Specifies a GEOGRAPHY column for the geospatial data. The whole file or the whole tableĬorresponds to the feature collection. Usually corresponds to the spatial feature. To describe a spatial feature, WKT is usually embedded in a container fileįormat, such as a CSV file, or in a database table. WKB can be hex encoded for formats thatįor example, the following defines a point in WKT: POINT(-121 41) Polygons with optional holes, or a collection of points, lines, or polygons. Text format for describing individual geometry shapes using points, lines, Single points on Earth can be described by just a longitude, latitude pair.įor example, you can load a CSV file that contains longitude and latitude valuesįunction to convert them into GEOGRAPHY values.įor more complex geographies, you can load the following geospatial data formats Point set is a set of points, lines, and polygons on the The GEOGRAPHY data type describes a point set on the Earth's surface. Each row of the table is a spatialįeature, and the entire table represents a spatial feature collection. Spatial features, create a table with a GEOGRAPHY column for the geometry plusĪdditional columns for the attributes. A spatial feature collection is a set of spatial features.ĭata type represents a geometry value or geometry collection.Geometry with additional attributes that are application-specific. A spatial feature represents a logical spatial object.Using points, lines, polygons, or a collection of points, lines, and polygons.Ī geometry collection is a geometry that represents the spatial union of all A geometry represents a surface area on the Earth.Geographic data is also known as geospatial data.Ĭommon types of objects when working with geospatial data include the following: Geospatial analytics let you analyze geographic data inīigQuery.
