The table in question is a historical data collection, found within the 'norrbotten' dataset. It serves as a comprehensive record of the version history of its base table rows. This aspect of the table is showcased through two additional columns that record the start and end dates of each row's extraction from the data source. A unique identifier for each row is generated through a combination of its start date and its row number.

This table also includes a geographic component. The geographic data is stored in shapefile format, a widely used format for storing the geometric location and attribute information of geographic features. The geographic features in this dataset can be points, lines, or polygons (areas). This data has been transformed from its original shapefile format into the final geographic format.

The table's data is sourced from the 'Lantmäteriet' website, based in Sweden.

From a data analytics perspective, this table could be used in a variety of ways. For example, its temporal data could be utilized to track changes in the dataset over time, providing valuable insights into trends and patterns. The geographic data, meanwhile, could be used in spatial analysis, contributing to studies in fields like environmental science, urban planning, or transportation logistics. Furthermore, the unique identifiers for each row allow for precise tracking and analysis of specific data points across different versions.

Field Descriptions

Name Data type Description
_start_datedateThis column contains the date when the row was extracted from the data source. Together with '_row_number', it forms a unique identifier for each row in this version history table.
_end_datedateThis column contains the date when a new version of the row was extracted from the data source. If the value is null, it indicates that the row is the most recent version.
_row_numberlongThis column shows the number of the row in the raw data extracted from the data source. It forms a unique identifier for each row in conjunction with '_start_date'.
OBJECTIDlongThis column contains the identification number of the object.
IDstringThis column contains the identification number.
CODE_12stringThis column contains a 12-digit code associated with the data.
Area_HadoubleThis column represents the area of the object in hectares.
RemarkstringThis column contains any remarks or comments related to the data.
Shape_LengdoubleThis column contains the length of the shape.
Shape_AreadoubleThis column contains the area of the shape.
geom_geojsonstringThis column contains the geometric data of the object in GeoJSON format.
geom_geotextstringThis column contains the geometric data of the object in text format.
geom_typestringThis column specifies the type of the geometric shape of the object.
geom_centroidstringThis column contains the centroid of the geometric shape of the object.
geom_center_xdoubleThis column contains the X coordinate of the geometric center of the object.
geom_center_ydoubleThis column contains the Y coordinate of the geometric center of the object.
