SFClib

What is SFClib ?

SFCLib , is An Extensible and Scale Space Filling Curve Library for nD Points cloud indexing and querying.

You can download the SFClib in : https://github.com/kwan2004/SFCLib

How does SFC code generate ?

Usually, three steps are required in the SFC code generation.

The first step is to convert the coordinates between geographic space to SFC space. To put it simple, convert the float coordinates to integer coordinates.

The second step is to generate the bit sequence from the integer coordinates using Morton curve or Hilbert curve.

The third step is to encode the final SFC code from the bit sequence, traditional integer value or new string.

What can SFClib do for you ?

SFClib is an efficient and scalable space-filling curve library for nD point cloud management:

Multi dimensions support (xyt, xyz, xyzt, xyzi, ….)
Multi SFC encoding schema (value, hashstring,….)
Multi query support and integration of different databases
Scalability for massive point datasets
Performance experiments on LiDAR point cloud, GPS trajectory data, ……
