Image Mosaic

Feature Description

Based on the mosaic line data, output the input images in Whole Map, Standard Map Sheet, or Vector Clipping mode.

Supported starting from SuperMap iDesktopX 11i(2023) version.

Function Entry

Imagery tab -> General Data Processing group -> Image Mosaic.

Parameter Description

Parameter Name Parameter Interpretation Parameter Type
Data Type

Select the source of the input image data. Two options are available: Image Files and Mosaic Dataset. Image Files is selected by default.

  
Image Files Available after selecting Image Files in Data Type. Enter the local path information in Image Path, and all images under that path will be automatically retrieved. File
Image Data Source Available after selecting Mosaic Dataset in Data Type. Specifies the datasource where the image dataset is located. Datasource
Image Data Available after selecting Mosaic Dataset in Data Type. Specifies the image dataset. DatasetMosaic
Mosaic Line Supports selecting a local *.shp file or a region dataset in *.udbx as the mosaic line data. File
Image Name Field Enter the field in the Mosaic Line region dataset that contains the image name. String
Export Directory Set the storage path for the result images. File
Resampling Method Set the method for image resampling. Three options are provided: Nearest, Bilinear, Cubic. The default is Bilinear. For more method introductions, please refer to Resampling Method. ResampleMethod
NoData Set the cell value for NoData areas in the image. The default is 0.0. Double
Output Format

Three modes are provided: Whole Map, Standard Map Sheet, Vector Clipping. The default is Whole Map.

  • Whole Map: Mosaics and outputs the entire image from the mosaic dataset.
  • Standard Map Sheet: Outputs the mosaiced image in tiles according to the specified Standard Type, Reference Scale, and Expand Range.
  • Vector Clipping: Clips the mosaiced image based on polygon object extents (Only non-parametric objects are supported). Requires setting Clip Dataset and Expand Range information.

Resolution Type

Set the spatial resolution of the result data. Two setting methods are provided: Original Resolution and Fixed Value. Original Resolution is selected by default.

  • Original Resolution: Retains the original resolution of the input images.
  • Fixed Value: Uses the input fixed value as the resolution of the output image.
 OrthoRatioType
Number of Feathered Pixels Set the number of feathered pixels at image seam lines. The default value is 0. Integer
Standard Type Available when Output Format is set to Standard Map Sheet. Used to set the type of standard map sheet. Provides National Standard and Military Standard. The default is National Standard. FrameStandardType
Scale Available when Output Format is set to Standard Map Sheet. Used to set the scale under the standard type for tiling. Provides eight basic scales. The default is 1:2000. FrameScaleType
Data Source Available when Output Format is set to Vector Clipping. Used to set the datasource where the clip dataset is located. DataSource
Dataset Available when Output Format is set to Vector Clipping. Used to set the clip dataset. DatasetVector
Expand Range Available when Output Format is set to Standard Map Sheet or Vector Clipping. Used to set the output expansion range beyond the standard map frame. The default is 100, and the unit is px. This means outputting an additional 100 pixels of image range around the standard map frame. Integer
Output Format

Set the storage type for the result image. Four options are provided: Unspecified, Tiff/GeoTIFF, Erdas Image, and PCIDSK. The default is Tiff/GeoTIFF.

If Unspecified is selected, the image will be output in its original format.

 FileType
Compression Method Set the compression method for the output image. Only available when Output Format is Tiff/GeoTIFF. The default is NONE. For more method introductions, please refer to Compression Method. CompressMethod
Create an Image Pyramid Checked by default. Builds pyramids for the original image according to the specified resampling method, thereby improving image zoom display rendering and performance. Boolean
Resampling Method The default resampling method is Average. For more method introductions, please refer to Resampling Method. PyramidResampleType
Asynchronously Create Statistics During image browsing, the layer will be stretched based on statistics information. If the image lacks statistics information, it will be displayed using the default stretch method, and 8-bit data will not be stretch displayed. Checked by default, meaning statistics will be created in the background without affecting process execution. If unchecked, statistics will be created while executing this tool, which may consume time. Boolean

Output Result

Outputs the mosaiced image data to a local folder.
