LiDAR Modeling Engine

This library is intended to ease the manipulation and processing of large lidar collections through a set of parallelized methods which interface between the datasets and a HDF5 data store.

Dependencies

ZLIB: compression library MPI: Message passing library HDF5: Hierarchical Data Format(compiled with parallel support) LibLAS: LAS data manipulation library GEOS: Geometric Topology library Proj.4: Projection transformation library GDAL: Geograpic Data Abstraction Library (compiled with external libgeotiff) LibGeoTiff: Geographic TIFF driver

Architecture

LME Datastore: Central data repository for lidar derivatives and metadata, keeps track of datasets and user access privileges. Needed to efficiently distribute processing to system.

LiDAR Region: A class which represents a geographic domain with LiDAR coverage. These regions will have administrators and user access privileges. The region will be initialized with a directory that contains LiDAR datasets.

Dataset: A LiDAR dataset (typically LAS format) which is registered for processing.

Derivative: A gridded dataset created by interpolating a subset of LiDAR points from an area. This derivative will be owned by the user that requested the data.

Workflow

  1. Initialize DataStore
  2. Register a LiDAR region
  3. Request subset
  4. Download result(or view a TMS online)
