MultiSpec: Remote Sensing Software Since 1988

MultiSpec (engineering.purdue.edu/~biehl/MultiSpec/) is a processing system for interactively analyzing Earth observational multispectral image data such as that produced by the Landsat series of Earth satellites and hyperspectral image data from current and future airborne and spaceborne systems such as AVIRIS. The objectives of the MultiSpec project, begun in 1988, were to facilitate student classroom learning as well as graduate student research. MultiSpec was used as an aide to export the results of research into devising good methods for analyzing multispectral and hyperspectral image data. It has also found significant use in other applications such as multiband medical imagery and in K-12 and university level educational activities. Based on Google Analytics, the MultiSpec application and tutorials were downloaded over 10,000 times by users in over 100 countries during the past year. MultiSpec is available on MacOS, Windows platforms and as a web enabled tool based on a Linux platform. The source for MultiSpec is also available on github. This webinar will review the history of MultiSpec and its current capabilities.

Presenter: Larry L. Biehl was a research engineer with Purdue University's Laboratory for Application of Remote Sensing (LARS) from 1974-1985 and 1988-2004. He participated in Skylab, Landsat MSS and Landsat Thematic Mapper research, and had major responsibilities in NASA-sponsored field research programs including field spectral data acquisition and calibration procedures, data preprocessing and software development. He managed the antenna, computers and image data for the Purdue Terrestrial Observatory from 2004 to his retirement in 2020 from the Scientific Solutions Group in Purdue’s ITaP Research Computing. He helped initiate the IndianaView consortium (www.indianaview.org), with Dr. Gilbert Rochon and was the director of IndianaView until his retirement. He was very involved with the parent consortium, AmeriaView as a member of the Board of Directors and was the chair of the Education Committee. His professional contributions include the development of a software program, titled MultiSpec, which is used for remote sensing analyses using pattern recognition techniques by undergraduates, graduate students, government, commercial institutions and K-12 on personal computers running the Mac OS or Windows operating systems and more recently also as a web-enabled application on mygeohub.org as part of a NSF funded project.
