GRIB files and time zones

An incomprehensible malfunction occurred recently for a Weather4D user, sailing in a “lost hole” on the edge of the Indian Ocean, namely the Cocos Islands, challenged me to the point of getting lost in conjectures. A GFS file due ten days ago categorically refused to be displayed in the application with the date, damn !

This unfortunate sailor - for which I would like to thank him - forced me to make a determined search for the cause of the problem.. After much procrastination, explorations of settings that may be faulty, since no other user had reported such a problem to us, the light finally came out ! Read more …

Weather4D R&N and distance calculations

Posted onOne comment

Since the arrival of ARM-based Mac (M1… M3…) and the system macOS 11 Big Sur, Weather4D Routing & Navigation works natively on our favorite computers (¹). But this happy event did not go, since then, without some small restrictions. The most annoying for users was, until this day, loss of distance calculation. This is carried out on touch devices by a two-finger long press, no function allowed the translation of this gesture on Mac. The mouse only has one pointer, not two ! Read more …
