GatorEye data usage Terms and Conditions
Use of GatorEye data, workflows, or derivative products (hereafter referred to as 'GatorEye data') is offered for viewing purposes only. All other uses are strictly prohibited except as described herein. Uses other than viewing may be allowed only after initiating a discussion with and receiving written permission of both co-directors Eben Broadbent and Angelica Almeyda Zambrano in their sole discretion. Usage permission will only be granted on a study-by-study basis (e.g., publication, presentation, poster, report), who maintain final approval of the version. Studies using GatorEye data will be conducted in close collaboration with the co-directors, specifically as relates to drafting the work and revising it critically for intellectual content, and who will be offered co-authorship on all resulting products (e.g., publications, presentations, posters, reports). As such, the GatorEye co-directors are able to maintain and be held accountable for all aspects of GatorEye related studies, including the accuracy and integrity of all parts of each study. GatorEye field data collection and processing requires extensive work and collaboration, as such additional required GatorEye collaborators may be assigned by GatorEye co-directors on a study-by-study basis. Redistribution of data is not permitted; instead, interested parties should be directed to www.gatoreye.org. Please contact Eben Broadbent with any questions at eben@ufl.edu. If you would like to propose a collaboration, please provide a paragraph summary of what is intended for consideration by the co-directors via email, and we will respond as soon as possible.
To access data please simply agree to the terms and conditions above by typing (or copy / paste) as the password the following text between the quotation symbols "I agree to the GatorEye data usage Terms and Conditions" to access the data download site at the below campaign links.
** All data is provided by default in the closest UTM zone (N/S), WGS-84, and with a vertical datum of either (pre-2020) ITRF 2014 or (post-2020) WGS-84 elliptical, all in meters. Vertical and horizontal epoch dates change with base station date, and are the date of acquisition.

Calibration / Validation / Reference datasets
2018 Florida ACF 05-03-18 and 11-01-18, precision cross-georeferenced (XYZ) and coupled with field cm GNSS points of ground points and understory height in longleaf pine ecosystems - suitable for development of DEM and understory DSM algorithms.
Final products
Lidar data is typically distributed in a folder named 'final products', following processing through the GatorEye lidar multi-scalar post-process workflow prior to distribution (see document for details and citation). The final products specifically are:
A) Digital elevation model (DEM) in raster and LAS grid point cloud format.
B) Digital surface model (DSM) in raster and LAS grid point cloud formats.
C) Canopy height model (CHM) in raster and LAS grid point cloud formats.
D) LAS point clouds in ellipsoidal height, and height normalized (e.g., CHM) against the digital elevation model.
Version updates
09/09/21 - 'GatorEye Lite' data is now being uploaded and provided here as well as 'GatorEye' data. This new system is comprised of a M300 RTK with Zenmuse L1 and Micasense Altum with DLS.

01/15/20 - Gen 3 build complete!
12/22/19 - Gen 3 build in progress which now includes up-welling (Nano) and down-welling hyperspectral sensor (Flame) integration (for line-by-line reflectance calculation), radiometric thermal integration with custom external shutter, upgraded 32 beam long-range Lidar, and high-res visual sensor with 72 degrees FOV upgrades.
12/22/19 - v208, ongoing improvements in code in MSGPD workflow, incorporating code parameter groups, specialized for long-leaf pine forests, and for archaeological applications (field surveys, and dense topography).
12/06/19 - v200 multi-scalar ground point detection (MSGPD) and product workflow released. Now based in R, and incorporating improved interpolation algorithms from LidR for DEM generation.
11/01/19 - v80 multi-scalar ground point detection and product workflow released.
06/15/19 - LiDAR sensor upgraded to 250m range 32 laser sensor (Ultra Puck 32c).

- Digital Surface Model (DSM), 0.5 m resolution, raster .tif format
- Canopy Height Model (CHM), 0.5 m resolution, pit-free algorithm, raster .tif format
- Full point clouds, filtered, elevation 'final elevation merged', .laz format
- Full point cloud, filtered, height above DEM, 'final heightz merged', .laz format
- DSM point cloud, 0.5 m resolution, interpolated non-reflective ground spaces (e.g., asphalt, water), .laz format, 'canopy_thin_ground_filled_merged_thin'
10/10/18 - LiDAR firmware upgrade reduces sun related noise.
09/15/18 - Post-processing LiDAR workflow products will be shared for all missions, starting to work through them now. Hyperspectral data shared for selected missions as it is processed. Note: Mosaic (3 to 1 band spectral binned) hyperspectral data is available for 2018 Florida OSBS Lake McCloud as today.
02/02/18 - Future LAS data will be provided as LAS version 1.2 for greater compatibility with open source software. In the LiDAR folder we will have an additional folder named the version of the LAS file if multiple LAS versions are provided.
01/31/18 - Lever Arm (IMU to GNSS Antenna) values corrected. All LiDAR versions after this date have correct lever arm values included (via IE processing) and are at full density (per 12/01/17 update below). We will now also provide flight line point cloud (.las) for each mission, as well as merged flight lines unique to each plot (if it is a plot based mission). We are also providing .tif versions of all RGB images with an associated Pix4D format file having SBET IE differential corrected location and view angle values (accurate to within < 2 cm XYZ).
12/01/17 - New LiDAR processing workflow increases point cloud density by 2400%. LiDAR data folders after this date (standard folder format will be "LiDAR_vMMDDYY" are at full point cloud density.
