ESA Workshop: Mapping Ecosystem Changes using NEON Airborne Remote Sensing Data in Google Earth Engine

Aug 18, 2022

Hosted By:

Ecological Society of America

Description

This interactive workshop focuses on the use of Google Earth Engine (GEE) to analyze remote sensing data using reproducible science workflows, covering fundamental concepts required to visualize, process, and analyze NEON hyperspectral and LiDAR data. The workshop will highlight specific ecological applications at different spatial and temporal scales. Participants will leave with knowledge of how to use NEON AOP data in GEE, and will be provided with a number of ready-to-use GEE scripts that can be expanded upon to further the participants' research interests.   

Background

Each year the National Ecological Observatory Network鈥檚 Airborne Observation Platform (AOP) collects high-resolution hyperspectral imagery, discrete and waveform lidar, and RGB photography at 81 terrestrial and aquatic sites throughout the United States. The coincident collection of AOP data with over 150 additional NEON data products from both instrumented and observational systems provides a rich resource for carrying out ecological research at multiple scales. However, one of the major barriers to using AOP data has been its sheer volume, which requires computationally intensive and expensive computing resources. Google Earth Engine (GEE) is a free, cloud-based platform that has become a powerful tool for conducting spatial analysis on terabyte-size datasets, such as the NEON airborne data collection. With just an internet connection and a google account, anyone can use GEE to conduct advanced geospatial research.

Prerequisites

Participants should have a basic knowledge of remote sensing and some experience coding in a scientific programming language (eg. Python, R, JavaScript), though coding proficiency is not mandatory.
