Creating digital aerial imagery products with ortho mapping

The ArcGIS platform provides tools and a wizard for creating products from digital aerial imagery using photogrammetric processing. This workflow focuses on using the ortho mapping capability in ArcGIS Pro Advanced.

GIS users often need to process images acquired by digital aerial cameras to create a variety of 2D products, including orthorectified imagery (which may be exported as orthomosaics), digital surface models (DSMs), digital terrain models (DTMs), and/or stereo models comprised of one or more stereo image pairs. These data products are then used for visualization or analysis and may need to be shared with colleagues or the public.

To make photogrammetric processing more user-friendly, the ortho mapping capability in ArcGIS Pro offers a workflow-focused wizard for orthorectifying digital aerial images using the sensor model and an appropriate DEM. Users can use ground control points to ensure best horizontal and vertical accuracy, and use independent check points to measure the final accuracy. The images are managed using a mosaic dataset, which may be used directly to access images that are orthorectified on-the-fly, or to view images as stereo pairs using the ArcGIS Image Analyst extension. An orthomosaic, DSM, or DTM can be created as output data products for use in ArcGIS, or if desired, any of these products can be published as web-accessible services through ArcGIS Onlineor ArcGIS Image Server.

Explore the following resources to learn more about using ortho mapping  in ArcGIS Pro to generate 2D products from digital aerial imagery. (Not sure where to start? Look for the star by Esri's most helpful resources.)

Note:

To use this workflow, you'll need ArcGIS Pro Advanced. You can publish data products to ArcGIS Online or your ArcGIS Enterprise portal. Viewing image pairs in stereo requires ArcGIS Image Analyst.
