Shorelines: There appears to be no metadata associated with the shorelines; we will guess that they are stored on either NAD27 (the most common datum).
shoreline The line separating land and water. Fluctuates as water rises and falls.
sial The upper layer of the continental crust, so called because it is rich in silica and aluminum oxide. compare sima.
sialic Enriched in sial.
Shoreline: Position Approximate
A shoreline compiled from information of an undetermined accuracy

The shoreline at Palm Beach, New South Wales
The Pacific contains about 25,000 islands (more than the total number in the rest of the world's oceans combined), the majority of which are found south of the equator.
i.e. shorelines provide additional contours
finally, an algorithm is used to interpolate elevations at every grid point from the contour data
by photogrammetry ...
Contours and Shorelines portray elevation of the land and ths direction and steepness of slopes.
Drainage lines stipulate the places where slope breaks from up to down.
Spot Elevations show places of measured height that fall between contours.

Shoreline The line that separates a land surface from a water body. Also see coastline. Short Wave A small wave in the polar jet stream and the westerlies that extends from the middle to the upper troposphere.
Physical examples of breaklines are ridge lines, streams, and lake shorelines. Buffer A zone of a given distance around a physical entity such as a point, line, or polygon.
The piling up of water along a shoreline cause by the sustained winds of a strong storm - usually a hurricane..
Strain:
A change in the volume or shape of a rock mass in response to stress.
Stratification: ...
See: shoreline mean low water Tidal datum that is the arithmetic mean of the low water heights observed over a specific 19-year Metonic cycle (National Tidal Datum Epoch).
the May and Tanner (1973) theory of coastal cell evolution used in Raper and Livingstone (1995) which relates wave crest convergence at the shoreline to the distribution of wave power along the shoreline.
Streams that develop during Youth follow the gradient (slope) from the highest land to the ocean shoreline start and cut down narrow, steeper-walled valley slopes.

In digitizing a lake, for example, the shoreline can be indicated as a series of points and line segments.
Base maps of roads, shoreline, elevation, and current flow formed the basis of the application. Separate suitability models were developed for three alternative land uses-- conservation, research and development.
In addition, a certain amount of shoreline is included or shown on most hydrographic surveys to clearly show the separation of water and land.
Hydrographic surveys are horizontal and/or vertical plane surveys.

Emergent Coastline:
A shoreline resulting from a rise in land surface elevation relative to sea level.
Enclave:
A tract or territory enclosed within another state or country.
This map depicts the North Carolina shoreline, including marinas and boatyards. A ferry schedule is shown at the bottom right. This map was produced with the aid of Bentley CADscript.
Graphics: Come from two sources: 1. Paul S. Anderson, these are graphics containing the graticule shorelines and 2. Shaded maps by Peter H. Dana, The Geographers Craft Project. Department of Geography, The University of Texas at Austin.
Other records, such as shoreline and flood hazard boundary maps, flood insurance surveys, and storm damage reports, and including records provided local officials by the State Department of Environmental Conservation, ...
The data and includes major roads and geographic features, inland bodies of water, shoreline hydrography, and the latest agreed and disputed jurisdiction boundaries.
[data editing] Converting short connected straight lines into smooth curves to represent features such as rivers, shorelines, and contour lines. The curves that result pass through or close to the existing points.
A scanner flown on National Oceanic and Atmospheric Administration (NOAA) polar-orbiting satellites for measuring visible and infrared radiation reflected from vegetation, cloud cover, shorelines, water, snow, and ice.
and August projections for designing maps emphasizing nearly-continuous seas, Atelsthan Spilhaus proposed more complicated approaches, like a modified (not equal-area) Hammer map interrupted in three lobes, or interrupting the map at shorelines ...
Curve Fitting An automated mapping function that converts a series of short connected straight lines into smooth curves to represented entities that do not have precise mathematical definitions (such as rivers, shorelines, and contour lines).
Typical features defined within a planimetric map include such natural and cultural features as streams, roads, shorelines, waterways, building footprints, reservoirs, bridges, roadways, overpasses, sidewalks and parking lots.
This calculation is heavily dependent on data resolution (think of it as a fractal shoreline problem, the more resolution the more detail, the more area, etc). This program uses the CURRENT GRASS REGION, not the resolution of the map.
The figure below shows the Albers Equal-Area Conic projection of the world with shorelines on a 15 degree graticule. The standard parallels are 20 and 60 degrees N. The central meridian is 90 degrees W.
general feature details as building footprints, reservoirs, tanks, docks, piers, airports, bridges, overpasses, underpasses, railroads, parking lots, driveways, other impervious surfaces, streams, lakes, drainage courses, holding basins, shorelines, ...
Stereo-digitized features containing x,y,z values such as streams and shorelines containing an elevation attribute are often stored as breakline features. buffer A zone of a specified distance around coverage features.
