Known Issues

This is a list of known issues, which we aim to fix in a future release.

• Water segmentation scan may in some occasions provide false positive identifications of small water patches in very oblique images.

• LOD mesh generation may fail for point clouds with a small number of points.

• When exporting a point cloud in the LAS format (version 1.2 or version 1.4) with the DERIVEDPROJCRS type of a spatial reference system, the following warning message is printed to stdout: “(writers.las Error) GDAL failure (1) PROJ: proj_as_wkt: DerivedProjectedCRS can only be exported to WKT2:2019”. Then, for LAS version 1.4 only, an exception with the following message is raised: “Couldn’t convert spatial reference to WKT version 1.”. This is due to the absence of support of the WKT2 standard in the LAS format.

• Under some circumstances, the WKT string read back from a LAS point cloud file does not match the one used to write the file. This has only been observed on Windows, for some spatial reference systems.

• When processing Catch data without LiDAR captured with Android Xiaomi hardware, the following warning message is printed to stdout repeatedly: “Warning: Ignoring XMP information encoded in the Exif data.”. It is unclear whether this has an observable effect in the data processing.

• Inputs with non-ASCII characters are not fully supported on Windows.
