Well Known Text (WKT) SELECT

Well-Known Text (WKT) Well-Known Text (WKT) is an ASCII representation of a spatial object. WKTs are not case sensitive; Vertica recognizes any combination of lowercase and uppercase letters. Some examples of valid WKTs are:

Well-known text representation of coordinate reference systems (WKT or WKT-CRS) is a text markup language for representing spatial reference systems and transformations between spatial reference systems. The formats were originally defined by the Open Geospatial Consortium (OGC) and described in their Simple Feature Access and Well-known text representation of coordinate reference systems.

What does WKT stand for? WKT stands for Well-Known Text and is a text representation of geographic features, including points, lines, and polygons, used in GIS (Geographic Information Systems). WKT is widely used to describe the geometry of geographic features in vector data, as well as in many GIS software applications and web mapping APIs.

Well Known Text (WKT) is a way of representing objects on a map, and are supported by a number of databases including Microsoft SQL Server. Icon Map supports displaying Point, MultiPoint, LineString, MultiLineString, Polygon and MultiPolygon objects, therefore providing good support for the SQL Server Geography datatype.

Well-known text (WKT) is a text markup language for representing vector geometry objects on a map, spatial reference systems of spatial objects and transformations between spatial reference systems. A binary equivalent, known as well-known binary (WKB) is used to transfer and store the same information on databases, such as PostGIS.

"Well-known text" is a scheme for writing a simple features geometry into a standard text string. Examples POINT (0 0) POINT EMPTY LINESTRING (0 0, 0 1, 1 2) LINESTRING EMPTY POLYGON ( (0 0, 1 0, 1 1, 0 1, 0 0)) POLYGON ( (0 0, 4 0, 4 4, 0 4, 0 0), (1 1, 1 2, 2 2, 2 1, 1 1)) POLYGON EMPTY MULTIPOINT ( (0 0), (1 1))

WKT or Well-known Text. It's useful to recognize this format given many tools - including ESRI's ArcMap and ENVI use this format. Well-known Text (WKT) is a for compact machine- and human-readable representation of geometric objects.It defines elements of coordinate reference system (CRS) definitions using a combination of brackets [] and elements separated by commas (,).

Well-known text (WKT) offers a compact machine- and human-readable representation of geometric objects. WKT may also be used for succinctly describing the critical elements of coordinate reference system (CRS) definitions. WKT was described in the Open Geospatial Consortium implementation specifications 99-036 through 06-103r4 and ISO 19125-1:2004.

Well-known text (WKT) is a human readable representation for spatial objects like points, lines, or enclosed areas on a map. I came across WKT files as I was getting started with a Geofencing project. With WKT, you can specify an area that's interesting to you and then see if some geolocation information like a lat/long pair from a mobile.
