    Today we corrected a significant bug in the OpenTopography point cloud access and processing system that was introduced at the OT 2.2 release two weeks ago.  The bug, which we missed in beta testing, also went unreported by users over the past two weeks despite significantly impacting data products generated by OpenTopography.  Specifically, the bug interfered with the ability to select a subset of point cloud data based on point cloud classification type (e.g. “ground only").  This means that regardless of what classification was selected by the user, the system returned all points in a selected area.  The bug affected seven out of eleven OT-hosted datasets.

    OpenTopography is happy to announce that point cloud LiDAR data for the Napa Watershed in northern California is now available.  The Napa data were collected in 2003 by the National Center for Airborne Laser Mapping (NCALM).  This was one of the first NCALM data sets and digital elevation models derived from these data have been available via the NCALM Data Distribution Center for quite some time.  However, this release of the data by OpenTopography marks the first time that the full Napa point cloud data set has been available for download.

    This week OpenTopography has also released another update to our system.  This release is largely focused on back-end data management systems that are invisible to the user.  However, OT 2.1 marks an important milestone for OpenTopography as the updates should significantly improve our ability to quickly ingest and make available new data sets.
