São Paulo City LiDAR Point Cloud from 2017 Aerial Survey

São Paulo City Hall's 3D Digital City Map (M3DC) provides LiDAR point cloud data for the municipality. The initial data was acquired in 2017 via aerial survey, with future updates planned. The dataset is publicly accessible in the Entwine Point Tiles format, using lossless LAZ encoding.

Use Cases

• Generate 3D city models based on the full-density point cloud.
• Analyze terrain elevation and surface features for urban planning.
• Simulate flood risk or line-of-sight studies using the detailed elevation data.
• Develop machine learning models for building footprint or vegetation detection from point cloud structure.

Strengths

• Data is provided in a lossless, full-density format (LAZ encoding).
• Dataset is structured as Entwine Point Tiles, which is a standard for efficient streaming of large point clouds.
• Publicly accessible under the GPL-3.0-only license.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and total size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
