The USGS is coordinating a 3D Elevation Program (3DEP) effort with other Federal agency partners and the State of Alaska to acquire new statewide Alaska elevation data. Under its Geospatial Products and Services Contract (GPSC), the USGS is contracting with vendors to acquire 5-meter resolution elevation data using Interferometric Synthetic Aperture Radar (InSAR) sensors flown on aircraft.
The North American Land Change Monitoring System (NALCMS) is a collaborative initiative between Canada, Mexico, and the United States to monitor land cover and its change over time.
The USGS has completed and released the National Land Cover Database (NLCD) 2016 for the United States. NLCD 2016 documents land cover in the conterminous United States from 2001 to 2016.
The USGS has completed and released the National Land Cover Database (NLCD) 2016 for the United States. NLCD 2016 for the first time includes fractional component products of shrub, bare ground, and grassland areas in the western United States.
A new suite of science products has been released, including Burned Area, Dynamic Surface Water Extent, and Fractional Snow Covered Area. These new products span the USGS Landsat archive from 1982 to the present and leverage the U.S. Analysis Ready Data (ARD) data released in fiscal year 2017.
To validate the quality of light detection and ranging (lidar) data collected for the 3D Elevation Program (3DEP), the USGS uses methods detailed in “Accuracy Standards for Digital Geospatial Data” developed by the American Society for Photogrammetry and Remote Sensing (ASPRS).
Landsat satellites have been operating since 1972, providing the longest continuous observation record of the Earth’s land surface. Over the past half century, the Landsat user community has grown exponentially, encompassing more diverse and evolving scientific research and operational uses. Understanding current and future user needs is crucial to informing the design of Landsat missions beyond Landsat 9.
Landsat satellite imagery has been available at no cost to the public since 2008, resulting in the distribution of millions of scenes each subsequent year. Additionally, tens of thousands of Landsat users have registered with the USGS to access the data. Considering the number of Landsat data users worldwide and the broad range of Landsat data applications, it is difficult to quantify the cascading benefits to society.
The National Map Corps (TNMCorps), a crowdsourced mapping project, relies on volunteers to assist the USGS National Geospatial Program by collecting and editing man-made structures data for The National Map. Through their participation, volunteers make important contributions to the USGS’s ability to provide the Nation with accurate mapping information.
As part of a Natural Resource Damage Assessment settlement related to contaminant releases from the Molycorp/Questa Molybdenum mine, subalpine fens, wetlands, and associated stream habitat for the native Rio Grande cutthroat trout are being restored in high-altitude headwaters of Bitter Creek, New Mexico.
