Alaska Mapped is the state’s main source for current and historical aerial images. The site provides free and public access to three main types of images:
GINA and the Statewide Digital Mapping Initiative (SDMI) collect the data for Alaska Mapped images. SDMI is a cooperative state program that includes federal, state, industrial, and non-profit partners. GINA is also acting as the states lead for the SDMI statewide ortho, using SPOT5 as a data source. The SDMI IFSAR DEM program’s dataset will be made available through the AlaskaMapped archive and services.
The AlaskaMapped archive is made available for search and discovery through the Browse.AlaskaMapped.org web application. This web site allows users to zoom to their area of interest and discover what datasets are available. The focus of the archive is on high resolution imagery and high resolution elevation datasets.
GINA takes many of the datasets integrated into the AlaskaMapped archive and turns them into services and web service feeds. One of the most popular and widely known is the Best Data Layer, a best available imagery layer made from the AlaskaMapped archive. Check out the alaskamapped BDL page for details of how best to use or integrate this valuable Alaskan dataset into your desktop GIS, server, and web application environments.
