Need help with specific layer (groups) export (Metashape ver. 1.7.5)

[aaltukhov]

Hello, I am trying to understand how exportShapes method works if I need to export specific layers.

I am using the following code:

chunk.exportShapes(path=current_dir + "/Polygons/All_layers/" + chunk.label +".kml", save_points=True, save_polylines=True, save_polygons=True, format=shapesformat, groups=shapelist, crs=crs, save_labels=True, save_attributes=True)

It only works if I provide a list of integer indexes I presume (it does not work with group labels or chunk.shapes.groups).
The downside is I can not figure out how to properly obtain those indexes. It does not always correspond to the order of group in chunk.shapes.groups.

Moreover, if I omit groups=shapelist all shapes will be merged and exported into one single layer.

Thank you!

Hello aaltukhov,

groups argument for exportShapes command require to input the list of int, where each element corresponds to the .key value of the shape groups (layers) that you would like to export. For example, for single shape layer export:

Code: [Select]

layer = chunk.shapes.groups[1]
chunk.exportShapes(..., groups = [layer.key], ...)
