Abstract
The Leibniz Institute for Applied Geophysics reprocessed all gravity data accessible to the institute. Governmental institutions, research institutes, and industry have collected the data for 75 years. The data have been checked and homogeneously reprocessed to obtain a highly accurate data set for Germany and neighbouring regions. From the recalculated anomalies, digital grids with different specifications were derived and a printed map of the Bouguer anomalies was published.

This report describes all steps leading to the creation of the improved dataset and the map.

chapter 1: the necessity of reprocessing is explained and a schematic outline of the work is given; the generated products are briefly introduced

chapter 2: the formulas used to calculate the individual reductions are introduced and compared with simpler solutions

chapter 3: details of the available data are presented; the entire data set comprises about 355,000 gravity stations

chapter 4: the multi-stage process of quality control is discussed; height comparisons with digital terrain models and position comparisons with aerial photographs and digitized topographic maps identify points with incorrect heights or positions; to identify erroneous gravity values and anomalies, an additional iterative cross validation was carried out

chapter 5: details regarding the recalculation of terrain reductions are provided

chapter 6: explains the procedure for gridding and subsequent mapping of the recalculated anomalies

chapter 7: as suitable geoid models are available, Bouguer anomalies can be referred to ellipsoidal heights instead of national height systems; a description of the steps involved in generating a corresponding data set is followed by a closer examination of the differences between the two versions of the map

chapter 8: contains a summary and an outlook on possible future steps to improve the nationwide knowledge of the gravitational field
