【 摘 要 】

Digitalni nivelirji so zelo poenostavili delo na terenu, saj so čitanje na lati, popravki meritev in shranjevanje podatkov popolnoma avtomatizirani. Vendar tudi na te instrumente deluje niz vplivov, ki lahko povzročijo odstopanja v meritvah. To se nanaša predvsem na negativni vpliv refrakcije, ki je glavni moteči dejavnik za doseganje natančnosti preciznega nivelmana. Na podlagi strokovne analize merskih pogojev je treba spremljati vpliv refrakcije in izbrati najustreznejšo metodo dela. Zato je zelo pomembno določiti optimalno dolžino vizure, ki bo omogočala doseganje optimalnih rezultatov, hkrati pa ohranila čim večjo produktivnost dela na terenu. V tem delu je objavljeno raziskovanje vpliva dolžine vizure digitalnega nivelirja Leica DNA03 na končne rezultate merjenja nivelmanske mreže ; Digital levels significantly simplify field work with regards to automated staff reading, measurement corrections and data storage. However, these instruments are subject to a number of influences whose effects can cause errors in measurements. This especially applies to the negative influence of refraction, which is a serious limiting factor of accuracy in precise levelling. It is still necessary to rectify the effects of refraction via professional analysis of levelling conditions and then choose the best methodology of work. It is particularly important to determine the optimal line-of-sight distance, which yields quality results while keeping greater work productivity. The impact of sight distance of a Leica DNA03 digital level on the final results of levelling network was investigated and described in this article
