ساده to use نقشه based برنامه, visualizing real time full area lightning data provided by the blitzortung.org lightning location network project. The current thunderstorm situation at شما fingertips. <b>Features:</b> * realtime display of lightning data * display of historical lightning data of the last 24 hours * برای regions Europe, North & South America, Asia, Africa و Australia/جدید Zealand * lightning strike time color coded * reduced data volume و سریع response * current lightning strike time و lightning count * optional user location marker * alert function shows distance/direction of storms * background service برای alerts * پشتیبانی میکند از برای اعلانها, sound و vibration آلارم * single stroke display برای blitzortung.org participants Please visit <a href="https://www.blitzortung.org/">https://www.blitzortung.org</a> برای more information regarding the community based lightning location project. The raster display ensures a سریع عملکرد of the برنامه even if there is a very high thunderstorm activity. Blitzortung.org participants can visualize همه stroke locations individually.

The lightning warning feature can also be used بدون device location permissions as the location can also be set manually (via preferences but also via long pressing the desired position on the نقشه). You will still be able to use the warning feature بدون allowing location permissions. In order to have a more efficient data transfer با high resolution lightning data the برنامه only fetches the last 10 minutes of activity in an area of 5° x 5° rounded to five degrees. Although this data is derived from the devices location or the نقشه area currently visible it can not be used to track users. Here is why: <ol> <li> <b>Granularity</b>: A 5x5 degree area is extremely large.</li> <ul> <li> <b>Latitude</b>: 5 degrees covers approximately 555 km (345 miles).</li> <li> <b>Longitude</b>: At the equator, 5 degrees is also ~555 km. At 50° latitude (e.g., Central Europe/Canada), it is still ~355 km wide.</li> <li> This resolution is sufficient to identify a broad region (e.g., "Central Europe" or "US West Coast") but is completely insufficient to pinpoint a city, let alone a specific person or address.</li> </ul> </li> <b>Anonymization</b>: The calculation `(coordinate / scale).toInt()` effectively quantizes the location. همه users within that massive 5x5 degree square report the exact same grid index (e.g., x=2, y=10). It is impossible to distinguish between two users within that same ~300,000 km² area based solely on these coordinates. On top of that, there is no data provided which would allow to link subsequent requests coming from the same برنامه. </ol> <b>Conclusion</b>: The coordinates generated by `LocalData.update()` are too coarse برای individual tracking. They serve only to download lightning data برای the correct general region of the world.
