You are right that the SLAM dead reckoning trajectory will drift.

We are developing a mapping back-end where we register trajectories to consumer-grade GPS data, performing loop closure, and then doing a batch ICP-like optimization over multiple drives. This mostly eliminates drift as GPS, noisy as it may be, is mostly zero-mean over large areas.

Moving objects are mostly removed or ignored.

We are primarily interested in mapping urban environments for now. The SLAM does not work very well in a featureless corn field.

Are you planning on integrating these SLAM features into an API available from the device somehow? The spec sheet only mentions point cloud outputs right now.
The lidar device is not capable of running SLAM yet. We run SLAM on a computer with an Intel Core i7 processor and currently have not open sourced the algorithm.
