Accessing Airborne Data
New on the portal! A subset of airborne data products are now available to download from the data portal. If you are interested, we encourage you to test out accessing airborne data via the portal and give us your feedback. We hope to have the majority of our airborne data available through the portal in the next few months.
In the meantime, you can still access the full repository of 2013-2017 flight data via our request form.
Airborne remote sensing flight surveys are conducted by the NEON project to collect quantitative information on land cover and changes to ecological structure and chemistry, including the presence and effects of invasive species across landscapes 100-300km2 surrounding NEON sites.
Types of data
Data are collected during peak greenness at each field site and include the following:
- DSM (Digital Surface Model; full mosaic)
- DTM (Digital Terrain Model; full mosaic)
- CHM (Canopy Height Model; full mosaic)
- Slope and Aspect (full mosaics)
- Classified point clouds (points classified as ground, building, vegetation, and unclassified; 1 km2 tiles)
- Unclassified point clouds (points by flight line)
- KML (site and flight line boundaries)
- Full waveform data
- Surface reflectance, recorded across 426 narrow spectral bands extending from 380 to 2510 nm with a spectral sampling of five nm. Vegetation indices including NDVI, EVI, ARVI, Xanthophyll, Lignin, fPAR (fractional Photosynthetically Active Radiation) and LAI (Leaf Area Index)
- Orthorectified digital photographs
- Camera mosaic
- ASD Spectral Data
* Please note that much of the data currently available were collected as part of Engineering Flight Campaigns, they are considered "engineering quality" and may not have sufficient QA/QC to meet all users' needs.
Requesting airborne data
NEON airborne data are freely available. Depending on the type of data you request, we will either provide a user account for you to access an online repository of airborne data or we may send you a hard drive of the data. Please note that we are constantly adding new datasets to our online repository and once you have an account, you will be able to explore and download data as they become available.
