Change Mosaic Dataset

The Change Mosaic Dataset includes the following:

1. Add Image

2. Manage Mosaic Dataset .

3. Rebuild Bounds

4. Crop Display Range .

5. Balance Mosaic Dataset Colors .

6. Clear Color Balance .

Add Image

Function Description

After the Build Mosaic Dataset is complete, proceed to add the *.tif, *.tiff, *.imgImage Files from local or Cloud Storage to the current Mosaic Dataset.

Function entrance

  • Mosaic Dataset Context Menu-> Change Mosaic Dataset-> Add Image-> Add Mosaic in Workspace Manager-> Data source list Data dialog box.

Manage Mosaic Dataset

Function Description

In the Manage Mosaic Dataset, you can select an Image Dataset that does not build an Image Pyramid with one click and Create Image Pyramid for it. You can also delete the selected Dataset and Export File List.

Function entrance

  • Mosaic Dataset Context Menu-> Change Mosaic Dataset-> Manage Mosaic Dataset in Workspace Manager-> Data source list.

Rebuild Bounds

When the data in Mosaic Dataset changes, for example, some images are deleted, new images are added, and Clip Bounds exist in the image, click this function to Mosaic DatasetRebuild Bounds. See Rebuild Bounds for details.

For the application of Rebuild Bounds, see Image Map Configuration-Rebuild Layer Bounds.

Crop Display Range

Function Description

The Crop Display Range is used to set the Visible Bounds of the current Map:.

Function entrance

  • Mosaic Dataset Context Menu-> Change Mosaic Dataset-> Crop Display Range in Workspace Manager-> Data source list.

Operating instructions

  1. Find Crop Display Range through the above function entry, and provide four display methods: Select Object, Draw Rectangle, Draw Circle and Draw Polygon.
  2. Select one of the methods, draw Clip Bounds in the Map, and then click the right mouse button to end the drawing. The Mosaic Dataset in the Map will be displayed according to the drawing range.
  3. To clear Crop Display Range, click the Clear button to clear Crop Display Range.

Reassign Image Path

If the Original ImageFile Position in the Mosaic Dataset is changed or the path for generating the overview view needs to be re-assigned, the File Position path can be changed through Reassign Path.

Function entrance

  • Mosaic Dataset Context Menu-> Change Mosaic Dataset-> Re-assign Image Path in Workspace Manager-> Data source list.
Hint:
  • When you Reassign Image Data set path, it must be a full path.

Balance Mosaic Dataset Colors

Function Description

The Balance Mosaic Dataset Colors specifies a standard image as the Target Dataset to guide the color balance, and the Mosaic Dataset will be color-corrected according to the standard image, so that the images can be displayed seamlessly.

Function entrance

  • Mosaic Dataset Context Menu-> Change Mosaic Dataset-> Balance Mosaic Dataset Colors in Workspace Manager-> Data source list.

Parameter Description

Hint:
  • Variance expansion coefficient and Brightness coefficient are available only when the Color balancing method is the dodging method.
  • Standard image path: Set the path information of the standard image.
  • Color balancing method: Select a method to change the color of an image. Histogram Method and Homing Method are available. The Histogram Method is to correct the color of Mosaic Dataset according to the histogram information of the standard image; the Homogenization Method is to correct the color of Mosaic Dataset by setting the variance expansion coefficient and Brightness coefficient.
  • Variance expansion coefficient: it can be set when the uniform method is selected. When the Brightness coefficient is constant, if the variance is equal to 1, the image contrast effect is constant and consistent with the contrast effect of the Reference image; if the variance is less than 1, the contrast of the Result image decreases with the decrease of the variance value.
  • Brightness coefficient: can be set when the dodging method is selected. When the variance expansion coefficient is constant, if the pixel mean value of Reference Image is greater than pixel mean value of Original Image, the Brightness coefficient is larger. The higher the brightness of the Result image is; if the average value of the pixels of the Reference image is less than that of the Original image, the higher the Brightness coefficient is, the lower the brightness of the Result image is.

Clear Color Balance

Function Description

Clear Color Balance removes the set flat Mosaic Dataset color and restores the original color of the Mosaic Dataset.

Function entrance

  • Mosaic Dataset Context Menu-> Change Mosaic Dataset-> Clear Color Balance in Workspace Manager-> Data source list.
