New Alaska IfSAR Data
Provides Detailed Elevation Information
New Alaska Topographic Maps
USGS 'US Topo' Digital Format
The Alaska Mapping Initiative (AMI) is a collaborative effort of the USGS, other federal agencies, and the State of Alaska to create updated topographic data and maps for all of Alaska. The Alaska Mapping Executive Committee (AMEC) was formed to coordinate and promote this ambitious effort to ensure that Alaska mapping standards are similar to the rest of the United States.
Alaska Mapping Initiative: Modernizing Alaska Mapping
The goal of the Alaska Mapping Initiative (AMI) is to acquire and enhance foundational digital map layers such as elevation, surface water, roads, buildings and boundaries. Updated map layers are used to produce a new US Topo map series for Alaska statewide. This multi-year mapping initiative will benefit high-priority applications in human safety, planning, research, and resource management.
New Elevation Layer Being Acquired Statewide for Alaska
New 5-meter resolution elevation data are being collected by airborne radar statewide for Alaska. The new data are acquired using Interferometric Synthetic Aperture Radar (IfSAR) technology, and are replacing decades-old 60-meter elevation data. Alaska IfSAR data are made available free to the public as an element of the national 3D Elevation Program (3DEP).
Alaska Mapping Executive Committee
The Alaska Mapping Executive Committee (AMEC) was formed in November of 2012 to coordinate the acquisition of critical Alaska map data. Executive level managers from 15 Federal agencies and Departments and the State of Alaska serve on the AMEC.
