A radio continuum survey at medium Galactic latitudes with the Effelsberg 100-m telescope is being carried out at a centre frequency of 1.4 GHz in total power and linear polarization. Areas up to $\pm 20\hbox{$^\circ$}$ of Galactic latitude are now being observed at a sensitivity of 15 mK $T_\mathrm{B}$ in total intensity and 8 mK $T_\mathrm{B}$ in linear polarization with an angular resolution of $9\hbox{$.\mkern-4mu^\prime$}35$. This paper describes the observing and reduction technique applied which results in absolutely calibrated maps. The methods are illustrated by examples of images from the survey.

Key words: polarization -- methods: data analysis -- techniques: polarimetric -- surveys -- galaxy: structure -- radio continuum: ISM
