LiDAR Point Cloud and Terrain Models for Brazilian Forest Research

Five forested areas in Paragominas, Para, Brazil, are covered by this dataset, which provides raw LiDAR point cloud data and derived Digital Terrain Models (DTMs). Data collection spans the years 2012, 2013, and 2014 across specific sites, including Fazenda Cauaxi and Fazenda Andiroba. The dataset is provided by the National Aeronautics and Space Administration (NASA) and includes shapefiles delineating the LiDAR coverage areas.

Use Cases

• Forest canopy height and structure analysis using LiDAR point cloud intensity and return data.
• Digital Terrain Model (DTM) generation for hydrological and topographic studies in forested landscapes.
• Monitoring reforestation or land cover change over time across the 2012-2014 period.
• Spatial analysis of forest coverage using the provided boundary shapefiles.

Strengths

• Provides multi-year temporal coverage from 2012 to 2014 for longitudinal analysis.
• Includes both raw sensor data (LiDAR point clouds) and processed derivatives (DTMs) for flexibility.
• Covers five distinct forested areas in Brazil, offering spatial variety for regional studies.

Limitations

• Specific row counts, file sizes, and detailed column names are not provided by any source.
• Sources conflict on the 'last updated' date, with one listing 2014 and another listing 2026.
• License is ambiguously listed as 'other-license-specified', requiring further investigation for reuse.
