2023 Geospatial Data of Postal Code Areas Extending to Sea Zones

The table in focus forms part of a group of related data tables, specifically belonging to the 'postialue_pno_meri_2023' dataset collection. The table’s contents revolve around the Paavo postal code areas (extending to maritime areas) for the year 2023, sourced from Finland's 'Tilastokeskus' (Statistics Finland) website.

The data in the table is organized into various columns, which include unique identifiers, geographic information, and other specific details. Two of these columns are '_extract_date' and '_row_number'. The '_extract_date' column denotes the date on which the data row was extracted from the source, while the '_row_number' column indicates the row number in the data extracted from the source on the specified extract date. Together, these two columns uniquely identify each row in the table.

The table also contains columns starting with 'geom_', which house geographic information relevant for geospatial data analytics. These geographic coordinates are presented using the WGS 84 coordinate reference system, with the axis order being longitude first, followed by latitude.

In terms of data analytics, this table provides a rich source of information. For instance, analysts can use the geographic coordinates and area details to study population distribution patterns across different postal code areas. Additionally, they can track changes over time by comparing the data extraction dates. Furthermore, the unique identifiers in the table can be instrumental in merging this data with other datasets, thereby enriching the overall analysis and leading to more comprehensive insights.
