PROJECT DELIVERABLES – PHOTOGRAMMETRY DATA PACKAGE
=================================================

This ZIP archive contains geospatial and photogrammetric deliverables
generated from a high-resolution aerial data capture and processing
workflow.

All datasets are georeferenced and suitable for evaluation and use in
engineering, surveying, GIS, CAD, and 3D visualization environments.

   and dataset summaries

-------------------------------------------------
IMPORTANT NOTES
-------------------------------------------------

• All deliverables originate from the same project dataset.
• Coordinate system information is embedded where applicable and
  documented in proj.txt.
• No ground control points (GCPs) were used unless otherwise stated.
• Accuracy is based on onboard GNSS and photogrammetric reconstruction.

DISCLAIMER:
This dataset is intended for engineering analysis, planning,
volumetric measurement, and operational decision support.
It is not intended to replace licensed land surveying products
unless validated by a licensed surveyor.
