In the ER Mapper application, the term means GeoLink make connections between two or more images in a different window. GeoLink mode should be in the same projection system. ER Mapper provides GeoLink modes include: Window mode is the relationship of two or more different image in the display window on the windows the same extent.
Screen Mode is the relationship between the image where the image as a master, while the other image relative to him.
a. GeoLink to Window
GeoLink to window provides an easy to observe some of the images that have the same coverage area, or nearly the same at the same time in separate windows, but with the same scale.
- To provide first started, two different image data in the same projection system (eg landsat_indonesia.ecw and pangrango_001_geo.ecw)
- Open a new window by clicking the open fi twice to display two windows
- Click to load the data (Landsat indonesia.ecw) the unity window, and click to load the data (pangrango_001_geo.ecw).
- For the window to one and the second window, right-click and then click Quick Zoom | Set GeoLink to Window to create a window mode.
- Two windows are connected to each other, and the addition can be done to make GeoLink window window as much as possible.
b. GeoLink to Screen
GeoLink GeoLink to Screen is a system in which one image is displayed with a particular viewing position, while the other images will have the same position and tied with the first image window. So GeoLink to screen this will have a display as an overlay, but with separate layers for different window for each image.
- To provide first started, two different image data in the same projection system (eg landsat_indonesia.ecw and pangrango_001_geo.ecw)
- Open a new window by clicking the open fi twice to display two windows
- Click to load the data (Landsat indonesia.ecw) the unity window, and click to load the data (pangrango_001_geo.ecw).
- For the window to one and the second window, right-click and then click Quick Zoom | Set GeoLink to Screen for making screen mode.
- Two windows are connected to each other, and can be done to make GeoLink addition of window screen as much as possible.
Overlay and Algorithms
Algorithm is the basic building within ER Mapper algorithm stores all the information necessary to display the data as an image. The information stored in an algorithm includes a data source, the colors used for display, data processing steps in detail. An algorithm is a revolutionary concept that separates the data from data processing. All data integration, data processing options other files contained in the algorithm. All this is created and edited by ER Mapper, ER Mapper which contain different types of data processing algorithms.
- Please open the file that has been available (eg Landsat indonesia.ecw)
- Open the window by clicking the algorithm (RGB): RGB, so the image appears like this
- Click the button text [RGB] RGB to activate the layer file
- Click the paste to duplicate the layer so that the display becomes as shown below
- Click on the topmost layer (as shown in the figure above) then click the blue layer to loading new data, and select the file you want the dioverlay (eg pangrango_001_geo.ecw).
- Storing files in the. Alx, for example, is stored with the name citra1.alg.
- To open the algorithm, from the menu bar select File, then select Open, select the name of the algorithm are shown.
TWO IMAGE mosaic
- Open the two images in a different window so as to produce images like this
- On one of the select window, window display lights up blue. Then click the [RGB] RGB to open the display algorithm.
- Activate the text [RGB] RGB and the new window click to copy the file layer.
- Then turn on the only window, and click the [RGB] RGB to display algorithm.
- Click the paste icon to paste the previous file layer, and zoom all datasets
- Will appear as below
- Do file storage, can be in the form. ALG, res, tiff, or ECw.
Or can also use the following steps:
- Make sure the file you want to dimosaik be in one folder and have the same projection system.
- Click blur (image display and mosaic wizard) on the ER Mapper window.
- Enter any of the files that will dimosaik by clicking open the file and activate the Mosaic all files of this type and Manually set mosaic method.
- Click Next to move on.
- - Enable Cell sizes, Types of data, Number of bands, and Coordinate Systems. Then click Next to start the process.
- If you want to vary the file to be in the mosaic, mosaic type, or otherwise, click on the option that appears to repeat the process.
- Click Finish to close the dialog box.

thereon. 542 rgb sentence indicates that the algorithm file being opened is rgb542.alg. while other signs have been described previously..
