Surveys of the Milky Way at various wavelengths have changed our view of starformation in our Galaxy considerably in recent years. In this paper we give anoverview of the GLOSTAR survey, a new survey covering large parts (145 squaredegrees) of the northern Galactic plane using the Karl G. Jansky Very LargeArray (JVLA) in the frequency range 4-8 GHz and the Effelsberg 100-m telescope.This provides for the first time a radio survey covering all angular scalesdown to 1.5 arcsecond, similar to complementary near-IR and mid-IR galacticplane surveys. We outline the main goals of the survey and give a detaileddescription of the observations and the data reduction strategy.  In our observations we covered the radio continuum in full polarization, aswell as the 6.7 GHz methanol maser line, the 4.8~GHz formaldehyde line, andseven radio recombination lines. The observations were conducted in the mostcompact D configuration of the VLA and in the more extended B configuration.This yielded spatial resolutions of 18" and 1.5" for the two configurations,respectively. We also combined the D configuration images with the Effelsberg100-m data to provide zero spacing information, and we jointly imaged the D-and B-configuration data for optimal sensitivity of the intermediate spatialranges.  Here we show selected results for the first part of the survey, covering therange of 28 deg <l<36 deg and |b|< 1 deg, including the full low-resolutioncontinuum image, examples of high-resolution images of selected sources, andthe first results from the spectral line data.
