IMPORTANT: When you close ERDAS, you will be asked if you want to print the Log File. You can play with the contrast to make the visual that you like. You'll need to contrast stretch the resulting image. img file with all your clipped images included.ĥ. Click EDIT and ADD IMAGE or use the button. Click the DATA PREP button, and select MOSAIC IMAGEĢ. Once you have all your clipped images, you will want to put them back together for your unsupervised classification. NOW here is one method to ( MOSAIC) multiple Images (individual blocks) together. REPEAT those steps until you have the subsets you wish to work with. img file that contains the area, layers, and data type you selected. Fill out the options selecting the image input and output, and click on FROM INQUIRE BOX button. Click the DATAPREP button, and select SUBSET IMAGEĦ. Move the box and enlarge it to include the area you want to clipĥ. Open the 'pnw98_bbg.img' file from the folder.Ĥ. In the Viewer window go to File -> Open -> Raster Layer. Open ERDAS IMAGINE from your desktop by going to Start -> Programs -> ERDAS IMAGINEĢ. The method that I have used and found to work the fastest is the following. ArcGIS Enterprise 10.8.There are multiple ways to clip ( SUBSET) an image, many of them use the subset command.Obtaining various logs for your Enterprise GIS.Shapefiles vs FGDB Feature Classes - The differences and the benefits of using Feature Classes.FAQ: How do I generate an authentication token in ArcGIS Online for accessing secured resources?.

Spatial Join’s hidden trick or how to transfer attribute values in a One to Many relationship.IMAGINE Advantage gives GIS professionals, image. No change yet? Make sure to deactivate your original raster layers underneath if you have them in ArcMap.Įnter your email address to follow this blog and receive notifications of new posts by email. IMAGINE Essentials to offer more advanced and precise mapping, point cloud, and image processing capabilities. The whites that are above 250 for example. The mosaic dataset simply acts as a reference to your images to spatially index them with pyramids for processing and any queries or conditions (like the reclassification of RGB values > 250 for example) you may want to add to them during display.Ģ) Create a new Mosaic Dataset: Right click on the geodatabase, New > Mosaic Dataset and enter your parameters, using your image’s coordinate system (with Import) and making sure to use the pixel properties from your ecw.ģ) Right click on the empty mosaic dataset and select: Add Rasters, then add your images and accept the defaults.Ĥ) Right click on the mosaic dataset and select: Build Overviews, and accept the defaults.ġ) Data Management Tools > Raster > Mosaic Dataset > Build Footprints … here you can set a ‘Maximum Data Value’ to squeeze out You will need to create a Mosaic Dataset to manage your images and be able to specify the reclassification this way. Trying to apply the Spatial Analyst > Reclass > Reclassify tool try to handle that problematic range would only result in you losing the detail in your image by simplifying the spectrum into a new classification.Ī better solution is a workflow that should make your data management more efficient as a consequence. If you had other values other than 255, 255, 255 for colours close to white (like 250 for example) and the NoData and Background colour settings were not enough to handle them, then it’s likely that that they may otherwise be rendering errors coming from the image preprocessing, perhaps from compressing the images. What do you do if you’re still seeing a background colour after applying a 255,255,255 RGB background and the NoData options as in the example below? If your raster data has a background, border, or other NoData values, you can choose not to display them or choose to display them as a particular color.Īll renderers allow you to set the NoData value to a color or No Color, while the Stretched renderer allows you to identify a specific background value and display color or No Color. The outer edge will be lightened.There is a way to overcome the edge lightened problem too. Sometimes these are expressed as NoData values, although at other times they may have real values.īackgrounds and outlines can often be the result of georeferencing your raster dataset. In order to eliminate this issue you have to use seamline, Keep in mind while editing seamline try to digitized the seamline in center of common overlap area. These can include borders, backgrounds, or other data considered to not have valid values. Sometimes there are homogeneous areas in a raster dataset that you do not want to display.
