argument after using a keyword argument (projection in your case), so you'd batter use keywords for all the arguments.

Thanks Alexy, that helps quite a bit and I think I fixed it. The answer was more simple than I thought.

Code: [Select]

for chnk in PhotoScan.app.document.chunks:
    filename = folder2 + '/' + chnk.label + '_DEM1cmPixels.tif'
    chnk.exportDem(filename, write_world = True )
    print(filename)
