3月17日的Vrijeme na radaru应用程序分析

Vrijeme na radaru ("Weather on the Radar") is an open--source app focused on the workflow of forecasting short-term weather in Slovenia, Croatia, Bosnia and Herzegovina and western Hungary. Get the source code here: https://github.com/mtopolnik/weather-radar-hr You get an auto-refreshed widget where you can see if there are any rains approaching your current location (the red dot). Tapping it takes you to the main screen with the radar imagery from two sources synchronously animated. Double-tap or pinch-zoom an animation to enter full-screen where you can zoom while the animation still runs. By using the seek bar you can seek to and hold any animation frame. Above every image/animation is an indication of its age so you don't waste your time analyzing stale images. You can adjust the animation rate and the pause before repeating. Faster animation gives you a better sense of rain's movement so you can extrapolate into the future. Slower animation is better for precise analysis. The app displays the animations published by the Croatian Meteorological and Hydrological Service and the Slovenian Environment Agency. These are the best sources, “from the horse’s mouth”, for this region. The radar images, as published by their hosting agencies, contain their creation time, but in UTC so usually you have to translate that to your timezone. The app reads these times using OCR and does the translation for you, so above each image you can see its age and timestamp.
