If you have an existing mosaic dataset, you can improve it by taking advantage of ortho mapping capabilities. This is done by creating an Ortho mapping workspace from an existing mosaic dataset.
The following are examples of use cases that can benefit from this workflow:
- You want to create a mosaic dataset from multiple satellite raster types and block adjust images of mixed satellite types with Ortho mapping tools.
- You have a mosaic dataset that has been block adjusted, and you want to use Ortho mapping tools to edit GCPs, refine your adjustment, and generate products.
- You have a collection of block-adjusted images, and you want to use Ortho mapping tools to generate an orthomosaic.
To create an Ortho mapping workspace from an existing mosaic dataset, complete the following steps:
- On the Imagery tab, click New Workspace.
- On the Workspace Configuration page, type a name for your workspace.
- Use the Workspace Type drop-down arrow to choose Ortho Mapping.
- Use the Sensor Data Type drop-down arrow to choose a sensor used in the existing mosaic dataset.
- Optionally, set the Parallel Processing Factor value of the workspace. The default value of 50% means that half of the total CPU cores will be used to support Ortho mapping processing.
- Check the Import and use existing image collection check box, and click Next
- Set your mosaic dataset to be the input for Image Collection
Note:
If the mosaic dataset has already been adjusted, check the Is adjusted collection check box.
If the adjusted mosaic dataset has the corresponding processing data, define the optional inputs: Control Points, Solution Points, Solution Table, and Solution DSM. These can be left blank, but certain operations will not be available, such as generating the Adjustment Report, performing a block adjustment, or Interpolate DEM from solution points using the DEMs wizard.
- Click Finish.
