Fifteen years ago, The HDF Group set out to re-invent the HDF format and software suite to address two conflicting challenges. The first was to enable exceptionally scalable, extensible storage and access for every kind of scientific and engineering data. The second was to facilitate access to data stored in the HDF long into the future. This challenge(More)
Many problems for beginning programming students relate to program comprehension, that is, the ability to conceptualize the abstraction of a given algorithm with the flow of the program code. PS was developed to aid in this conceptualization process by providing the student a means to observe program execution via simulation. Program functions built into PS(More)
Executive Summary S ociety has been greatly impacted by the massive amounts of data that are now available for use. Immense streams of data are routinely collected across science, medicine, education, government, industry, social media, and entertainment. Yet our ability to efficiently and effectively use these " big data " sets is hampered by our(More)
Almost without exception, when we consider uses of computers in education we think about ways in which computers can help us do a better job of teaching those subjects we have been teaching. Seymour Papert takes a completely different approach to the use of computers in education. He purposes that the availability of low-cost computing in our culture should(More)
The volume, complexity, variability and accessibility of geospatial of digital geospatial data pose formidable challenges for the National Archives. Scientific and engineering communities faces many of the same challenges in managing large, complex digital data collections. This study examines gridded and vector geospatial data through the prism of(More)
