DTclassifier – classification using decision trees without leaving QGIS

DTclassifier (Decision Tree classifier) — is a plugin that allows to classify raster data or perform change detection in QGIS.

Main plugin features:

• streamlined integrated approach — perform all operations in QGIS
• first use of computer vision library OpenCV in QGIS
• non-parametric classification algorithm — decision trees.

Main functionality:

• supports all basic geometry types (points, lines, polygons) in training datasets
• ability to use multiple training layers of different types
• support for multiple input rasters (changes detection)
• large rasters support
• results filtering and smoothing
• high speed classification
