Copy a region

Available with Image Analyst license.

Use the Copy Region tool to copy a region from a raster layer and paste it into a different raster dataset that you want to edit. For example, you can copy an existing neighborhood to replace a neighborhood obscured by clouds. This is similar to a copy and paste operation using a block of pixels.

The workflow is as follows:

1. Start a Pixel Editor session.
2. Copy a region to a new location.
3. Save your edits.

Start a Pixel Editor session

Pixel Editor can only edit one layer at a time per map view. The contextual layer used to start the Pixel Editor session is the only layer that can be edited in that map view. To edit another layer in the map, you must first close Pixel Editor, select the other layer in the Contents pane, and reopen Pixel Editor to operate on that layer.

1. In the Contents pane, select the raster layer to edit.
2. Click the Imagery tab.
3. Click the Pixel Editor button .

Copy a region to a new location

In the Pixel Editor session, you can copy a region to a new location. In this example, you will use an existing housing development and the block of pixels on a vacant lot to visualize what the new lot will look like.

1. Zoom in to the area where you want to copy a region of data.
2. On the Pixel Editor tab, click the drop-down arrow below Region Mode, and choose New .
3. Click the drop-down arrow below Region, and choose Polygon .
4. Draw a polygon around an existing housing development. You will copy that region to the vacant lot to the northwest.

   

5. Ensure that the Source Layer drop-down list is set to the correct layer, which is the layer being edited.
6. Click the drop-down arrow below Capture, and choose Copy Region .

   If a region is not selected when you choose Copy Region, you can create a polygon region.

   A small yellow circle appears in the center of the copied polygon.

7. Click and hold the mouse button on the circle, and drag it to the new location on the map.

   

   Drag the yellow circle to move the copied region to the new location.

8. Optionally, color match or blend the region while it's in preview mode.

   Color matching and blending are only available for multispectral and panchromatic imagery.

9. When you're finished, double-click the display to accept the update.

   A copy of the selected region is pasted into the location where the vacant lot used to be.

   

Save your edits

To commit your edits back to the data source, you must save them.

1. In the Save group, click the Save button .

   To save your edits without affecting the source data, save to a new file. In the Save group, click the Save As button , and specify a location and file name for the new file.

2. Click Close Pixel Editor in the Close group when you finish editing the raster dataset.
