Massive point cloud data collections present unique processing challenges. The first roadblock in providing large scale point cloud web services is data organization. We will describe the techniques used in the open source Entwine library for indexing and organizing province-scale LiDAR collections for delivery as streaming web services. We will describe how the software organizes point cloud data, demonstrate its use in providing web service infrastructure, and discuss future integration possibilities of Entwine with other point cloud softwares.
