The second band would be 'D:\temp\test.img\Layer2'. For example, my multi-band raster is 'D:\temp\test.img' (or r'D: emp est.img' or 'D:/temp/test.img'). Under 3 band data source, enter the number for each band to provide the red, green, and blue display values. 08-18-2011 01:02 PM In a python script using arcpy, to select a single band from a multi-band raster, just append '\LayerX' onto the path name.Click the Customize menu and click ArcMap Options.

Raster datasets that you can add to your map. A raster product contains templates for one or more derived Each raster product is represented by a unique icon. ASTER can collect data in 14 spectral bands from the visible to the. Raster products do not follow the default band combinations set on the Options dialog box. You can also upload your own raster data or vector data for private use or sharing. Setting this default display option is the same for ArcMap, ArcCatalog, ArcScene, and ArcGlobe. Or if you prefer to see a particular band combination when using data with more than 3 bands, you could specify 6,4,3 or 4,3,2 for the default R,G,B combination. For example, depending on the data you use most often, you may specify that bands 3,2,1 be used for the R,G,B rather than 1,2,3. You can specify a different set of defaults, mapping bands to R,G,B display values for datasets with three bands and those with four or more bands. From the Raster tab on the Options dialog box, you can assign a band to each red, green, and blue (R,G,B) display value. Attached is the setup I used in Raster Calculator. When a raster dataset has more than three bands, only three can be combined in the display at one time. No filenames too long (over 8 characters) or beginning with a number, no spaces in the file names or directory paths, no putting output into a geodatabase, so no permission issues. Select Raster Calculator from the Spatial Analyst dropdown list. Set the Analysis Extent dropdown list to Union of Inputs and click OK. Use multiple Spatial Analyst tools in a single expression. Apply Spatial Analyst operators on three or more inputs in a single expression. Support the use of variables in Map Algebra when in ModelBuilder. Select Options from the Spatial Analyst dropdown menu. The Raster Calculator tool is designed to offer the following benefits: Implement single-line algebraic expressions. When you preview a multiband raster dataset, three of its bands are combined to form a composite image in which each band supplies either the red, green, or blue display value. Add all of the rasters to combine into the current document. Setting the default bands to display multiband rastersĪ raster dataset with multiple bands can be displayed using either one band or three bands.
