If you already have an existing mosaic dataset, you can improve it by taking advantage of the ortho mapping capabilities. This is facilitated by creating an ortho mapping workspace from your existing mosaic dataset.
Examples of use cases that can benefit from this workflow are listed below:
- 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, but you want to leverage the ortho mapping tools to edit GCPs and refine your adjustment and generate products.
- You have a collection of block-adjusted images and you want to use the ortho mapping tools to generate an orthomosaic.
The steps to create an ortho mapping workspace from an existing mosaic dataset are listed below.
- 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 a type that is suitable for your existing mosaic dataset.
- Check the Import and use existing mosaic dataset check box, and click Next.
- Set your mosaic dataset to be the input for Image Collection.
If the mosaic dataset has been already 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 Quality Report and Adjustment Report Block Adjustment and Interpolate DEM from solution points using the DEMs wizard.
- Click Finish.
