The fields with this property are optimized for geospatial (distance and location) operations. For a particular field property, you set GeospatialType
to specify whether you store the location data in a single field or in multiple fields, and if you use multiple fields, which dimension the field property represents.
You can use the following values:
Unified. The fields with this property store unified location information. In this case, the associated fields store the location data in a single field, as either a POINT or POLYGON definition in Well-known text format. For example, POINT (x y)
or POLYGON ((x0 y0, x1 y1, ..., xN yN))
.
NOTE: If you use longitude and latitude values, you must still specify points in the order x y (that is, longitude then latitude).
For polygon definitions, you specify an X/Y pair of coordinates for each vertex of the polygon, working either clockwise or anti-clockwise around the polygon. The polygon can be concave, but the edges cannot cross themselves. The polygon can contain holes. For example, the following field defines a polygon with one hole:
#DREFIELD SHAPE="POLYGON((35 10, 45 45, 15 40, 10 20, 35 10),(20 30, 35 35, 30 20, 20 30))"
X. The fields with this property store the x-coordinate for Cartesian coordinates. In this case, the associated fields store a single value that represents the coordinate.
Longitude. The fields with this property store the Longitude value for spherical coordinates. In this case, the associated fields store a single value that represents the coordinate.
Y. The fields with this property store the y-coordinate for Cartesian coordinates. In this case, the associated fields store a single value that represents the coordinate.
Latitude. The fields with this property store the Latitude value for spherical coordinates. In this case, the associated fields store a single value that represents the coordinate.
NOTE: IDOL Server treats the X and Longitude types as equivalent, and similarly treats the Y and Latitude types as equivalent.
