Image Mosaic

Feature Description

Based on the mosaic line data, the input image is output in the following ways: Whole Map, Standard Map Sheet, or Vector Clip.

Function Entry

Imagery tab -> General purpose data processing group -> Image mosaic.

Parameter Description

Parameter Name Parameter Interpretation Parameter Type
Data Type

Select the source of input image data. Two options are provided: Image Files and Mosaic Dataset. The default is Image Files.
Image Files Available when Data Type is set to Image Files. Enter the local path in Image Path to automatically obtain all images under that path. File
Image Data Source Available when Data Type is set to Mosaic Dataset. Specifies the datasource where the image dataset resides. Datasource
Image Data Available when Data Type is set to Mosaic Dataset. Specifies the image dataset. DatasetMosaic
Mosaic Line Supports selecting local *.shp or region dataset in *.udbx as the mosaic line data. File
Image Name Field Enter the field that stores the image name in the Mosaic Line region dataset. String
Export Directory Set the storage path for the result image. File
Resampling Method Set the resampling method for the image. Options: Nearest, Bilinear, Cubic. Default: Bilinear. For more methods, refer to Resampling Method. ResampleMethod
NoData Value Set the pixel value for the NoData area of the image. Default: 0.0. Double
Output Format

Provides three options: Whole Map, Standard Map Sheet, Vector Clip. Default: Whole Map.

  • Whole Map: Mosaics the entire image in the mosaic dataset and outputs it.
  • Standard Map Sheet: Outputs the mosaicked image in tiles based on the specified Standard Type, Reference Scale, and Expand Range.
  • Vector Clip: Clips the mosaicked image based on polygon objects (only non-parametric objects supported). Requires setting Clip Dataset and Expand Range.

Resolution Type

Set the spatial resolution of the result data. Two options: Original Resolution, Fixed Value. Default: Original Resolution.

  • Original Resolution: Retains the original resolution of the input image.
  • Fixed Value: Uses the entered fixed value as the resolution of the output image.
 OrthoRatioType
Number of Feathered Pixels Set the number of feathered pixels at the image seam. Default: 0. Integer
Standard Type Available when Output Format is set to Standard Map Sheet. Sets the type of standard map sheet. Options: National Standard and Military Standard. Default: National Standard. FrameStandardType
Scale Available when Output Format is set to Standard Map Sheet. Sets the scale under the standard map sheet type. Provides eight basic scales. Default: 1:2000. FrameScaleType
Datasource Available when Output Format is set to Vector Clip. Sets the datasource where the clip dataset resides. DataSource
Dataset Available when Output Format is set to Vector Clip. Sets the clip dataset. Each polygon object in the dataset outputs one result image file. DatasetVector
Expand Range Available when Output Format is set to Standard Map Sheet or Vector Clip. Sets the output range expanded outward based on the standard map sheet frame. Default: 100, unit: px. That is, output an additional 100 pixels of image range around the standard map sheet frame. Integer
Output Format

Set the storage type of the result image. Four options: Unset, Tiff/GeoTIFF, Erdas Image, PCIDSK. Default: Tiff/GeoTIFF.

If Unset is selected, the original image format is used for output.

 FileType
Compression Method Set the compression method for the output image. Only available when Output Format is Tiff/GeoTIFF. Default: NONE. For more methods, refer to Compression Method. CompressMethod
Create Image Pyramid Checked by default. Builds pyramids for the original image based on the specified resampling method, improving the rendering and performance when zooming in and out. Boolean
Resampling Method Default resampling method: Average. For more methods, refer to Resampling Method. PyramidResampleType
Asynchronously Create Statistics When browsing the image, it will stretch the layer based on statistics information. If the image has no statistics, it will display the image with the default stretch method and will not stretch display 8-bit data. Checked by default, meaning statistics are created for the image in the background without affecting the execution. If unchecked, statistics are created when executing this tool, which may take time. Boolean

Output Result

Output the mosaicked image data to a local folder.
