Vertica Analytics Platform Version 10.1.x Documentation

Geospatial Analytics

Vertica provides functions that allows you to manipulate complex two- and three-dimensional spatial objects. These functions follow the Open Geospatial Consortium (OGC) standards. Vertica also provides data types and SQL functions that allow you to specify and store spatial objects in a database according to OGC standards.

Convert Well-Known Text (WKT) and Well-Known Binary (WKB)

Convert WKT and WKB.

Optimized Spatial Joins

Perform fast spatial joins using ST_Intersects and STV_Intersects.

Load and Export Spatial Data From Shapefiles

Easily load and export shapefiles.

Store and Retrieve Objects

Determine if:

  • An object contains self-intersection or self-tangency points.
  • One object is entirely within another object, such as a point within a polygon.

Test the relationships between objects

For example, if they intersect or touch:

  • Identify the boundary of an object.
  • Identify vertices of an object.

Calculate

  • Shortest distance between two objects.
  • Size of an object (length, area).
  • Centroid for one or more objects.
  • Buffer around one or more objects.
