More details can be found at https://mygeohub.org/blog/2019/09/introducing-the-fall-2019-duri-interns.
July 7, 2019 - New release of MultiSpec
A new release of MultiSpec Online includes the K Nearest Neighbor classifier, one of the simplest machine learning classifiers. A user can change the k value for nearest neighbors by holding the shift key down before selecting 'K Nearest Neighbor (KNN)' in the 'Procedure' dropdown menu in the Classify dialog box. One can threshold results by setting the minimum number of most common nearest training neighbors. For example setting the threshold to 4 will require that a pixel be assigned to a class only if there are 4 or more training pixels for that class in the k nearest neighbors. Note that the threshold has to be less than or equal to the 'k' value for the classifier. One can also create a 'KNN Values File' which is similar to a probability image file; the resulting image indicates the number of common classes for each pixel in the image.
MultiSpec Online is the online version of the freely available MultiSpec software for multispectral and hyperspectral image processing and visualization, created by Larry Biehl of Purdue University. The online version has become the most popular tool on MyGeoHub, having been used by more than 1000 users to date.
October 26, 2018 - New HydroShare Release Provides Improved Accessibility from Resource Page
The latest HydroShare release 1.15.5 now includes the ability to launch GABBs tools on MyGeoHub.org, directly from a HydroShare resource page. As proof-of-concept, the MultiSpec tool has been configured to be launchable from any geospatial raster resource uploaded to HydroShare, and will automatically load the raster resource on launch. This implementation leverages several technologies including, iRODS federation, OAuth authentication and customizable HUBzero tool launch URLs.
