Purpose
|
|
The LIDAR-derived data were collected by the Maryland Department of
|
|
Natural Resources in support of shore erosion studies along the shorelines of
|
|
the Chesapeake Bay. It also supports the Federal Emergency Management Agency's
|
|
specifications for mapping floodplains. These efforts required detailed
|
|
elevation data and models, such as those available from LIDAR sensing. The
|
|
data have also been made available to aid in other projects that require
|
|
detailed surface, vegetation and/or structure elevations.

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.
