What Metadata Every Survey Deliverable Should Actually Include
A perfectly accurate survey dataset is only as useful as the information describing it. Metadata, data about the data, is what tells anyone using that dataset years later exactly how, when, and to what standard it was collected. Without it, even excellent survey data can become a liability.
Every survey dataset connects to context, standards, and provenance, much like these connected points depend on their relationships.
Essential Metadata Every Dataset Needs
Coordinate System
Exact horizontal and vertical datum used, including UTM zone or specific projection details where applicable.
Collection Date and Method
When the data was collected and which instrument or technique was used, critical for understanding data currency.
Accuracy Statement
Documented RMSE or accuracy figure, ideally backed by independent check point verification.
Processing History
What software and processing steps were applied, allowing future reprocessing or troubleshooting if needed.
4+
Essential metadata categories
Zero
Ambiguity with complete metadata
5+ years
Data lifespan with proper documentation
Standard Metadata Formats
| Format | Common Use |
|---|---|
| FGDC / ISO 19115 | International GIS metadata standards |
| Embedded EXIF (photos) | GPS coordinates and capture time in image files |
| Survey Report Cover Sheet | Human-readable summary of all key parameters |
The best time to document metadata is at the moment of collection
Reconstructing metadata retroactively, months after a survey, is unreliable and often impossible. Professional survey practice documents these details as an integral part of the field and processing workflow itself.
Every deliverable we provide includes complete metadata documentation as standard practice, ensuring your data remains usable and trustworthy for years, not just for the immediate project. Learn more about our GIS solutions.
