| Summary : GeoHashTree for Point Cloud Data library
|
Description :
This package provides the GeoHashTree for Point Cloud Data library
A file format and library for storing and rapidly accessing point cloud data,
in particular LIDAR data.
GeoHashTree organizes points into a tree structure for fast spatial access.
The tree structure itself encodes the significant bits of at each node, so
child nodes can omit them. The result is a smaller file than if all the
points were stored with full precision. Each node includes statistical
information about the children below (e.g. average/median Z value) permitting
fast overview generation. Additional attributes are attached to the tree at
parent nodes, below which all children share the attribute value. This reduces
duplicate data storage further.
The advantage of a GeoHashTree file over a LAS file is fast access and filtering,
since the tree encodes useful information at each node to speed searches over
the full set of points in the file. LASZ zipped files can be smaller, but will
be less efficient at overviews, searching and sub-setting. GHT is a good working
format for applications that will be filtering and querying large sets of LIDAR data.
