Geospatial Objects¶
Points¶
A point can be any record that has fields containing the longitude and latitude of a geospatial point.
Shapes¶
Kinetica supports the following WKT types: Point, LineString, Polygon, MultiPoint, MultiLine, MultiPolygon, and GeometryCollection. Examples of WKT include:
POINT (1 1)
MULTILINESTRING ((1 1, 2 2, 3 3),(-3 -3, -2 -2, -1 -1, 0 0))
GEOMETRYCOLLECTION(POINT(4 6),LINESTRING(4 6,7 10))
Tracks¶
Tracks are a collection of points which represent the path an object takes across the map. Unlike a WKT multiline string, each point in a track has an associated timestamp. Taken together: the longitude, latitude, and timestamp in each record describe where the object was at a given time; all points in a given track should contain the same track ID. Tables containing tracks must have columns of the following names and types (names are case-sensitive):
TRACKID- unrestricted stringx- any numeric type (int, float, double, etc.)y- any numeric type (int, float, double, etc.)TIMESTAMP- any numeric or time-based type (long, datetime, etc.)
Tracks can be accessed via the following endpoints:
Important
Join views cannot be used to render tracks.
Labels¶
Labels are text labels located at specified positions on the map. Each label can optionally be enclosed in a box and can have a line pointing to a specific location.
