geospatial: Geospatial Datatype designer

In baasman/allegRo: This package provides an interface for interacting with an Allegro Graph server

Description

See official AllegroGraph documentation for information on 2D and nD Geospatial database design. See examples below to get a general idea on how to use these functions.

Usage

listGeoTypes(repository)

getCartesianGeoType(repository, stripWidth = NULL, xMin = NULL,
  xMax = NULL, yMin = NULL, yMax = NULL)

getSphericalGeoType(repository, stripWidth = NULL, unit = "degree",
  latMin = NULL, latMax = NULL, longMin = NULL, longMax = NULL)

getStatementsInsideBox(repository, type, predicate, xMin, xMax, yMin, yMax,
  limit = NULL)

getStatementInsideCircle(repository, type, predicate, x, y, radius,
  limit = NULL, offset = NULL)

getStatementsHaversine(repository, type, predicate, lat, long, radius,
  radiusUnit = "km", limit = NULL, offset = NULL)

createPolygon(repository, resource, points)

getStatementsInsidePolygon(repository, type, predicate, polygon, limit = NULL,
  offset = NULL)

Arguments

repository	Object of type repository specifying server details and repository to work on.
stripWidth	Determines the granularity of the strip.
xMin	Helps determine size of cartesian plane
xMax	Helps determine size of cartesian plane
yMin	Helps determine size of cartesian plane
yMax	Helps determine size of cartesian plane
unit	Defaults to 'degree'. The unit in which stripWidth is specified. It can be degree, km, radian or mile.
latMin	Limit the size of the region modelled by appropriate type
latMax	Limit the size of the region modelled by appropriate type
longMin	Limit the size of the region modelled by appropriate type
longMax	Limit the size of the region modelled by appropriate type
type	Specifies a geospatial sub-type, as created by getCartesianGeoType or getSphericalGeoType
predicate	Specifies a predicate for the query
limit	Specifies a maximum number of triples to return
x	Specifies x-coordinate of circle
y	Specifies y-coordinate of circle
radius	Specifies the radius of the circle
offset	Specifies how many triples should be skipped over
lat	Specifies the latitude of the center of the circle
long	Specifies the longitude of the center of the circle
radiusUnit	Defaults to km. Spefies the unit in which radius is given when using Haversine
resource	Name of the polygon to add
points	A list of points represented as AllegroGraph geospatial object (created through createCartesianGeoLiteral)
useContext	When true (default false), use the context (graph) field of the triple instead of its object
