Version History of Provinces 2015 (1:4 500 000) Dataset
The 'History' table is an integral part of a dataset collection, providing a comprehensive historical record of its base table rows. This history table originates from 'Tilastokeskus' (Statistics Finland) and is designed to track the changes in the data over time. It is especially useful in maintaining the integrity of the data and in facilitating data analytics that take into account the temporal aspect of the data.
The table is enriched with a variety of columns. Unique identifiers for each row are formed by a combination of a start date and a row number, which help track the sequence and time frame of the data's extraction. This is further enhanced with an end date, indicating when a new version of the row was extracted from the source. If the end date is null, it signifies that the row is the most recent version.
A particularly interesting aspect of this table is the inclusion of geospatial data. Several columns starting with 'geom_' contain geographic information, providing rich resources for geospatial data analytics. These geographic coordinates are represented using the WGS 84 coordinate reference system, where the axis order is longitude first, followed by latitude.
The base table contents, translated as 'Regions 2015 (1:4 500 000)', provide a snapshot of regional data, including various geographic attributes. These attributes include, for example, the names of regions in different languages.
Given the rich historical and geospatial data, this table can be utilized in various ways in data analytics. For instance, one could track the changes in regional boundaries over time or analyze the growth patterns of different regions. Furthermore, combining this data with other socio-economic indicators, one could study the impact of geographical factors on social or economic developments.
Field Descriptions
Name | Data type | Description |
---|---|---|
_start_date | date | This column contains the date when the respective row was extracted from the data source. It is part of a unique combination with '_row_number' that identifies each row in the version history table. |
_end_date | date | This column records the date when a new version of the row was extracted from the data source. A null value in this column indicates that the row is the most recent version. |
_row_number | long | This column contains the number of the row in the raw data extracted from the data source. It forms a unique identifier for each row in combination with '_start_date'. |
geom_geojson | string | This column contains geometric data in GeoJSON format, which can represent a variety of geographic data structures. |
geom_geotext | string | This column stores the geometric data as a text string, which can represent various geographic data structures. |
geom_type | string | This column specifies the type of geometric data structure represented in the 'geom_geojson' and 'geom_geotext' columns. |
geom_centroid | string | This column contains the centroid of the geometric shape represented by the 'geom_geojson' and 'geom_geotext' columns. |
geom_center_x | double | This column represents the X coordinate of the center of the geometric shape. |
geom_center_y | double | This column represents the Y coordinate of the center of the geometric shape. |
gml_id | string | This is a unique identifier for each row in the table. |
