The HDF Group is excited to announce HDF Compass (beta), a light-weight desktop visual tool to navigate HDF5 files and other formats and resources (both local and remote). HDF Compass enables users to view datasets, attributes, and groups. Simple line, image, and contour plots are supported as well. HDF Compass is intended as a simple, focused application and conforms to the look and feel of the user’s native platform. It has a plug-in architecture that can support other file formats or remote resources. In addition to HDF5, Compass comes with plugins for ASCII Grid and OPeNDAP resources; more format plugins are anticipated. A free and open source software product, HDF Compass is cross-platform and runs on Windows (7 or later), Linux (x86, 64bit), and Mac OS X (Yosemite or later). HDF Compass is currently in its beta stage. Try it out with a one click installation at your desktop. We encourage a community development model where interested parties can submit fixes and enhancements via GitHub. If you have some knowledge of Python and interest in improving Compass, please contribute!
