It is an object-based advanced feature extraction program which can be used to extract a wide range of features from digital images. It uses both spatial and spectral information to produce feature recognition algorithms behind the scenes; however the program is user-friendly and quick to learn, even for GIS novices. More information can be found [http://web.archive.org/web/20120702123517/http://www.vls-inc.com:80/feature_analyst.htm here].\n\n== Capabilities ==\n\nFeature Analyst enables feature extraction (2D and 3D) for buildings, water, vegetation, etc., through the creation of a training set and use of the machine learner. Batch classification, change detection, hierarchical learning and post-processing abilities also exist. The tutorial document (which comes with the tutorial) and the Reference Manual (which comes with the full Feature Analyst license) provide a good understanding of all of these functions.\n\n== How to Get Feature Analyst ==\n\nThe tutorial data and information set for Feature Analyst may be downloaded from the [http://web.archive.org/web/20120702123517/http://www.vls-inc.com:80/feature_analyst.htm Visual Learning Systems website]. The tutorial exposes the user to the wide range of Feature Analyst capabilities. Only pre-set images may be used with the tutorial copy.\n\nThere is a charge to obtain the full program, but often 14-day trial licenses are offered through contacting a sales representative.\n\n{{Page data\n| license = CC-BY-SA-3.0\n}}\n\n[[Category:Queens Applied Sustainability Group Lab Protocols]]"}
