Both products have classification for buildings, low/med/high vegetation, ground, and others, as well as information about return numbers, elevations, etc. The data products come in a series of tiles rather than one big file.", "description": "

These data represent summaries about 2020 LiDAR aggregated to the tile-level. The data are meant to give analysts an idea of data quality. Questions like, \"What proportion of points are unclassified, and is that proportion consistent across the whole study area?\" and, \"How many points are in overlapping flight paths on this tile?\" can be readily answered using this dataset.<\/SPAN><\/P>

Metrics include:<\/SPAN><\/P>

  • The las version specification for the tile<\/SPAN><\/P><\/LI>

  • The tile projection and create-date<\/SPAN><\/P><\/LI>

  • Average density of first returns in pt/m^2<\/SPAN><\/P><\/LI>

  • Minimum and maximum elevations<\/SPAN><\/P><\/LI>

  • The percentage of points that are 1st, 2nd, etc... returns<\/SPAN><\/P><\/LI>
