NGA GRiD Foundation GEOINT Access

RestrictedL4Data productElevationLiDAR · active optical3DVector

Government access channel for foundational elevation, point clouds, meshes and related geospatial content. Requires provider authorisation and applicable credentials. Public directory metadata only; actual regional holdings, product dates and rights must be verified within GRiD.

Access

Restricted to authorised government users

This source is listed so it can be discovered alongside everything else in the fabric. Access is arranged directly with the operator under a government agreement, so TerraFabric cannot quote, order or task it, and it never appears in coverage rankings or OSINT.

Published access-channel metadata only. Extent is nominal geographic scope, not actual holdings; authorisation required.
