One of the Bezitopo programs reads geoid files in various formats and converts them to a common format so that the main Bezitopo program doesn't have to read many different formats. One of the input formats is the NGS format: https:// www.ngs.noaa.gov/GEOID/GEOID12B/GEOID12B_data.shtml . "The binary formats of the Unix format data files follow the IEEE Std. 754 binary format (big- endian), as they are developed in a Unix environment." To make sure that convertgeoid can read both endians, I got Alaska, Guam, and Samoa in big- endian and Hawaii, Puerto Rico, and Lower 48 in little-endian. But I haven't run the program on a big-endian machine. > Big-endian is essentially dead, with Fedora (which for years has > offered both BE and LE Power) dropping big-endian support due to both > a lack of resources and the fact that new Power based projects are LE. > > Red Hat EL 8 is LE only on Power. > > And IBM itself started the process to switch Power to being a LE only > platform due to client/vendor desires 4 years ago: > > https://www.ibm.com/developerworks/community/blogs/fe313521-2e95-46f2-817d-4 > 4a4f27eba32/entry/just_the_faqs_about_little_endian?lang=en That page states "No, there will be no effect on AIX or IBM i application environments as a result of this change." AIX on Power is big-endian. AIX is a Unix and should therefore run Bezitopo (and Quadlods and any other software I write on Linux or BSD) without change.
