The following sections outline and describe both types of collaboration and highlight how public domain remotely sensed imagery is used in a wide range of contemporary issues involving data access, education and outreach, and applied research. Texas required more Landsat scenes than West Virginia). Many of the early data archives were based on the USGS Global Visualization Viewer, GloVis, a web-based spatial search engine for identifying and downloading scenes via a simple interface. The USGS worked closely with AmericaView to develop the utility, the fi rst archive tool with national coverage designed to get Landsat and other pubic domain data out on the Internet for free. As an example, during the 2005-06 funding year, 14 funded StateViews delivered 38 Gigabytes of imagery to users in government agencies, academia, the non-profi t sector, and private industry. Since November 2009, Landsat data have been made available at no cost through GloVis and EarthExplorer, reducing the need for the original StateView archives. Yet despite this, many StateViews continue to maintain their archives, hosting other geospatial datasets including MODIS and ASTER imagery, digital raster graphics, lidar data, kml fi les, NAIP imagery, radar data, and digital elevation models. In some cases, continued on page 972 Oct ober 2011 971 Data Archives Access to public domain satellite data was limited, both in terms of availability and ease of access when AV was fi rst formed. To address this, each StateView member was initially required to develop and maintain a free, public data archive. Landsat imagery was the key component, although many StateViews provided additional data from other public domain sources. Guidelines for archive development were fl exible, given the differing spatial extent of each state (e.g., Photogrammetric & remote SenSing ric engineering engi Publication List Using a screen reader?
