# Supported Well-Known Text Geometric Objects

Geometric objects such as points, lines, and polygons can be represented as text using the Well-Known Text (WKT) format. IDOL supports the following WKT geometric objects. You can use these in unified geospatial document fields and in queries against those fields (for example, see the GEOCONTAINS, GEOINTERSECTS, and GEOWITHIN field specifiers).

Geometric Object | Description
--- | ---
POINT | A point. You specify a single pair of coordinates. `POINT(X1 Y1)`
LINESTRING | A line, or a line with multiple segments. You specify at least two pairs of coordinates. To construct a `LINESTRING` with multiple segments, specify more than two pairs of coordinates. `LINESTRING(X1 Y1, X2 Y2, ...)`
POLYGON | A polygon. You specify a pair of coordinates for each vertex, working either clockwise or counterclockwise around the polygon. The polygon can be concave, but the edges cannot cross themselves. `POLYGON((X1 Y1, X2 Y2, ...))` A polygon can also contain holes, defined by further groups of coordinates. `POLYGON((X1 Y1, X2 Y2, ...), (X1 Y1, X2 Y2, ...))`
MUTLIPOINT | A collection of points. `MULTIPOINT (X1 Y1, X2 Y2, ...)`
MULTILINESTRING | A collection of lines. `MULTILINESTRING ((X1 Y1, X2 Y2, ...), (X1 Y1, X2 Y2, ...))`
MULTIPOLYGON | A collection of polygons. `MULTIPOLYGON (((X1 Y1, X2 Y2, ...)), ((X1 Y1, X2 Y2, ...)))`
GEOMETRYCOLLECTION | A collection of other WKT objects. `GEOMETRYCOLLECTION(POINT(X1 Y1), LINESTRING(X1 Y1, X2 Y2, ...), POLYGON((X1 Y1, X2 Y2, ...)))` You cannot include a GEOMETRYCOLLECTION within a GEOMETRYCOLLECTION.

NOTE: If you use longitude and latitude values, you must still specify points in the order x y (that is, longitude then latitude).
