| SamplingFeatures | Describes the sampling features on which observations are made. |
| Columns | |||||||
| PK | Name | Data Type | NULLs | A/N | Default | Comment | FK |
|
| SamplingFeatureID | Integer |
| Primary key identifier. | |||
| SamplingFeatureUUID | UniqueID | A universally unique identifier for the sampling feature. | |||||
| SamplingFeatureTypeCV | VarChar(255) | CV term descripting the type of sampling feature. |
|
||||
| SamplingFeatureCode | VarChar(50) | A short but meaningful text identifier for the sampling feature. | |||||
| SamplingFeatureName | VarChar(255) |
| Sampling Feature name (free text). | ||||
| SamplingFeatureDescription | VarChar(5000) |
| Text describing the sampling feature. | ||||
| SamplingFeatureGeotypeCV | VarChar(255) |
| Dimensionality of SamplingFeature; point2d, line2d, etc. |
|
|||
| FeatureGeometry | Geometry |
| The location geometry of the sampling feature on the Earth expressed using a geometry data type. Can be a Point, Curve (profile, trajectory, etc), Surface (flat polygons, etc) or Solid/Volume (although often limited to 2D geometries). | ||||
| FeatureGeometryWKT | VarChar(8000) |
| The location geometry of the sampling feature on the Earth expressed as well known text (WKT). Can be a Point, Curve (profile, trajectory, etc.), Surface (flat polygons, etc.), or Solid/Volume (although often limited to 2D geometries). | ||||
| Elevation_m | Float |
| The elevation of the sampling feature in meters, or in the case of Specimen, the elevation from where the SamplingFeature.Specimen was collected | ||||
| ElevationDatumCV | VarChar(255) |
| The code for the vertical geodetic datum that specifies the zero point for the Sampling Feature Elevation. |
