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
