![]() ![]() You can link any Views that cover the same Geographic area and reference to the same map units. You can see the change in all the values. Click cross-line press mouse left click and drag in the image. On the Home tab, click Inquire Cursor. Open an Inquire Cursor in the active View (The Inquire Cursor dialog also opens. The Inquire a cursor displayed as a cross-line to single-pixel value information.ġ. The Inquire Cursor provides detailed Geographic Information as well as a pixel, lookup table, and histogram values for individual pixels within an image. ![]() In Home Tab, to the Information group, click Metadata and select View/Edit Image Metadata. View all the Information of Raster Layer. Check into Fit to Frame check Box and click OK. Then you set Raster options, click Raster options Tab, choose Display type- True Color-( RGB). Select Open Raster Layer, Layer to Add window is appears, choose File. Right-click in map view and select Layer. You can also use the shortcut process to Add layer (ii). In the File menu > Open and select Layer (i) or Data ( Raster or Vector). Now Reset Data Directory and Output Directory, click Save and close. Use the Preference Editor to customize IMAGINE for your use.Ĭlick File button > Preferences. Preferences pane appears, expend IMAGINE Preferences, then expand User Interface, select User Interface & Session. Also add multiple 2D Views, 3D Views, and map views. In the Home Tab Window group, select Add views. Map View-A View window designed for creating cartographic-quality maps and presentation graphics, usual output to a hard-copy device.3D View-Renders 3-dimensional DEMs, raster overlays, and vector and annotation feature layers.2D View-Displays Raster, Vector, and annotation data in a 2-dimensional view window.When the job is done, push the OK button and your subset is ready to go.ERDAS IMAGINE, There are three types of Views for displaying and processing Data. įrom the Subset dialog box, select the input file and anoutput destination and file name Select Raster → Subset and chip → Create subset image. Select File → Save → AOI layer as from the viewer menu bar.Įnter the name for the AOI layer under save AOI as (the AOI extension is added automatically).Ĭreate an AOI layer that we want to subset out. Select Drawing button from the viewer menu bar.Ĭlick the Rectangle icon from insert geometry in the AOI tool palette.ĭrag and the release to draw a rectangle over the AOI. Select File → New → 2D View → AOI layer from the viewer menu bar. _ NOTE: Each viewer can display only one AOI layer at a time._ The exercise is about how to create an AOI layer that can be saved as a file and recalled for later use. The option to use a specified AOI for processing is available from many dialogs throughout ERDAS IMAGINE. ![]() Specific processes can be applied to this AOI only, which can save considerable time and disk space. These options allow to define an AOI (Area of Interest) in the image, excluding other parts of the image. By working with data that has a smaller file size it allows faster processing and display updates. At times, it makes sense to cut out a subset of this larger image to simplify analysis and focus on the portion of the scene that is of primary interest. A typical Landsat scene covers an area of about 185km by 185km.
