Version History Records of Geographical Features from a Swedish Dataset Collection
The table under discussion is a history table, sourced from the 'Lantmäteriet' website in Sweden. It is part of a larger dataset collection and maintains a version history of its base table rows. The table is unique for its incorporation of time-stamped data extraction information, allowing users to track changes over time. For instance, one can identify when a particular row was extracted from the data source and when a new version of the same row was sourced. If there is no end date for a row, it signifies that the row is the most recent version.
The table also has a unique feature of maintaining a row number, which together with the start date, serves as a unique identifier for each row in this version history table. This allows for easy referencing and tracking of specific data points within the table.
Apart from these, the table holds geographical information derived from the shapefile format, a common format for storing the geometric location and attribute information of geographic features. The geographic features can be represented by points, lines, or polygons (areas).
In terms of data analytics, this table provides a rich source of historical and geographical data. For instance, analysts could use the time-stamped data to track and analyze changes in geographic features over time, such as land use changes, urban sprawl, or vegetation growth. The geographic information could be used for spatial analysis, including the study of patterns, relationships, and trends within geographic data. Furthermore, the table's structure allows for version control, enabling analysts to compare different versions of the same data and understand how it has evolved over time.
Field Descriptions
Name | Data type | Description |
---|---|---|
_start_date | date | This column contains the date when the row was extracted from the data source. Together with '_row_number', this column helps in uniquely identifying each row in this version history table. |
_end_date | date | This column contains the date when a new version of the row was extracted from the data source. If the value is null, it signifies 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 pair with '_start_date' to identify each row in this history table. |
OBJECTID | long | This is a column with unspecified content. It may hold unique identifiers for each row or other data. |
ID | string | This is a column with unspecified content. It could be used for storing identification data. |
CODE_12 | string | This is a column with unspecified content. It could be storing a specific code or tag associated with each row. |
Area_Ha | double | This is a column with unspecified content. It may contain area measurements in hectares or other related data. |
Remark | string | This is a column with unspecified content. It could be used for storing additional comments or remarks about each row. |
Shape_Leng | double | This is a column with unspecified content. It may contain data concerning the length of a shape or object. |
Shape_Area | double | This is a column with unspecified content. It may contain data concerning the area of a shape or object. |
geom_geojson | string | This is a column with unspecified content. It likely contains geographical data in GeoJSON format. |
geom_geotext | string | This is a column with unspecified content. It could be storing geographical data in a textual format. |
geom_type | string | This is a column with unspecified content. It likely specifies the type of geographical data stored in the row. |
geom_centroid | string | This is a column with unspecified content. It likely contains data regarding the centroid of a geographical feature. |
geom_center_x | double | This is a column with unspecified content. It could be storing the X-coordinate of a geographical feature's center. |
geom_center_y | double | This is a column with unspecified content. It could be storing the Y-coordinate of a geographical feature's center. |
