Ortho mapping workspace for scanned aerial imagery

Available with Advanced license.

To create an ortho mapping workspace from scanned images, you will need to prepare a frame table that defines the exterior orientations of the images, and a camera table that defines the internal orientation information of the camera. The two tables can be in a .csv format or as an ArcGIS supported table; see Frames table schema and Cameras table schema for more information.

The workflow for creating the camera and frame tables will depend on the metadata that is available with your scanned images. For example, if you already have a description of the camera model, and a table that describes the x,y,z location and omega, phi, kappa orientation of each image file, this is a relatively simple process of reformatting tabular data. If you have more limited metadata, such as no estimates for omega, phi, kappa or limited metadata regarding the camera model, then creation of the camera and frame tables in a format usable by ArcGIS may require a more manual process. Refer to the Historical Imagery Historic Imagery webpage to download tools and workflows for processing historical imagery.

Create an ortho mapping workspace from scanned aerial imagery

  1. On the Imagery tab, click New Workspace.
  2. On the Workspace Configuration page, type a name for your workspace.
  3. Use the Workspace Type drop-down arrow to choose Aerial - Scanned.
  4. Click Next.
  5. Browse to your Frame Table file.
  6. The Spatial Reference must be as same as the spatial reference of the perspective points in the frame table. If the frame table has a SRS field, it will be read automatically.
  7. Browse to your Cameras Table file.
  8. Optionally, click the Data Loader Options tab to further refine your output workspace.
    1. Use Average Elevation from the DEM option. Optionally, for a flat area you can use a Constant elevation.
      • Average Elevation from DEM—Use the average elevation from the specified DEM.
      • Constant Elevation—Use the Constant Elevation value specified.
      • DEM—Use the DEM values for each pixel. You can also specify Z Factor and Z Offset values.
    2. Optionally, you can choose to Calculate Statistics or Build Pyramids on your data before you create your workspace.
  9. Click Finish to create the workspace.

When the ortho mapping workspace is created, the image collection will be loaded in the workspace and displayed on the map. You are now ready to perform adjustments and generate ortho products.
