Future of LandsatFuture of Landsat

The Administration has directed NASA and the USGS to team up on development, launch, and operation of a free-flyer “Landsat Data Continuity Mission (LDCM)”

NASA will procure an on-orbit data acquisition capability

USGS to operate and ingest, archive, process, and distribute Landsat-continuity data products.

Visit the LDCM Documents page at http://ldcm.usgs.gov/documents.php

Future of Land ImagingFuture of Land Imaging

The White House has initiated a year-long study called The Future of Land Imaging

To explore options for United States operational use of satellites to better serve society.

The USGS serves on the leadership team of this Federal interagency working group.

Grid Data Node ExperimentsGrid Data Node Experiments

Recently hosted a visit by representatives of the Geophysical Network (GEON) grid user community to explore possibilities for collaboration

GEON is an NSF-funded grid network hosted and technically supported by SDSC

We are exploring scenarios for experimenting with different access methods with different data products such as:

USGS LiDAR point cloud data National Elevation Dataset (NED) DEMs Landsat data

Our goal to learn how to implement operational data node relationships with various grid communities.

Will share initial lessons-learned at WGISS #23.
