MultiSpec is a remote sensing analysis tool being developed on as part of the Geospatial Analysis Building Blocks (GABBs) NSF-funded and the IndianaView/AmericaView USGS-funded projects. The tool has been adapted from the desktop Macintosh and Windows versions ( MultiSpec is an image processing program to display and analyze geospatial images. The current working version on MyGeoHub, a hub dedicated to geospatial data applications, is a subset of the Macintosh and Windows desktop applications. The features include display of images in files from many different formatted files (geotiff, tif, png, hdf4, hdf5, netcdf, to name a few), handle images with one to hundreds of channels (bands), run unsupervised classification (cluster) analyses, run principal components analyses, generate new images from combinations of the channels in the original images such as vegetation indices or principal components images. Several tutorials are available that can be used as the basis for remote sensing image analysis training sessions. There is interest to use this web-based tool in some teacher training workshops in the coming months
