new tutorial (part 2): LiDAR tiling, bare-earth extraction, and building classification

[Martin Isenburg]

Hello,

The second part of rapidlasso's three-part tutorial is now online: how to use LAStools to implement a complete end-to-end pipeline that first quality checks a newly received set of raw LiDAR flight strips, then tiles and prepares the LiDAR for subsequent exploitation, and finally generates raster and vector derivates such as DTMs, DSMs, building footprints, and contours with multi-core batch processing ...

I was told I sent the wrong link. Sorry for that. So here again:

Stay tuned for part 3 ... should be out soon as this series will be part of the course materials for my LiDAR processing workshop at the ISPRS Summer School after the Asian Conference on Remote Sensing in Bali in two weeks.

Cheers,

Thanks for the good tutorials!

Question: do you think it would be feasible to lay this pipeline out in QGIS Modeler? My experiences with the QGIS toolbox are good, including interaction with other tools. Building pipelines such as these within QGIS would be awesome!

Hello Jan,

seems like you are reading my mind. Indeed, the plan is to eventually build entire pipelines of LAStools in QGIS. What I will need, however, is to also provide tools that can operate on entire folders of files as input. I just completed such a new toolbox for ArcGIS ("LAStools Professional") and started to put together the first two LiDAR processing pipelines using the ArcGIS Model Builder ("LAStools Pipelines). This is now available as a prototype for testing in the latest release (131016). Feedback welcome ...

Martin
