[data models] A map feature that bounds an area at a given scale, such as a country on a world map or a district on a city map.

SELECT the_geom as polygon FROM usa WHERE state = 'Kentucky';
This will return a geometry object containing the polygon of Kentucky.

Polygon Split Merge
Any polygonal feature can be split and merged with the new split and merge tools. Any rules that are defined in the Bentley Map project will be applied to the resulting attributes.

polygon : A multisided figure that represents area on a map. A feature defined by the arcs that make up its boundary. Every polygon contains one label point within its boundary.

Polygon-on-point selection
Polygon-on-point selections are the reverse of the previous case. Here, we are interested in the value of polygons which lie on top of selected point features.

Polygon
A feature which represents areal elements. Polygons are defined by bounding arcs and contain one label point which relate to the attribute table.

Polygon - An arc that closes on itself to make a circle or a closed shape. An example of a set of data that would be stored in the GIS in this format would be parks or lakes.

Polygon: A two-dimensional figure with three or more sides that represents an area on a map.

Polygon: A coverage used to represent areas. A polygon is defined by the arcs that make up its boundary. Polygons have attributes that describe the geographic feature they represent.

polygon map
polygon mapping
Defines the borders of homogeneous features as well as the characteristics associated with those features which identify special land related information (e.g.

polygon
A coverage feature class used to represent areas. A polygon is defined by the arcs that make up its boundary and a point inside its boundary for identification.

polygon overlay A topological overlay procedure which determines the spatial coincidence of two sets of polygon features and creates a new set of polygons based on identity, intersect, or union.

Polygon A vector representation of an enclosed region, described by a sequential list of vertices or mathematical functions.

Polygon Topology Table
Below are four polygons (A - D) with a Node Topology Table describing their location with respect to one another. Numbered 1 - 7 are the arcs that make up the polygons. The nodes that connect the arcs are numbered I - V.

Polygon Draws the surface using filled polygons (most realistic).
Wire/Poly Draws the surface using filled polygons, but with wire mesh draped over it.
Grid Style Sets the style for drawing the fast display mode surface.

G-polygon -- an area consisting of an interior area, one outer G-ring and zero or more nonintersecting, nonnested inner G-rings. No ring, inner or outer, shall be collinear with or intersect any other ring of the same G-polygon.

Owner Polygon
A single polygon feature class that represents land with taxable information about the owner, taxes, land use, etc.

line-in-polygon : A spatial operation in which arcs in one coverage are overlaid with polygons in another to determine which arcs, or portions of arcs, are contained within the polygons.

Polygons: An area fully encompassed by a series of connected lines. Because lines have direction, the system can determine the area that falls within the lines comprising the polygon. Polygons are often an irregular shape.

POLYGON
An area bounded by a closed line. It is used to describe spatial elements, such as housing and industrial units, administrative and political districts, and areas of homogeneous land use and soil types.

Polygonal structures of varying sizes appear on Mars. Some consider these to be volcanic in origin (see next page); others cite them as related to ice-produced features in deposits related to glaciation.

Zones, polygons, and regions are GIS terms for groups of lines that enclose areas such as state boundaries, property lines, and soil type delineations. Complex polygons may contain islands consisting of other polygons or unmodeled areas.

In each polygon, we now have a total of the sum of its angles minus (where is the number of sides) plus . Since the sum of the angles of any polygon is , this is 0. Therefore,

Universe Polygon - the first record in a polygon attribute table, for example. It represents the area beyond the outer boundary of the coverage. It's the only polygon that never has a label point, and so has a User-ID value of 0.

Automatic Polygon Layer Creation: Create polygon layers automatically from vectorized lines with just one command. The closed polygons can then be edited, and labeled using R2V's line editor.

In terms of polygons, the geographic centre or the average of the x and y values making up the perimeter points.

A Word About Polygons
At this time, Google Maps does not provide the ability to generate true polygons, but I suspect that this will change in the near future as the API becomes more robust.

Clipping an Ocean Polygon
When building a geographic database representing a coastal area, your census data and your digital elevation model will extend beyond the shoreline and make it difficult to make maps that look decent.

In geographical terms, discrete data can be represented by polygons. Sometimes referred to as integer data. In contrast, see continuous data. Dot map Simple thematic technique using dots to show the spatial distribution of a chosen element.

These features can resemble circles, polygons, nets, steps, and stripes. The development of some of these shapes is thought to be the result of freeze-thaw action.

Buffer: A polygon enclosing an area within a specified distance from a point, line or polygon. Accordingly, there are point buffers, line buffers and polygon buffers.

be/ centroid The term given to the center of an area, region, or polygon. In the case of irregularly shaped polygons, the centroid is derived mathematically and is weighted to approximate a sort of `center of gravity.

For example, dots or points on a map layer may represent the location of schools, a line may represent a river, and a polygon may represent the outline of an area such as a county.

The Group Agents are associated with sets of polygons ordered by geometric patterns (polygon clusters, sequence of polygons along a fictive line), thematic identity or similarity, topologic partition, or geographic regions.

These maps comprise of polygons which are created from the base map, which shows the details of the ownership of the properties and related information.

For example, cities on a map of the world would be represented by points rather than polygons. No measurements are possible with point features.

In topological models (Fig. 6), a polygon is defined by a series of arcs. Arcs begin and end at nodes, which occur wherever two or more arcs meet.

The test network observed should be a polygon with station spacing not less than 50 meters and not more than 10 kilometers.

arcs, nodes, polygons, and points). For example, the topology of an arc includes its from- and to-nodes, and its left and right polygons.

Buffers are created as polygons because they represent an area around a feature. Buffering is also referred to as corridor or zone generation with the raster data model.

Attributes are data that describe the properties of a point, line, or polygon record in a Geographic Information System. For example, imagine a GIS coverage in which points represent sites on a landscape.

To avoid this problem, I create a rectangular polygon shapefile that encloses the entire extent of the map, using the clip feature of the Geoprocessing Wizard (under the "Tools" menu) to subtract everything except the sea.

I believe that the first vertex of the gring (polygon) is the upper left (northwest) which would be 33.9744N 35.4294E and they proceed in a clockwise direction
so the southwest coordinate would be the last pair, in this case 33.3364N
35.4116E.

21] which signifies the outer limit for alternative locations (alternative to the location with minimum aggregate transport costs) in a Weberian locational triangle or other polygon.

In the vector model, information about points, lines, and polygons is encoded and stored as a collection of x,y coordinates. The location of a point feature, such as a bore hole, can be described by a single x,y coordinate.

The Erase button and the Erase with Polygon buttons allow the user to remove a series from the graph without opening the table. The Erase button is used by clicking on it and then pointing and clicking the cursor at the series to be removed.

The moPointInPolygon is one of the search methods in SearchShape. It is used to return polygon features that contain the first coordinate of the search feature (ESRI, 1996b).
