Bracketed terms represent the field name.
Area of the geomark in hectares.
KML text that specifies geometry or geometries of a geomark.
The western, southern, eastern, and northern extent of the geomark displayed in geographic coordinates. Western and eastern extent are displayed as decimal degrees of longitude. Northern and southern extent are displayed as decimal degrees of latitude.
The style of buffer to use at each end of a buffered line (e.g., round, square, flat).
The style of buffer to use for joins between the line segments for lines and polygons (e.g., round, mitre,bevel).
The number of line segments used in each quadrant to approximate the curve for round end-cap and join styles. Must be a positive number.
The amount to buffer the geometry (in metres). Must be a positive integer (e.g., 10). If left blank, no buffer will be added to input geometries and points and lines will stay points and lines. If a buffer is specified, point and line inputs will become polygons.
The latitude and longitude of a point at or near the centre of a geomark or, if the centre is outside the polygon, some point guaranteed to be inside the polygon.
The date geomark was created.
The date a geomark expires. Once expired, it will no longer be accessible. If a geomark is in use by a government application, it will never expire until it is no longer required by that application.
A unique, immutable, and meaningless identifier assigned to the geomark.
The number of geometries in the geomark. If you select One, the first geometry in a feature, feature collection or geometry collection will be used. If you select Many, all geometries of the selected geometry type will be used. Multiple geometries, buffered or not, can’t overlap. (1mm tolerance)
Type of input geometry. Valids types are Point, Line, Polygon, Any.
A geometry that has a minimum clearance of less than one millimetre is not robust. Minimum clearance is the shortest distance between any two points or between a line and a point in the geometry. A geometry that is not robust will self-intersect when loaded into a spatial data store or application. For more info, see Interchange of Spatial Data – Inhibiting Factors (PDF)
A simple geometry is closed and doesn’t self-intersect or have self-tangent points. For more info, see the Simple Feature Access - Part 2: SQL Option
A geometry is valid if it meets the validity conditions for the given geometry type. For example, a linear ring must be simple. A polygon must consist of one outer boundary and zero or more inner boundaries, all of which must be simple. All inner boundaries must be contained within the outer boundary without touching. For more info, see ST_IsValid - PostGIS
Length of the geomark in kilometers.
Number of vertices in all polygon boundaries of the geomark. A polygon without holes has a single, outer boundary, a polygon with one hole has one outer boundary and one inner boundary.
Detailed validation error message if geometry is not valid; blank otherwise.
