The table under discussion is a historical table, sourced from the Swedish website 'Lantmäteriet'. It is part of a larger dataset collection and holds a record of version history for its base table rows. This table is unique in its structure as it includes two additional columns compared to its base table, which log the start and end dates of data extraction from the source. The start date and row number together provide a unique identifier for each row in this history table. If an end date is absent, it indicates that the particular row represents the most recent version.

The data within this table is geographically oriented and originally stored in shapefile format. This format is a non-topological method for storing geometric location and attribute information of geographic features, which can exist as points, lines, or polygons. The geographic data in this table has been converted from the shapefile format to its final format.

As for usage in data analytics, this table could provide valuable insights in several ways. For instance, tracking changes in geographic features over time could aid in studying environmental changes. The start and end dates could also be used to analyze the frequency of updates or changes in the data source. Furthermore, the unique combination of the start date and row number could be used to track specific data rows and their evolution over time.

Field Descriptions

Name Data type Description
_start_datedateThis column records the date when the row was extracted from the data source. It forms a unique combination with the '_row_number' column to identify each row in this version history table.
_end_datedateThe '_end_date' column contains the date when a new version of the row was extracted from the data source. A null value in this column signifies that the row is the most recent version.
_row_numberlongThe '_row_number' column contains the number of the row as it is in the raw data extracted from the data source. It forms a unique combination with the '_start_date' column to identify each row in this version history table.
OBJECTIDlongThe 'OBJECTID' column stores the unique identifier for each object in the table.
IDstringThe 'ID' column stores the unique identification number for each record in the table.
CODE_12stringThe 'CODE_12' column holds a specific code related to each record in the table.
Area_HadoubleThe 'Area_Ha' column contains the area of the record in hectares.
RemarkstringThe 'Remark' column stores any additional comments or notes related to each record in the table.
Shape_LengdoubleThe 'Shape_Leng' column contains the length of the shape of the record.
Shape_AreadoubleThe 'Shape_Area' column contains the area of the shape of the record.
geom_geojsonstringThe 'geom_geojson' column stores the geometric representation of the record in GeoJSON format.
geom_geotextstringThe 'geom_geotext' column stores the geometric representation of the record in textual format.
geom_typestringThe 'geom_type' column indicates the geometric type of the record.
geom_centroidstringThe 'geom_centroid' column contains the centroid of the geometric representation of the record.
geom_center_xdoubleThe 'geom_center_x' column contains the x-coordinate of the center of the geometric representation of the record.
geom_center_ydoubleThe 'geom_center_y' column contains the y-coordinate of the center of the geometric representation of the record.
