Plotting GPS Geo cordinates with tikz/pgfplots

Question

I have a log file with thousands of geo coordinates:

flight-latitude;flight-longitude
48.7411499;11.57327366
48.7411499;11.57327366
48.7411499;11.57327271
48.7411499;11.57327175
...

I now need a way to draw a point and/or a track for every coordinate with tikz or pgfplots.

This simple example provides only a perpendicular line. It seams, that the values after the dots haven't enough impact.

\documentclass{standalone}
\usepackage{pgfplots} 
\pgfplotsset{compat = newest}

\begin{document}
\begin{tikzpicture}
    \begin{axis}[]
        \addplot [mark=o, blue] table[x=flight-latitude, y=flight-longitude, col sep=semicolon]{data/hover-data-obstacleState-5.txt};
    \end{axis}
\end{tikzpicture}
\end{document}
