Abstract

Mapping and Serving Alaska's first statewide digital ortho-imagery base map
Track: Imagery and Raster
Authors: Pete Hickman, Tom Heinrichs, Tony Follett

Alaska's Statewide Digital Mapping Initiative will provide government and private stakeholders with an accurate and up-to-date digital base map. The new 2.5-meter, 1:24,000 scale accuracy (CE90 of 12.2-meters), multispectral ortho-imagery will cover the entire 1.7 million square kilometers of the state and allow a multitude of geospatial applications such as resource management, transportation planning, glacier mapping, and change detection. Statewide imagery data had not been collected for Alaska in 30 years; this is the first time a GIS-ready, statewide, ortho-imagery base map will be available.

This presentation will discuss the challenges of making this massive imagery data set available via web services to a variety of private and government organizations. The presenters will also discuss how both ArcGIS and open source technologies are being leveraged to support data acquisition and production operations, geospatial data delivery and quality assurance involving a large number of participating agencies and project stakeholders.
