Grid and Frame Data with Geometric Attributes for Maps of Sweden
The 'rutnat' table is a collection of geographic data that has been transformed from the shapefile format. Located within the dataset collection from 'Lantmäteriet' in Sweden, this table consists of several columns. The combination of the extract date and row number columns uniquely identifies each row of data. This unique identifier traces back to the original date of data extraction and the row number from the source data. The table also contains geographic attributes such as the type of geometry, the geographic center, and centroid, which provide detailed spatial information of the data.
The data in the table can have multiple applications in data analytics. For instance, the geographic features can help in spatial analysis or mapping coordinates for various purposes. The unique identification of each row, combined with the date of extraction, can be used to track changes over time, identifying patterns or anomalies. Furthermore, the table can also support complex queries for researchers interested in geographic information systems (GIS) studies. For example, the data can be used to analyze the patterns of certain geographic features over time or to study the spatial distribution of these features.
Field Descriptions
| Name | Data type | Description |
|---|---|---|
| _extract_date | date | This column records the date when the data was extracted from the Lantmäteriet (Swedish Mapping, Cadastral and Land Registration Authority) source for each row. It provides a timestamp that can help track changes over time. |
| _row_number | long | This column assigns a unique row number to each piece of data extracted from the source on a specific extract date. When used in conjunction with the '_extract_date' column, it can uniquely identify each row. |
| KKOD | string | This column contains the category code for each row of data. This code can provide information about the type or category of the data in the row. |
| geom_geojson | string | This column contains the geography of the data in GeoJSON format. This format provides geographic data in a text-based format that includes coordinates and other geographic information. |
| geom_geotext | string | This column provides geographic data in a text format. This can include coordinates and other geographic information in a text-based format. |
| geom_type | string | This column specifies the type of geometry for each row of data. This can provide information about whether the data represents a point, line, polygon, or another type of geographic feature. |
| geom_centroid | string | This column contains the geographic centroid for each row of data. The centroid is the geometric center of a shape, providing a single point that can be used to represent the overall location of the geographic feature. |
| geom_center_x | double | This column contains the x-coordinate of the geographic center for each row of data. This can provide a precise location in a geographic coordinate system. |
| geom_center_y | double | This column contains the y-coordinate of the geographic center for each row of data. Combined with the 'geom_center_x' column, this provides a precise location in a geographic coordinate system. |
