ArcGIS/Clip Tool
How to get to the clip tool: Data Management Tools -> Raster -> Raster Processing -> Clip
Clip is used to cut out a piece of one feature class using one or more features in another feature class as a "cookie cutter". This tools is helpful in creating a new feature class. The clip features can be points, lines, and polygons. Attributes values from the input feature classes are also transferred to the resulting clip output. The clipped area is specified either by a rectangular shape using minimum and maximum x- and y-coordinates or by using an output file.You can save your output to BMP, GIF, GRID, IMG, JPEG, JPEG 2000, PNG, TIFF, or any geodatabase raster dataset.
Example: If you had a map and only wanted a certain area of the map, you would be able to use the clip tool to cut out that area from the map.
