The Bureau of Land Management (BLM) leverages ground, air and spaceborne remote sensing technologies to support its mission to sustain the health, diversity, and productivity of public lands for the use and enjoyment of present and future generations. These technologies include aerial and close-range photography, multispectral, hyperspectral, and thermal infrared camera/imaging systems, as well as radar and light detection and ranging (lidar). The BLM also utilizes passive and active imaging system information collected by uncrewed aircraft systems (UAS). Remote sensing data and products are being used to address a host of BLM monitoring requirements, including energy development, mine production verification, assessment of land cover condition through time, and wildfire response and mitigation. Finally, the BLM requires field-based measurements to support management decisions covering vast expanses of land. By integrating remote sensing into the BLM's Assessment, Inventory, and Monitoring strategy, field-based data are used to generate information and maps that support land management decision making. The BLM is leveraging remote sensing to provide an integrated, quantitative monitoring approach to efficiently and effectively document the impacts from authorized and unauthorized disturbance and land treatment activities at local and regional scales.

Monitoring Forest Cover and Condition

Submitted by tadamson on

The Bureau of Land Management (BLM) National Operations Center (NOC) and the Medford District Office (MDO) are using multi-scale, multi-temporal remotely sensed imagery to monitor forest cover and condition in BLM-administered lands in southwestern Oregon. The NOC employed cloud-computing architecture to efficiently derive a suite of Sentinel-2 10-meter resolution satellite image mosaic products spanning the entire MDO.

Handheld Laser Scanning to Document Coastal Erosion

Submitted by tadamson on

Coastal erosion, exacerbated by sea-level rise, threatens natural, cultural, and recreation resources in the King Range National Conservation Area (NCA) on the northern California coast. Within this otherwise steep landscape, the flat coastal terrace provides a suitable location for recreation infrastructure, including two historic lighthouses and the popular Lost Coast Trail.

LandCART (Landscape Cover Analysis and Reporting Tools)

Submitted by tadamson on

The Bureau of Land Management (BLM) National Operations Center (NOC), through a National Aeronautics and Space Administration (NASA) Research Opportunities in Space and Earth Science grant, partnered with researchers from the U.S. Geological Survey and University of California–Los Angeles to create an online mapping application called LandCART: Landscape Cover Analysis and Reporting Tools. LandCART V1.0 was released on February 16, 2022.

Close-range Photogrammetry for Monitoring Cultural Sites

Submitted by tadamson on

Using close-range photography to create finely detailed 3D models of culturally significant archeological sites facilitates both documentation and research. The Bureau of Land Management (BLM) Buffalo Field Office hosted its 14th Volunteer Archeology Project the week of June 26, 2022, utilizing the Passport in Time (PIT) program.

2022 DOI Remote Sensing Activities

Remotely sensed data and derived information contribute significantly to mission-critical work across the Department of the Interior (DOI). This report from the DOI Remote Sensing Working Group (DOIRSWG) highlights a sample of DOI remote sensing applications and illustrates the many types of technology, platforms, and specialized sensors employed.* DOI personnel use remote sensing technology to evaluate and monitor changing land-surface and natural resource conditions over the vast areas for which DOI has responsibility.

Monitoring Managed Lands Using Synthetic Aperture Radar

Submitted by atripp on

The emergent proliferation of Synthetic Aperture Radar (SAR) imaging systems, related advancements in image processing and exploitation capabilities, and the increasing availability of analysis-ready SAR data products have enhanced the BLM’s ability to use remote sensing-derived information to support resource management.
