LASDatum error- not covered by single grid

[S Rod]

Hello,

I'm using LASTools v230202. I'm transforming LAS files using LASDATUM but get an error along tiles that on the edges of my corridor. 

I don't want to remove the edge tiles so, is there anything that I can do so that LASDatum transforms all the tiles?

ERROR: long/lat bounding box of 'D:\SharedData\WarregoHwyGDA2020\18C\check_EPSG\MR102278_AHD_C2_2019_MGA94_56_299000_7011000.las' not covered by single grid
Press any key to continue . . .

I'm using LASDatum to do a transformation;

Transforms GDA94 / MGA zone 56 data to GDA2020 MGA zone 56 using an NTv2 Grid File
Convert GDA94_MGA zone 56 to GDA2020_MGA zone 56
conversion grid from 'GRS80' to 'GRS80' has 1101 x 1481 = 1630581 shift vectors
conversion grid from 'GRS80' to 'GRS80' has 801 x 2031 = 1626831 shift vectors
conversion grid from 'GRS80' to 'GRS80' has 881 x 1201 = 1058081 shift vectors
conversion grid from 'GRS80' to 'GRS80' has 881 x 811 = 714491 shift vectors
conversion grid from 'GRS80' to 'GRS80' has 441 x 361 = 159201 shift vectors

My suggestion is to use GDAL with gdalbuildvrt to form a VRT of the grids needed and then gdal_translate to make a NTv2 grid that covers the area you want. You could probably do it in one step with gdalwarp, but I'd have to think through the possible resampling implications.

Hi Rodriguez,

do you think this is a LAStools issue or does your grid just don't cover the edges of your data?
So the thing you can do: Get a grid covering your whole data.

Best regards,

Hello Jochen, I've checked the grid and the tiles are about 120km inside the zone (EPSG7856). LASDatum works on about 975 tiles, but not on these 12 tiles.

Hi Soledad,
we just released 240621 with a new lasdatum64.

We are now able to process LAZ files covering more than 1 grid in a *.gsb file.

The problem at the 12 files was that they cover more than one (sub)grid in your *.gsb file.
Therfore you got the error
    ERROR: long/lat bounding box of 'file.laz' not covered by single grid.

Now we output this situation just as warning, to inform you, that we use different grids for processing.
Then we switch the grid dynamic and continue with the other grid.
 
Please check if the new version of lasdatum64 works with all your files.

Best regards,

Jochen @rapidlasso
