Introduction to EARDAS IMAGINE

Bingqing Liang, Mansfield University of Pennsylvania


This exercise is designed to introduce students 1) how to prepare an image for Chemung County, Elmira, NY using one Landsat scene downloaded from USGS Global Visualization Viewer (; and 2) how to display and acquire basic image information with Erdas Imagine.


Type and level of course
This lab is used for a entry level remote sensing course and it is required for the Mapping Technology program in the department.

Geoscience background assumed in this assignment
No geoscience background is needed for this lab.

GIS/remote sensing skills/background assumed in this assignment
No remote sensing skills is needed for this lab.

Software required for this assignment/activity:
Erdas Imagine 9.3

Time required for students to complete the assignment:
3 hours


GIS/remote sensing techniques students learn in this assignment
Students will learn basic remote sensing skills with Erdas Imagine software including data import to the software, image display, image information display, image layer stacking, and image subset creation.

Other content/concepts goals for this activity
Students will learn basic steps to process the Landsat image data downloaded from the Internet including data extraction, data import to the software, and image layer stacking. Through this, students will also get an in-dept understanding of the "multispectral bands" concept of remote sensing.

Higher order thinking skills goals for this activity
No such higher order thinking skills goals are involved in this lab.

Description of the activity/assignment

In this lab, students receive data downloaded from the Internet covering a study area where all students are very familiar with. Their task is to use this data to learn the most basic image analysis skills with Erdas Imagine software such as data extraction, data import to the software, image layer stacking, and image subset creation. This lab can be used for future reference whenever students need to work on the Landsat images.

Determining whether students have met the goals

There are two ways for the evaluation: first, students need to answer questions listed in the lab; and second, students need to complete similar task in later labs where no detailed instructions are offered.
