Clip

Cuts out a portion of a raster dataset, mosaic dataset, or image service layer.

1.    Input Raster

The raster dataset, mosaic dataset, or image service that you want to clip.

2.    Output Extent (optional)

A raster dataset or feature class to use as the extent. The clip output includes any pixels that intersect the minimum bounding rectangle.

If a feature class is used as the output extent and you want to clip the raster based on the polygon features, check Use input features for clipping geometry. If this option is used, the pixel depth of the output may be promoted. Therefore, you need to make sure that the output format can support the proper pixel depth.

3.    Rectangle

Specifies the four coordinates that define the extent of the bounding box used to clip the raster.

If the clip extent specified is not aligned with the input raster dataset, the clip tool verifies that the proper alignment is used. This may cause the output to have a slightly different extent than specified in the tool.

The Clear button resets the rectangle extent to the extent of the input raster dataset.

4.    Use Input Features for Clipping Geometry (optional)

Clips the data to the minimum bounding rectangle or to the geometry of the feature class.

  1. Unchecked—Uses the minimum bounding rectangle to clip the data.
  2. Checked—Uses the geometry of the selected feature class to clip the data. The pixel depth of the output may be increased; therefore, you need to make sure that the output format can support the proper pixel depth.

5.    Output Raster Dataset

The name, location, and format for the dataset you are creating. Make sure that it can support the necessary bit depth.

When storing the raster dataset in a file format, you need to specify the file extension:

  1. .bil—Esri BI
  2.  .bip—Esri BI
  3.  .bmp—BMP
  4.  .bsq—Esri BSQ

  10. .png—PNG
  11. .tif—TIFF
  12. .mrf—MRF
  13. .crf—CRF
  14. No extension for Esri Grid

When storing a raster dataset in a geodatabase, do not add a file extension to the name of the raster dataset.

When storing your raster dataset to a JPEG file, a JPEG 2000 file, a TIFF file, or a geodatabase, you can specify a Compression Type and Compression Quality in the geoprocessing Environments.

  • .bil - Esri BIL
  • .bip — Esri BIP
  • .bmp — BMP
  • .bsq — Esri BSQ

  • .crf - CRF

6.    NoData Value (optional)

The value for pixels to be considered as NoData.

7.    Maintain Clipping Extent (optional)

Specifies the extent to use in the clipping output.

  1. Checked—Adjusts the number of columns and rows and resamples pixels to exactly match the clipping extent specified.
  2. Unchecked—Maintains the cell alignment as the input raster and adjusts the output extent accordingly.

Create Ortho Corrected Raster Dataset

Incorporates elevation data and image metadata to accurately line up imagery.

1.    Input Raster

Select the raster dataset that you want to orthorectify. The raster must have rational polynomial coefficients (RPCs) in its metadataOutput Raster Dataset Specify a name, location and format for the dataset you are creating.When storing the raster dataset in a file format, you need to specify the file extension:

2.    Output Raster Dataset

When storing a raster dataset in a geodatabase, do not add a file extension to the name of the raster dataset.

When storing your raster dataset to a JPEG file, a JPEG 2000 file, or a geodatabase, you can specify a Compression Type and Compression Quality in the Environments.

Orthorectification Type

Use a Digital Elevation Model (DEM) or specify a value that represents the average elevation across your image.

Constant Elevation (Meters)

The constant elevation value to be used when the Orthorectification Type parameter is CONSTANT_ELEVATION.

If a DEM is used in the orthocorrection process, this value is not used.

DEM Raster (optional)

The digital elevation model raster to be used for orthorectification when the Orthorectification Type parameter is DEM

Z Factor (optional)

The scaling factor used to convert the elevation values in the DEM.

If your vertical units are in meters, the Z Factor should be set to 1. If your vertical units are in feet, the Z Factor should be set to 0.3048. If any other vertical units are used, use the Z Factor to scale the units to meters.

Z Offset (optional)

The base value to be added to the elevation value in the DEM. This could be used to offset elevation values that do not start at sea level.

Geoid (optional)

The geoid correction is required by RPCs that reference ellipsoidal heights. Most elevation datasets are referenced to sea level orthometric heights, so this correction would be required in these cases to convert to ellipsoidal heights.

Specify a name, location and format for the dataset you are creating.

8.    Geoid (optional)

The geoid correction is required by RPCs that reference ellipsoidal heights. Most elevation datasets are referenced to sea level orthometric heights, so this correction would be required in these cases to convert to ellipsoidal heights.

  1. Unchecked—No geoid correction is made. Use this option only if your DEM is already expressed in ellipsoidal heights.
  2. Checked—A geoid correction will be made to convert orthometric heights to ellipsoidal heights (based on EGM96 geoid).
