This is a False ColorД¬omposite which sends Near Infrared (NIR) Light in TM Band 4 to the Red color gun, Mid The following band/color assignments: Red 4, Green 5, Blue 3. With 512 rows and columns of raster information. This is a Landsat Thematic Mapper (TM) image that has 7 wavebands of information Now select the Raster Options tab and the following window appears. Note that you can also type the name of the file in the top box or click the popupД«elow the scroll down menu to move out of the 'geog315' sub-directory. This is the Lake Lanier region of Gainesville, Georgia. When the Open Raster Layer / Select Layer to Add box appears, select the lanier.img from the scroll down menu. Right Mouse on the View and select the Open Raster LayerДЇrom anywhere on the Erdas Application select Control + O There is more than one way to do this:ДЇrom the Erdas Application select File - Open Raster Layer Now lets open and display a raster image. Raster Layer), and using the Raster Options > Layers to Colors section to change the

To do this for an individual Layer/Image is by using the Open Raster Layer (File-Open. Using the PreferenceД®ditor is one way to alter these defaults to create a False Color Composite. That Light and Color are not the same thing helps to clarify it a bit. This may sound confusing, but remembering This portion of Light to the Red Color gun. Referring to the above FCC, the naked eyeД¬annot see infrared light and we are tricking it by sending the information contained in Possessed by the area portrayed in the image, particularly those characteristics found in Its purpose is to allow us to see any unique spectral characteristics It is called false color because electromagnetic informationДЇrom the different spectral bands (both visible and non-visible) is sent to different visible Gun/jet on a printer/monitor, Red light to the Green color gun, and Near-Infrared (NIR) It is possible (as we will see later) toД¬reate a Standard False Color Composite (FCC) by sending Green light to the Blue color Monitor will also be a combination of these colors. Spectrum are some combination of Blue, Green, and Red light. Note that all the colors you view in the visible portion of the electromagnetic These are the default satelliteД«ands from each of these systems that are assigned to your monitor/printers color Remote Sensor waveband defaults (3-6 Band images).
