The Image Analyst Extension extends ArcGIS Pro with advanced tools and user experiences for Image Analysts who perform:
• Image interpretation and exploitation of imagery
• Creation of information products from imagery
• Advanced feature interpretation and measurements from imagery
• Detailed data capture and measurement on stereo imagery
• Advanced raster and image analysis workflows for machine learning and feature extraction
Improved UI & Display for Imagery
- View imagery undistorted, with vectors transformed to the image
- Image coordinate system based measurement
- Improved UX for oblique imagery
Mensuration
- Sensor model based measurements based on sensor orientation from high resolution satellite imagery and oblique aerial imagery
Raster Analytics
- Workflows and tools for image classification and machine learning
- All raster functions that currently require the SA extension, will be available through the Image Analyst extension
Stereo
- Stereo visualization and data capture capabilities, enabling detailed and accurate elevations and height measurements
Ortho Mapping Workflow & 3D
- Production level photogrammetry including triangulation, block bundle adjustments, DEM extraction, and ortho rectification
- Extraction of features from point cloud data
