These step-by-step tutorials are designed to help you become familiar with features and capabilities of ENVI. ENVI Classic tutorials and associated data files are available from Technical Support for customers with older versions of ENVI.
This tutorial is the first in a two-part series about preparing data for image classification. It illustrates the concept of data fusion by creating an image for classification that consists of different attributes. This can potentially improve classification accuracy. more »
This tutorial is the second in a two-part series about preparing data for image classification. It describes how to define regions of interest (ROIs) that represent truth data for supervised classification. more »
For ENVI 5.4 and later. This tutorial describes how to create a custom task using the ENVI application programming interface (API). The custom task in this tutorial creates vegetation indices from Sentinel-2A Level 1C imagery. more »
Learn how to generate point clouds from satellite stereo imagery and how to view the point clouds in the ENVI LiDAR application. You must have a license for the ENVI Photogrammetry Module to run this tutorial. more »
Learn how to create an orthorectified mosaic from two QuickBird images. You must have a license for the ENVI Photogrammetry Module to run this tutorial. more »
For ENVI 5.2. This tutorial shows how to create various burn index images from Landsat 8 imagery, using the May 2014 San Diego County wildfires as a case study. more »
For ENVI 5.2. This tutorial uses EO-1 Hyperion hyperspectral imagery to identify areas of dying conifers resulting from insect damage. You will learn how to pre-process the imagery and how to create vegetation indices that exploit specific wavelength ranges to highlight areas of stressed vegetation. more »
For ENVI 5.2. This tutorial shows how to construct a time series from nine Landsat images of Las Vegas, Nevada, each May from 1975 to 2014. You will learn how to use the Series Manager to animate the time series and to export the animation to video. more »
For ENVI 5.2. Learn how to use the Spectral Angle Mapper (SAM) and Spectral Feature Fitting (SFF) methods to compare known reference spectra of geologic minerals to image pixel spectra. more »
This tutorial demonstrates how to calibrate an AVIRIS hyperspectral image to surface reflectance and how to use FLAASH® to correct for atmospheric effects. more »
