Python GDALwarp cut a raster with a shapefile polygon

How do you clip a raster with a shapefile in Python?

To perform the clip you:

1. Open the raster dataset that you wish to crop using xarray or rioxarray.
2. Open your shapefile as a geopandas object.
3. Crop the data using the . clip() function.

How do you clip a raster with a polygon?

Here are the steps to clip rasters using the Image Analysis toolbar in ArcGIS:

1. Enable Image Analysis Toolbar. Enable the Image Analysis Toolbar (Windows > Image Analysis).
2. Select Raster to Clip.
3. Select Polygon Boundary to Clip To.
4. Click Clip Icon.
5. Export Raster.

How do I crop raster data?

Use the crop() function to crop a raster object. Use the extract() function to extract pixels from a raster object that fall within a particular extent boundary. Use the extent() function to define an extent.

Can I clip a raster?

An existing raster or vector layer can be used as the clip extent. If you are using a feature class as the output extent, you can clip the raster by the minimum bounding rectangle of the feature class or by the polygon geometry of the features.

How do you clip a feature of a polygon?

Start an edit session from the Editor toolbar.



Using the Edit tool, select the overlaying polygon.

1. Click the Editor drop-down arrow and select Clip.
2. Leave the buffer distance set at 0.00.
3. Under When Clipping Features, select Discard the area that intersects and then click OK.
4. Delete or move the overlaying polygon.

Can we use line clipping for polygon clipping?

Line clipping against a polygon is widely used in computer graphics such as the hidden line problem. A new line-clipping algorithm against a general polygon is presented in this paper. The basic idea of this algorithm is to change the line to be clipped into a horizontal line by shearing transformation.

Can you intersect a raster with a polygon?

Summary. It is sometimes necessary to determine the areas where the attributes of a raster layer intersect a polygon layer. In studies involving multiple attributes and covering massive acres of land, the intersecting areas may provide helpful information.
 

What is polygon clipping algorithm?

The Sutherland–Hodgman algorithm is an algorithm used for clipping polygons.

Can you clip a raster to a vector?

Clipping a raster to the bounds of a vector layer is fairly simple in the EnMAP-Box, since vector layers can be interpreted as masks. Under Raster select the raster layer you want to clip, and under Mask select the vector layer.

How do you clip a shapefile?

Go to ArcToolbox – Analysis Tools – Extract – Clip. The input feature is the layer you want clipped. Clip feature is the layer that you converted from a graphic to a feature.

Can raster data be a shapefile?

A shapefile cannot contain an attribute field to hold raster datasets. In this case, you need to use a hyperlink. The following are the general steps to add a raster dataset to a field within a feature class: Add a field of type Raster to the attribute table.
