Abstract
Education and public outreach (EPO) activities related to remote sensing, space, planetary and geo-physics sciences have been developed widely in the Earth and Planetary Image Facility (EPIF) at Ben-Gurion University of the Negev, Israel. These programs aim to motivate the learning of geo-scientific and technologic disciplines. For over the past decade, the facility hosts research and outreach activities for researchers, local community, school pupils, students and educators. As software and data are neither available nor affordable, the EPIF Spec tool was created as a web-based resource to assist in initial spectral analysis as a need for researchers and students. The tool is used both in the academic courses and in the outreach education programs and enables a better understanding of the theoretical data of spectroscopy and Imaging Spectroscopy in a 'hands-on' activity. <br><br> This tool is available online and provides spectra visualization tools and basic analysis algorithms including Spectral plotting, Spectral angle mapping and Linear Unmixing. The tool enables to visualize spectral signatures from the USGS spectral library and additional spectra collected in the EPIF such as of dunes in southern Israel and from Turkmenistan. For researchers and educators, the tool allows loading collected samples locally for further analysis.
Highlights
Spectral analysis is one of the most widely used methods for data analysis in geo-sciences, oceanography, atmospheric science, astronomy and engineering

Summary
Spectral analysis is one of the most widely used methods for data analysis in geo-sciences, oceanography, atmospheric science, astronomy and engineering. A main use of spectral analysis is applied when using remote sensing data [1]. What seems trivial for researchers is found difficult to understand and implement by students. Spec tool and its main functions are outlined and demonstrated for the purpose of web-based resource sharing in educational programs and collaborative research
