The last reason is that there are companies such as Vaisala - Siemens (2011 - disconnected from Siemens, just Vaisala alone), that deal with measuring of the impact location, type, polarity and intensity of lightning, also own an extensive databases of past years, and certainly will not be a problem for them (if interested) to trace required data. By the way, their data are often very accurate, even though they indicated a measurement error as a circle diameter round 180 m, frequently are much more accurate, even less than 10m.
sababu ya mwisho ni kwamba kuna makampuni kama vile Microsoft Vaisala - Siemens (2011 - imetenganishwa kutoka Siemens, tu Vaisala peke yake), Kwamba kukabiliana na kupima athari ya eneo, polarity aina, na ukali wa umeme, pia mwenyewe Kina database ya miaka ya nyuma, na hakika haitakuwa tatizo kwa Them (kama nia) kwamba required kuwaeleza data.
