Best method for tiling data, per size limitation

Post by Jonny5isAlive » Wed Jul 03, 2019 7:22 pm

Hello-

We have a client who would like to have scan data tiled, such that each tile is no larger than 4GB. Does anyone have ideas on the best method to achieve this? Is there an automated solution?

Thanks!

We have a good range of tiling options in SCC as shown in the video below. The 4GB limit is dependent on your final output format, e.g. at 4GB PTS file would probably be about 0.5GB - 1GB of LAZ. Tiling strategy also depends on type of job, so for a linear job like a road or rail you might tile by distance (e.g. every 5KM) whereas for a building you might want to tile by floor, or for another job tile by grids, 3d volumes, or user defined polygons. In SCC we also allow overlapping tiles, so if you have a specific area of interest you can make a tile out of that even though the same points exist in other tiles.

If this is a one off job, you can get a free 30 day trial of SCC that might cover your needs, same goes for FME. LASTools will also probaby do this and offer something similar. You're paying a premium here for any commercial package because what you're looking to do will amount to a tiny percentage of what you're actually buying.

For free, you might well be able script up something in PDAL or CloudCompare to do this too, haven't used either so can't comment further.
