Assisting Feature Extraction and Freeing GIS Analysts
Feature Analyst software is an automated feature extraction extension that enables GIS analyst to rapidly and accurately collect vector feature data from high-resolution satellite and aerial imagery. Many geospatial analysts have discovered that Feature Analyst helps them achieve more. With much of GIS implementation and management costs being attributed to staying up-to-date with the daily deluge of image data, the ability to quickly extract features from GIS data is a major necessity. Feature Analyst software was specifically created to meet this need and enable analysts to collect linear and polygonal features such as hydrologic zones, buildings, roads, vegetation, and land-use.

Why is Feature Analyst Software so Effective?
Feature Analyst software utilizes the spatial context as well as the spectral and pattern information within the image. The user selects training sites that represents the desired feature, then chooses a template that examines the spatial context of the target pixels within the training sites. Spatial context evaluates not only the target pixels, but the surrounding pixels to learn what to look for in the rest of the image.
Feature Analyst offers a selection of templates optimized for feature classes such as ground cover or man-made objects. The size of each template is adjustable and users have the option to create a template for a specific need.
The user is able to reinforce the extraction model to improve results by selecting correct and incorrect examples from the initial returned set of features. This iteration, called Hierarchical Learning, is an essential component of the Feature Analyst machine-learning process.
Works as an extension for Esri ArcGIS® or Overwatch's ELT/5500® and Global Image Viewer® (GIV) geospatial analysis software.
