Topographic data (LIDAR) of field activity A-1-03-MD in
Chesapeake Bay, Maryland from 01/01/2003 to 03/01/2003,
http://walrus.wr.usgs.gov/infobank/a/a103md/html/a-1-03-md.meta.html.
These data and information are intended for science
researchers, students from elementary through
college, policy makers, and general public.

LIDAR
Notes -
Light Detection and Ranging (LIDAR) is a method of locating objects
on the ground using aerial-borne equipment. It is similar to RADAR or SONAR in
that the two-way travel time of an energy beam reflected off an object is
precisely measured, but this technology uses laser light instead of radio or
sound waves. This technology has proven very useful in remote sensing of the
earth. It can be used for determining elevations of both the earth's surface
and items (natural and man-made) on the surface. Analysis of LIDAR data is
used in detailed modeling of the earth's surface for drainage and floodplain
studies, determining how a new structure will affect views from various locations,
shoreline erosion studies, and other reasons. The Bare Earth Mass Points are
point elevations that represent the "bare earth." Features that are above the
ground - such as buildings, bridges, tree tops, etc. - have been eliminated.
Similar information is available for thousands
of other USGS/CMG-related Activities.
If known, available are Activity-specific
navigation, gravity, magnetics, bathymetry,
seismic, and sampling data; track maps; and
equipment information; as well as summary
overviews, crew lists, and information
about analog materials.
If available, access to physical samples is
described in the "WR CMG Sample Distribution
Policy" at:
