- The linked artifact documents the current public release. Research findings require their own paper or dataset record.
The portfolio collects eight selected artifacts: classified LiDAR and building visualization from Atlanta, a 2026 North Carolina terrain diagnostic, a southern Haiti marine survey design with its coverage simulation, a building-age map, a terrain surface, and a New Markets Tax Credit figure. Several are academic exercises or group work, and each entry labels its credit and limits.
The North Carolina diagnostic compares an independently processed ground surface with a reported raster artifact. Missing cells inside the inspected building footprint rise from 38.6% at 3-foot cells to 77.1% at 1-foot cells and 87.5% at half-foot cells; the acquisition date of the supplied LAS file was not established.
The Haiti terrain model is an original 525,474-triangle mesh of gridded land elevation and seabed bathymetry at 100 m sampling, with land exaggerated 1.2 times and seabed 6 times. Its vertices are gridded elevations, not LiDAR returns, photogrammetry or navigation data. Metadata records the GMRT, Mapzen, USGS and NOAA sources and licences.
