OSNI Open Data: Digital Terrain Model for Northern Ireland Sheets 151-200

OSNI's Digital Terrain Model provides a grid of regularly spaced height points for creating 3D land surface images. This download contains data for 10k sheet numbers 151-200, published under the LPS Open Government Data Licence. The dataset is a large file hosted by the Government Digital Service on the eu_open_data platform.

Use Cases

• Generate 3D visualizations of the land surface based on the described grid of height points.
• Conduct terrain analysis for environmental or engineering studies using the digital elevation data.
• Create composite landscape models by integrating this DTM with other geospatial data like orthophotographs mentioned in the description.

Strengths

• Data is provided by the official mapping agency for Northern Ireland (OSNI), suggesting authoritative sourcing.
• The description explicitly states the data can be used to provide a 3D image of the land surface when combined with other data.

Limitations

• Description metadata is limited; actual data quality, resolution, and coordinate system require manual inspection after download.
• Row count, file size, and spatial resolution are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
