Analiza višin poplavne vode v Ljubljani in na ljubljanskem barju ; Analysis of the flood in Ljubljana and on the ljubljana moor

Po poplavah, ki so prizadele Slovenijo v septembru 2010, je Inštitut za vode Republike Slovenije z GNSSvišinomerstvom določil višino geodetskih točk, ki so bile uporabljene za določitev višine poplavne vode na Ljubljanskem barju in v Ljubljani. Višine točk, določene z GNSS-višinomerstvom, smo kontrolirali s trigonometričnim višinomerstvom, z navezavo na reperje mestne nivelmanske mreže Ljubljana. Analizirana je natančnost določitve višin točk in določena razlika med višinami točk, ki so bile določene z GNSS- oziroma trigonometričnim višinomerstvom ; After the floods that hit Slovenia in September 2010, the Institute for Water of the Republic of Slovenia measured the heights of geodetic points (with the GNSS levelling method) used to determine the height of flood water on the Ljubljana moor and Ljubljana. The heights of these points were controlled by trigonometric levelling with connections to the benchmarks of the city levelling network of Ljubljana. An analysis of the accuracy of determining the heights of the points and the differences between the heights of the points, which were determined by GNSS and trigonometric levelling, are presented
