Novembre is an extensible tool for analysis and visualization of topographic and spectroscopic data. It supports the RHK, WinSPM, Nanonis, and Createc file formats, but any other format can be added via plugins. Tools are also made available through plugins, and are focused on spectroscopy manipulation.
HEALPix is a set of scientific tools implementing the Hierarchical Equal Area isoLatitude Pixelation of the sphere. As suggested in the name, this pixelation produces a subdivision of a spherical surface in which every single pixel covers the same surface area. HEALPix provides various programs and libraries in C, C++, Fortran, GDL/IDL, Java, and Python which facilitate discretization, simulation, processing, analysis, and visualization of data on the sphere up to very high resolution. It is the state-of-the-art program used in astronomy and cosmology to deal with massive full-sky data sets.
