Code Hub
NEON's data are often complex; working with data can be greatly simplified using software or code. We provide some code to get you started, like with our `neonUtilities` package for R, and also post links to code contributed by members of the community. The NEON-related code resources listed below are designed to make working with all NEON data easier, to perform common algorithms on select data products, and to share the code used to generate select data products.
Most code resources that were created by and are managed by NEON can be found in the NEONScience GitHub organization. The code is free and open access to download and utilize. The code found in the NEONScience GitHub organization is published and maintained by NEON project scientists.
Other code resources listed below are created by data users interested in sharing their code. If you have requests for coding resources, challenges with NEON data or ideas for creating NEON data-related code, we encourage you to learn more about how we categorize NEON-related code resources, and how you can submit your own code resources.
Code resources are provided at three tiers, differing in level of review by NEON:
| Tier 1: Community Contributed Code | Community contributed code is reviewed to determine that it is publicly available, generally comprehensible, and involves NEON data. Code functionality is not evaluated. |
|---|---|
| Tier 2: NEON Certified Code | Certified code goes through a code review, to ensure it performs as described and without error. |
| Tier 3: NEON Production Code | Production code is used in NEON data processing pipelines, to generate NEON data products. It is the end product of a very long and careful development process. |
Search the table below to find code that might be useful for your project.

ecocomDPA flexible dataset design pattern for ecological community data to facilitate synthesis and reuse Tier 2: NEON certified code R language This R package provides tools to discover and work with biodiversity data that follow the ecocomDP design pattern, including wrapper functions to search for and download data from the NEON and EDI data portals. See O'Brien et al (2021) for an overview. See the GitHub repo for more information about the data model, tools to work with the data model, and information about planned enhancements and updates.

neonUtilitiesAccess NEON data programmatically and stack downloaded files with this handy R package. Tier 2: NEON certified code R language This package is available to install directly through CRAN. It includes functions for accessing NEON data via the API, a function to join (stack) the month-by-site files in downloaded NEON data, and functions for more specialized data access and conversion, such as extracting flux data from the published HDF5 format and converting data to geoCSV format.

NEON tree crown areaCalculate crown area of woody plants as seen from above based on height and diameter measurements. Tier 1: Community contributed code R language The dataset NEON.DOM.SITE.DP1.10098.001 - Woody plant vegetation structure provides structure measurements, including height, canopy diameter, and stem diameter, as well as mapped position of individual woody plants. However, crowns can overlap and they can also be fully contained within other crowns. In this script, overlapping crown areas are assigned to the taller individual, or split among individuals with the same height. Crown areas of smaller individuals completely covered by taller individuals are omitted. Data products:
