What Is the Clip Tool?
The Clip Tool cuts out an input layer to a defined feature boundary. Like a cookie-cutter, the output is a new clipped output.
The clipping layer must be a polygon. But the input layer can be points, lines, or polygons.
The Clip Tool and Intersect Tool achieve the same results. But the main difference from the Intersect Tool is how it only retains the attributes from the input layer.
Whereas, the Intersect Tool preserves attributes from both tables input tables.
The Clip Tool is not just for vector
You can also clip raster data, using a polygon, graphic, or even a data frame.
If you need help, we have a tutorial on how to clip rasters with two different techniques.
Some of the advantages are:
- Save time by working with a subset of data.
- Perform area and summary statistics to your area of interest.
- Improves cartographic output by clipping imagery to a specific extent.
Common errors and troubleshooting
It’s always a good idea to visually spot-check a few areas after running the Clip Tool.
If your output isn’t what you expected, these are some of the common errors and how to fix them.
Missing Output – If data is missing in the output, it’s often because you selected a record selected before running the process. In this case, you will have to unselect the data and run it again.
Same Projection – When the output is shifted, this can occur from having datasets in two different protections. Try projecting your data, and running the tool again.
Repair Geometry – If no records are in the output, you can try to repair the geometry beforehand. I’ve also seen even exporting to a shapefile fix this error.
We also have a range of troubleshooting specific to 999999 errors in ArcGIS, which is Esri’s generic error code.
How to run a clip in ArcGIS
In ArcGIS and ArcGIS Pro, the Clip Tool is in the Analysis Toolbox within the Extract Toolset.
When you run this tool, you need to set its inputs, clip features, and output feature class name.
In the environment settings, you can change the finer details about your geoprocessing.
How to run a clip in QGIS 3
For QGIS 3, you can find it in the Vector | Geoprocessing Tool | Clip.
In both GIS software, there are 3 entries including an input, clipping layer, and clipped output layer.
You have the option to create a temporary layer and only use the layers have selected in your map.
Now, It’s Your Turn
Clipping data is like the bread and butter of GIS tools.
It’s straightforward, and it’s probably going to bed one of the first you learn.
