LTAR Data Inventory

There is a current network-level effort to inventory all cross-domain datasets for LTAR.  The purpose of the LTAR Data Inventory project is to enable the 18 LTAR sites to outline data holdings that will enhance data discoverability and data sharing across the LTAR network.   

The full data inventory and and Insights for ArcGIS exploratory dashboard can be accessed here (last four tabs): https://gpsr.ars.usda.gov/ltar

LTAR Standard GIS Data Layers

This effort created a geodatabase of standard GIS layers that represent locations and areas associated with the USDA Long-Term Agroecosystem Research (LTAR) Network as of 2021. The geodatabase includes spatial data describing LTAR site locations, addresses, experimental plots, fields and watersheds, eddy flux towers, and phenocams. There are six data layers in the geodatabase available to the public. This geodatabase was created in 2019-2020 by the LTAR network as a collaboration between the LTAR Remote Sensing and GIS working group and the LTAR Data Management working group. The process to create the geodatabase began with initial requests to LTAR site leads and data managers for geospatial data, followed by meetings with each LTAR site to review the initial draft. Edits were documented, and the final draft was again reviewed and certified by LTAR site leads or their delegates. Revisions to this geodatabase will occur biennially, with the next revision scheduled to be published in 2023.
