Drone or CCTV Image mapping

I need high-resolution images of an urban zone collected by drone and then processed with computer-vision algorithms so I can generate accurate survey and mapping outputs. The flight will focus on three feature sets in equal measure: buildings and other infrastructure, green spaces and parks, plus roads and traffic corridors.

Here’s what I am expecting:
• A short, well-planned flight operation that secures complete, overlap-friendly coverage of the target blocks.
• Post-flight processing using photogrammetry or similar techniques (e.g., Pix4D, Agisoft, OpenDroneMap) to deliver an orthomosaic, DEM/DSM and feature-layer extractions for the three categories above.
• Clean, GIS-ready files (GeoTIFF, shapefiles or GeoPackage) that I can drop straight into QGIS/ArcGIS for further analysis.

Accuracy and visual clarity are critical; please outline your proposed flight altitude, overlap percentages, and the toolchain you intend to run for stitching and classification so I can confirm it meets our local regulations and project tolerances.
