Difference between notations of WKT format: ‘POINT()’ and ‘Point ()’

What format is a WKT in?

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.

What is the difference between WKB and WKT?

Well-known text (WKT) is a text markup language for representing vector geometry objects. A binary equivalent, known as well-known binary (WKB), is used to transfer and store the same information in a more compact form convenient for computer processing but that is not human-readable.

What is WKB geometry format?

WKB stands for Well-Known Binary, a format for representing geographical and geometrical data. WKB uses 1-byte unsigned integers, 4-byte unsigned integers, and 8-byte double-precision numbers. The first byte indicates the byte order. 00 for big endian, or 01 for little endian.

What is WKT used for?

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

What is the difference between Multilinestring and Multipolygon?

MULTILINESTRING – this is the same as a polyline and can contain multiple sequences of points to represent a stream or road network. MULTIPOLYGON – this is the same as a “polygon” in a shapefile and can contain multiple polygons.

What is well known text line?

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. Two linestrings, one that passes through (0,0), (–1,–2), and (–3,–4), and one that passes through (2,3), (3,4), and (6,7).
