Abstract. Automated extraction of objects from remotely sensed data is an important topic of research in Computer Vision, Photogrammetry, Remote Sensing, and Geoinformation Science. In order to discuss recent developments and future trends in research in automatic object extraction and their influence on sensors and processing techniques, the well-known ISPRS workshop "Photogrammetric Image Analysis" (PIA) and the "Munich Remote Sensing Symposium" (MRSS) are held as a common event for the first time.While in the past PIA specialised on the automatic exploitation of the image content, MRSS focuses on the geometric processing of aerial and in particular of space imagery. Realising that both areas - geometry and semantics - can significantly support each other when considered together in exploitation of images and point clouds, the two events, organised under a common roof, are held at Technische Universität München (TUM) in September 2019. At the same time, they keep their identity, as the meeting is organised as two parallel workshops with common plenary sessions and common proceedings.The aim of the common event is to seek, exploit and deepen the synergies between geometry and semantics, and to give the two scientific communities the possibility to discuss with and to learn from each other. Oral sessions with time slots of 25 min give space of 5 min for discussion of each presentation. Particular attention is also given to the poster sessions, which are supported by short oral presentations of the presenter before. The joint event addresses experts from research, government, and private industry. It consists of high quality papers, and provides an international forum for discussion of leading research and technological developments as well as applications in the field. It is worth mentioning that the ISPRS Foundation, Inc. (TIF) supports the event by providing six travel grants to qualified individuals especially from developing countries and regions.Prospective authors were invited to submit either full papers or abstracts. In total, we received 114 contributions from 28 countries.Full papers (max. eight pages) underwent a rigorous double blind peer review process. We received 48 full papers for review. Most papers were reviewed by three members of the program committee, 16 papers were reviewed by four members of the program committee. In total we received 157 full paper reviews from 35 reviewers. The maximum number of full papers per reviewer was eight. Altogether 31 papers were accepted based on the reviews for publication in the “ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences” which correspond to an acceptance rate of 65%. The fact that the full papers were peer reviewed is mentioned on each paper.Papers not passing the full paper peer review process were considered in the following abstract review process. In total 83 contributions were reviewed for publication in “The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences”. Finally 42 final papers (51%) were considered for publication.
