Image / data processing pipeline.

• Drone imagery comes in many flavors — RGB stills, thermal video, multispectral bundles, LiDAR point clouds. Each has its own processing chain.
• Per-image vs orthomosaic: you can process single frames, or stitch hundreds of overlapping frames into an orthomosaic (georeferenced, scale-uniform map).
• LiDAR needs specialized software to build a classified point cloud → DEM/DSM → GIS.
• Platforms commonly used:
  • ERDAS Imagine — classical RS heavyweight.
  • ArcGIS Pro — general-purpose GIS; handles imagery and LiDAR.
  • ArcGIS Drone2Map — specifically for UAV imagery → orthomosaic + DEM.
  • Other photogrammetry apps: Pix4D, Agisoft Metashape, WebODM.
