Preface: Technical Commission I

Abstract. For ISPRS Technical Commission I (TC I), a remarkable number of 189 submissionsfor the 2020 Congress edition of ISPRS Annals and ISPRS Archives was received.This included both full paper and abstract submissions from all over the world.Encouraged by the success of double blind paper reviewing in preparation of the2016 Prague congress and the 2018 Karlsruhe symposium, also this time, TC Iorganized a strict peer-reviewing process. This included double-blind reviewing forfull papers as well as a two-stage evaluation of abstract submissions – first stagebased on the submitted abstracts (“conditional acceptance“), and second stage after submission of the respective final papers.

In total, we received 69 full paper submissions and 120 abstract submissions, whichindicates a nice trend towards full paper submissions compared to previous TC Ievents.

45 full papers passed the double-blind peer-review process and were accepted forpublication in the ISPRS Annals (acceptance rate 64%); usually, three or four reviewswere obtained for each paper. Abstract submissions and their respective final paperswere reviewed by a team of professionals. In total, 76 papers were accepted to theISPRS Archives.

The manuscripts in both the ISPRS Annals and Archives cover a broad range oftopics related to remote sensing platforms, technologies, systems and relatedmethods and reflect the current trends in algorithmic research and developments insensing and data acquisition methods. Noteworthy is that numerous contributionswere submitted to Intercommission WGs of TC I with TC II and TC IV, whichunderlines the increasing trend towards an integral approach to sensors, systemsand methods in photogrammetry, remote sensing and mobile mapping.
