<scope-and-purpose>The ADL Catalog provides geospatial data and
metadata in digital (both online and offline) and hardcopy form.  As
of January 2000, coverage is worldwide but concentrated on Southern
California.  Major online, digital series in the collection include:
<link url="http://edc.usgs.gov/Webglis/glisbin/guide.pl/glis/hyper/guide/drg">DRG</link>s
(digital raster graphics: scanned <link
url="http://www.usgs.gov/">U.S. Geological Survey</link> topographic
maps) for California; <link url="http://www.spot.com/">SPOT</link>
satellite images for California; and scanned maps of foreign
countries.  Major metadata-only series include: Geodex (sheet-level
records for mainly topographic maps, worldwide); frame-level records
for aerial photography acquired from the <link
url="http://www.arc.nasa.gov/">NASA/Ames Research Center</link>
(mainly U.S.); and scene-level records for <link
url="http://geo.arc.nasa.gov/sge/landsat/landsat.html">Landsat</link>
<link url="http://edc.usgs.gov/Webglis/glisbin/guide.pl/glis/hyper/guide/landsat">Multispectral
Scanner</link> imagery (worldwide).  Most items in the ADL Catalog are
held by the Map and Imagery Laboratory; Geodex reflects holdings of
other major map collections in California.</scope-and-purpose>
