An ortho mapping workspace is an ArcGIS Pro subproject that is dedicated to ortho mapping workflows. It is a container within an ArcGIS Pro project folder that binds together all the resources and derived files (artifacts) that belong to a single image collection in one ortho mapping task. In particular, it contains an image collection to be adjusted, which is managed using the mosaic dataset data model, the generated ortho mapping products, internal files used in the adjustment process, and necessary information that manages the workspace.
You can copy, delete, and rename an ortho mapping workspace. You can have more than one ortho mapping workspace within a project, where each workspace opens its own map view. It is recommended that you use one project for each ortho mapping task. You can use multiple ortho mapping workspaces to manage the different versions of your ortho mapping tasks.
You can create an ortho mapping workspace from drone imagery, satellite imagery (with a Rational Polynomial Coefficient [RPC] camera model), digital aerial imagery, scanned aerial imagery, or an existing mosaic dataset. The type of ortho mapping workspace defines the algorithms that are used to process that type of images. You will need to choose the corresponding type when you create an ortho mapping workspace for your data. The Ortho Mapping wizard on the Imagery tab allows you to create an ortho mapping workspace from a collection of images or an existing mosaic dataset, and it also allows you to import or add from an existing ortho mapping workspace.
Create an ortho mapping workspace
There are several types of ortho mapping workspaces that can be created for your image data:
To learn about adjusting your imagery, see Block adjustment.
Create an ortho mapping workspace from an existing mosaic dataset
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.
- Click Finish.
