![]() In image processing, this is most often done to aid in understanding the nature of the data by linking "high" resolution data with "coarse" resolution data. Geographic data my be "linked" through their common locational data and quired about their variation or differences. This means that the geo-registered image data may be considered "geographic" data. ![]() This means that when two images have been geo-registered in a common real world projection and coordinate system they therefore have both spatial information (the X,Y locations for each pixel or raster grid cell) and they have descriptive data (the value of reflected energy for a given number of wavelengths). Finally, we will learn about geo-linking image with ERDAS. Zoom in on the image a few times so that you can see each individual pixel.ġ0. As you do this, notice that the X and Y values in the table change. Use your pointer to move the cross-hairs by clicking once in the intersection of the two lines and dragging the center of the cross around. The following menu will appearĪnd white cross-hairs will appear on the image. Change back to the arrow button and click on. This part of the exercise is to illustrate the point that ***Clicking on the right mouse button gives you access to many of the functions in ERDAS*** So.if you cannot find a function in the menu or on the tool bar, try clicking once on the right mouse button.Ĥ. This command is analogous to the "Zoom to Theme Extent or Full Extent" buttons in ArcView. Click on the image with the right mouse button and choose "Fit Image to Window" from the menu that appears. On the toolbar inside the the Viewer window, click on the Zoom In button. Make sure that the file type is ".img".ģ. Open the "pnw98_bbg.img" file from the folder. In the Viewer window go to File -> Open -> Raster Layer. All available functions for ERDAS can be activated from the Menu Bar however, not all functions can be activated from the Viewer.Ģ. When ERDAS opens, a Menu Bar running across the top of the screen and a Viewer window below the Menu Bar appear. Open ERDAS IMAGINE from your desktop by going to Start -> Programs -> ERDAS IMAGINE 8.4. if you cannot find a function in the menu or on the tool bar, try clicking once on the right mouse button. This part of the exercise is to illustrate the point that *** Clicking on the right mouse button gives you access to many of the functions in ERDAS*** So. ![]() Click on the image with the right mouse button and choose " Fit Image to Window " from the menu that appears. ![]() All available functions for ERDAS can be activated from the Menu Bar however, not all functions can be activated from the Viewer. Lawrie went on to lead the remote sensing division of Esri, where he reunited with his classmate Jack Dangermond.ERDAS IMAGINE Exercise 1. After much success, the company was sold to Intergraph. They decided if red was good enough for Coke, it was good enough for Erdas. The Erdas logo was branded in red one night when Lawrie and Bruce were looking out the window of their new office to see the headquarters of Coca Cola, in downtown Atlanta. There was much discussion about the product name and the entire company (about 50 employees) weighed in on the new name. Erdas Imagine was released in approximately 1989, I believe. Data was obtained on 9 track tapes, which were delivered to users through the mail, in response to a paper form and paper check, mailed to the data provider. At the time, Erdas was a command line computer package that ran most efficiently on a PDP-11 or Microvax computer, although the software was transitioning to the DOS based personal computer, with a maximum hard drive capacity of 32 MB. Lawrie and Bruce left Harvard to found Erdas, Inc., while Jack founded Esri. Carl Stienitz, maybe the first professor to teach GIS concepts in the U.S. Both graduated from the Harvard School of Design (Landscape Architecture) under Dr. The company was started by Lawrie Jordan and Bruce Rado, two amazing individuals. At the time it was a start up company in an incubator facility on the campus of Georgia Tech University.
