[pdal] tindex creating empty geometry column

[Adam Steer]

I’m making tile indexes for a set of LAS tiles, and getting no geometry column:

# pdal tindex act_8ppm_index4326.sqlite "LAS/AHD/*.las" -f "SQLite" --lyr_name "pdal" --t_srs "EPSG:4326" —fast_boundary

# sqlite3 act_8ppm_index4326.sqlite

sqlite> PRAGMA table_info(pdal);
0|OGC_FID|INTEGER|0||1
1|GEOMETRY|BLOB|0||0
2|location|VARCHAR(254)|0||0
3|srs|VARCHAR(254)|0||0
4|modified|TIMESTAMP|0||0
5|created|TIMESTAMP|0||0

sqlite> select * from pdal;
34||/mnt/pointcloud/act_all/8ppm/LAS/AHD/ACT2015_8ppm-C3-AHD_6886100_55_0002_0002.las|EPSG:4326|2016-11-25T01:08:31|2017-02-07T00:02:54

…

…here, the second column GEOMETRY is empty - it should contain a blob of geometry data.

Where have I gone astray?

On this topic - do hooks exist in the tindex system to extract these data (tile boundaries) from a postGIS store?

Thanks
