Description

We review recent results of a project for building a large number of comprehensive physical asteroid models from combined photo- and interferometric observations, occultation timings, and other complementary data. Photometric data form the robust and stable basis for modelling, while particularly HST/FGS-interferometry and CW radar data can add local topographic information. We have built multidatainversion procedures that can efficiently combine such complementary data. We have also studied the specific characteristics and capabilities of the sources.
