## Geoprocessing tools

A large number of geoprocessing tools are provided with the Image Analyst extension. These tools are grouped into categories of related functionality in the following table and associated toolsets.

### Change Detection

The Change Detection toolset contains tools that perform change detection between raster datasets.

Tool | Description |
---|---|

Evaluates changes in pixel values over time using the Continuous Change Detection and Classification (CCDC) method and generates a change analysis raster containing the model results. | |

Evaluates changes in pixel values over time using the Landsat-based detection of trends in disturbance and recovery (LandTrendr) method and generates a change analysis raster containing the model results. | |

Calculates the absolute, relative, categorical, or spectral difference between two raster datasets. | |

Generates a raster containing pixel change information using the output change analysis raster from the Analyze Changes Using CCDC tool or the Analyze Changes Using LandTrendr tool. |

### Classification and Pattern Recognition

The Classification and Pattern Recognition tools find, identify, and quantify patterns in imagery data. You can perform classic statistical and advanced machine learning image classification and regression analysis on segmented and pixel-based raster datasets. Additional tools are provided to perform training set and classification accuracy and refinement of class maps. The following table lists the available Classification and Pattern Recognition tools and provides a brief description of each.

Tool | Description |
---|---|

Classifies a raster dataset based on an Esri classifier definition file (.ecd) and raster dataset inputs. The .ecd file contains all the information needed to perform a specific type of Esri-supported classification. The inputs to this tool must match the inputs used to generate the required .ecd file. | |

Classifies a multiband raster dataset using spectral matching techniques. The input spectral data can be provided as a point feature class or a .json file. | |

Computes a confusion matrix with errors of omission and commission and derives a kappa index of agreement, Intersection over Union (IoU), and an overall accuracy between the classified map and the reference data. | |

Computes a set of attributes associated with the segmented image. The input raster can be a single-band or 3-band, 8-bit segmented image. | |

Creates randomly sampled points for post-classification accuracy assessment. | |

Generates training samples from seed points, such as accuracy assessment points or training sample points. A typical use case is generating training samples from an existing source, such as a thematic raster or a feature class. | |

Estimates the accuracy of individual training samples. The cross validation accuracy is computed using the previously generated classification training result in an .ecd file and the training samples. Outputs include a raster dataset containing the misclassified class values and a training sample dataset with the accuracy score for each training sample. | |

Performs subpixel classification and calculates the fractional abundance of different land-cover types for individual pixels. | |

Predicts data values using the output from the Train Random Trees Regression Model tool. | |

Corrects segments or objects cut by tile boundaries during the segmentation process performed as a raster function. This tool is helpful for some regional processes, such as image segmentation, that have inconsistencies near image tile boundaries. This processing step is included in the Segment Mean Shift tool; it should only be used on a segmented image that was not created from that tool. | |
