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..


How to create Geometry using WellKnown Text

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) 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 (WKT) SELECT

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.

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) SELECT

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.


GitHub creof/wktparser Parser for wellknown text (WKT/EWKT) object strings

Well Known Text. The Well Known Text format (hereafter WKT) provides a text representation of a geometric shape. It can be used to: Build instances of various shapes (e.g., using ST_MakePolygon on a Linestring). Convert existing shapes to a text representation for ease of reading. Each shape in WKT has a tag which says what it is, usually.


Well Known Text (WKT) SELECT

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.

This International Standard defines the structure and content of well-known text strings. It does not prescribe how implementations should read or write these strings. The jointly developed draft has also been submitted by ISO TC211 for publication as an International Standard document.


Well Known Text (WKT) SELECT

The OpenGIS Consortium Simple Features for SQL specification defines the well-known text format to exchange geometry data in ASCII format. This format is also referenced by the ISO SQL/MM Part: 3 Spatial standard. The well-known text format of a geometry is defined as follows:


Well Known Text (WKT) SELECT

Well Known Text (WKT) is an Open Geospatial Consortium (OGC) standard that is used to represent spatial data in a textual format. Most OGC-compliant systems support Well Known Text. Spatial functionality in SQL Server 2008, 2012, and SQL Azure can easily convert between a spatial object in the database and WKT.
