Abstract [en]
This is a transcript from the witness seminar “Bildens behan-dling och utvecklingen av digital fjärranalys” (Processing the im-age and the development of digital remote sensing), held at the Swedish National Museum of Science and Technology in Stock-holm, June 14, 2017, and was led by Håkan Olsson and Johan Gärdebo. The seminar participants, who were all pioneers from the early Swedish development of digital remote sensing, de-scribed their role in various initiatives and activities for devel-opment of remote sensing related image processing from the 1970s until the late 1990s. During this period, several university groups, government agencies and companies located all over Sweden took interest in remote sensing. The Swedish Defence Research Institute (FOA) developed the first digital image analy-sis system, Piccola, in the early 1970s. Piccola, hosted as a main frame computer at Stockholm’s computer centre QZ, became a central resource for the early development of digital remote sensing in Sweden. During this early period, Professor Gunnar Hoppe at Stockholm University took a leading role for technol-ogy- and method development by chairing the National Remote Sensing Committee, providing a forum for various initiatives to meet, grant funding, and build momentum for concerted efforts. In the end of the 1970s, the Swedish Space Corporation (SSC) became the central force for development of the remote sensing infrastructure in Sweden. Piccola was replaced by a more mod-ern interactive image analysis system at SSC, the IAS system. This was part of SSC efforts to make satellite remote sensing operational. Additional parts in this effort included establish-ment of a satellite data receiving station at Esrange and later in the 1980s the establishment of the SSC’s subsidiary Satellitbild AB in Kiruna, which processed SPOT satellite data for the world market. SSC also developed the EBBA series of image analysis systems, attached to a PC, which were used by several Swedish research groups. From the late 1970s and onwards, there were a number of spin-off companies from FOA, most notably Con-text Vision and Teragon, that developed image processing hard-ware and software for uses also beyond that of geographical in-formation. These companies also sold systems to the Swedish Land Survey and SSC. Swedish organisations had a large pres-ence internationally, for example as part of development projects by consultancy firms, which also led to more operational uses of image processing. As computer capacity increased, in particular the introduction of colour graphics on standard computers, im-age processing development moved from special hardware to standard work stations and eventually personal computers and the applications that have become operational, for example in the forest sector, has been integrated with GIS applications in tailor made production-oriented systems.

Note
Vittnesseminariet ”Bildens behandling och utvecklingen av digital fjärranalys” genomför-des på Tekniska museet i Stockholm den 14 juni 2017. Seminariet arrangerades inom ramen för projektet ”50 år i rymden: Ett dokumentationsprojekt om svensk rymdverk-samhet” finansierat av Rymdstyrelsen och Vinnova med bidrag från KTH Space och SSC. Projektet leddes av Nina Wormbs och bedrevs vid Avdelningen för historiska studier av teknik, vetenskap och miljö vid KTH, i samarbete med Tekniska museet. Forskningssekreterare var Martin Emanuel och Johan Gärdebo. Vittnesseminariet spelades in med ljud och bild samt transkriberades därefter. Seminariet planerades av Johan Gärdebo och Nina Wormbs vid Avdelningen för historiska studier, KTH, tillsammans med Håkan Olsson, SLU. Redigeringen av transkriptet har skett varsamt och i syfte att öka tydlighet och läsbarhet. Vissa strykningar har gjorts. Originalinspelningen finns tillgänglig på Tekniska museet i Stockholm.
