Clip A Raster
- Use the CLIP command to subset a raster by entering the max/min X & Y coordinages of the area you are interested in. This results in a new rectangular image.
- ArcToolbox > Data Management Tools > Raster > Clip
- Input Raster: Load the image you want to clip
- if you use the drop-down arrow to specify a layer shown in ArcMap, only the 3 layers displayed will be processed
- if your image has more than 3 layers (ie Landsat image), do not use the drop-down arrow, instead, use the Open Fiel button and select the dataset manually
- Rectangle: Enter the minimum X and Y values that define the extent
- you can find these by moving the mouse over the image and recording the values shown in the lower-right of the screen
- Output Raster: Enter the name of the new, clipped image you will generate
- Hit OK to process
