## Image Difference

***Image Difference***

**Identifying thematic change over time**
**Identifying spectral change over time**

## Feature Extraction

***Feature Extraction***

## Automated Feature Extraction

**Use Seed Tool to identify and automatically map an area or feature of interest**
**Feature identified by defining a specific pixel value or range of pixel values**
**Once the value(s) are defined, all adjacent pixels of the feature are included in the ‘feature boundary’**
**Can be used as a signature**

## Unsupervised Classification

**User selects number of desired land cover classes or categories**** **
**Computer employs an automated clustering algorithm called ‘ISODATA’**** **
**‘****X’ number of desired categories are matched to ‘X’ most significant ‘pixel-value clusters’ in the imagery**

## Supervised Classification

**User selects number of desired land cover classes or categories**** **
**User must then identify areas of interest within the imagery corresponding to each category**** **
**Each category based on the ‘spectral signature’ of image pixels within an Area of Interest (AOI)**

## Supervised Classification

***Output confidence is expressed as probability***

## Vector

***Vector***

**IMAGINE Native Vector Features**
- Arc/Info coverage data model built-in
- Shapefile and Interchange import/export
- Display, symbolization and query
- Edit tools for creating / updating coverages
**Vector Module Features**
- Vector format import / export to coverage
- Clean and Build topology
- Table Tool
- Zonal Attributes
- Other Utilities

**Notes:**
The ERDAS Vector module is a prime example of the close collaboration of ERDAS and ESRI. No other product on the market has the ArcInfo data model built right inside. This means seamless raster to vector and vector to raster conversion. It also means simple and full featured heads up digitizing in IMAGINE.
