Navigate to where you saved the mosaic and select Open to view the mosaic image.ħ:03 Thank you for watching this eTraining module from Hexagon Geospatial. Right click and select Open Raster Layer. Under the ERDAS IMAGINE ribbon select Home. When the Mosaic Job State reads done, click Close to complete the process. Click the Output Options tab and enable the Stats Ignore Value checkbox. In the Mosaic Tool menu, select Run Mosaic. You can now see the outline that defines the extent of the output image. From the toolbar, click on the Display Output Area Boundaries button. Press OK in the Output Image Options dialog.ĥ:46 40. Select Viewer as the AOI Source and then click OK. In the Output Image Options dialog, change the Method to User-defined AOI.
From the Mosaic Pro toolbar, click the Set Output Options icon.
Now return to the MosaicPro workspace.ĥ:20 35. Create an AOI polygon around the housing development. Activate the IMAGINE workspace and from the IMAGINE Ribbon, open the Drawing tab.

You can save time by confirming the preview results before running the full mosaic project. If you’re unhappy with the results of the preview, make changes to the project and repreview. Select Process > Preview Mosaic for Window.Ģ9. Draw a box over a small area where the images overlap. Select the Mosaic Preview icon from the toolbar. Click OK.Ĥ:07 Before running the mosaic you may want to preview the output. Enable the Feathering radio button and change the Distance to 50. This button is used to set the function used to calculate the digital number for the pixels within the overlapped area. From the toolbar, select the Set Seamline Function icon. This will create a more crisp final product. Here’s a tip: Try to run the seamlines along natural barriers in the image. The side of the seamline from which the polygon originated will increase in size when the polygon is completed. To edit, digitize a polygon around the seamline. In the next step, edit the seamline to hide it in naturally occurring features within the image. Click the Weighted Seamline radio button and then click OK.ģ:03 The seamlines that are automatically created display in the workspace. Select the Automatically Generate Seamlines icon. Make sure the the Display Seam Polygons button is toggled on. Enable the Use Histogram Matching and Use Illumination Equalizing checkbox, then click OK. This will create a smoother transition from one image to the next. Next, select the Color Correction options to modify the image histograms. From the toolbar along the top, click Show Images to display all of the images in the workspace.Ģ:18 Notice that the two images have different color contrasts and it is obvious where one image ends and the other begins. Under the Vis cell, place a checkmark by both of the images. Select OK, then OK in the Add Images dialog. Since the second image does not have a background, deselect Crop Area. Repeat the previous steps to add the second image. Click OK in the Add Images dialog.Ĭreate a Mosaic using ERDAS IMAGINE MosaicProġ:41 Once the first image is added and the edges look correct, add the second image. This will eliminate unnecessary fiducial maks on the edges. Add a check mark in front of Crop Area and change it to 20%. Click the Set button and make sure the Boundry Search Type is set to Corners. Since the image has a background, select the Image Area Options tab and enable the Compute Active Area radio button. If necessary, navigate to the directory that contains the first image, select it but don’t click OK.ġ:17 5. From the MosaicPro toolbar, select Add Images. From the Raster tab, select Geometry group > Mosaic > Mosaic Pro. Once opened, from the View group on the Home tab select the Swipe tool to easily see where the two images overlap.
These are the images that will be used in the mosaic.
