FGDC SDI Knowledge Directory!

Welcome to the SDI Knowledge Directory.

This directory is a collaborative project to bring together SDI information to advance national, regional and global SDI’s.


This project is under active development. For the past three decades the FGDC has provided leadership in fostering collaboration and developing partnerships for the advancement of local-to-global SDI’s. We will continue to work to mobilize SDI information we have developed over the past 30 years into the SDI Knowledge Directory to serve the geospatial community.
