Gradnat Table: Degree Line and Arctic Circle Layer Information from Sweden's Geographical Dataset Collection
The 'gradnat' table is part of a geographic dataset collection, sourced from the Swedish National Land Survey (Lantmäteriet) website in Sweden. The table stores geographic information, such as geographic graticule and the Arctic Circle, as well as the degree line. The information is organized in a tabular format that allows for efficient data analysis and access.
Each row in the table represents a unique geographic feature, identified by a combination of extraction date and row number. This ensures that every geographic feature in the table can be distinctly recognized.
The table contains detailed geographic information, including the type of geographic feature it represents, the geographic coordinate where it is located, and its geometric shape and properties. All these geographic attributes are stored in a format that can be easily understood and processed by geographic information systems (GIS).
In addition to geographic information, the table also contains an attribute that categorizes the geographic feature. This attribute can be used to filter and group the data during analysis.
In terms of data analytics, the information in this table can be used in a variety of ways. For instance, it can be used to analyze the geographic distribution of various features, such as the Arctic Circle and degree lines. This could be beneficial for researchers studying climate change or geologists studying the earth's features. It can also be used to create detailed maps of these features, which could be useful for navigation or exploration purposes.
Furthermore, the time-stamped data allows for the study of changes over time. This could be used to track changes in the geographic features, which could be indicative of larger environmental trends.
Field Descriptions
| Name | Data type | Description |
|---|---|---|
| _extract_date | date | This column contains the date when the data on the row of the table was extracted from the source. It is one of the special columns that helps in uniquely identifying each row of data. |
| _row_number | long | This is another special column which specifies the row number in the data extracted from the source on the respective extract date. This column in combination with the '_extract_date' column helps in uniquely identifying each row of data. |
| KKOD | string | This column represents the category code associated with the geographic feature in the dataset. It is a key field that links the geographic data with its symbolic representation. |
| geom_geojson | string | This column contains the geometric data for the geographic feature in GeoJSON format. GeoJSON is an open standard format designed for representing simple geographical features, along with their non-spatial attributes. |
| geom_geotext | string | This column stores the geometric data for the geographic feature in a human-readable text format. It provides an easy way to visualize the geographical features represented in the data. |
| geom_type | string | This column specifies the type of the geometric data stored in the 'geom_geojson' and 'geom_geotext' columns. For example, it indicates whether the geographic feature is a point, line, or polygon. |
| geom_centroid | string | This column contains the geometric center (or centroid) of the geographic feature. The centroid is the average position of all the points in the shape, and it can be useful for determining the relative position of the feature. |
| geom_center_x | double | This column represents the x-coordinate of the geometric center of the geographic feature. It is part of the data used to locate the feature on a map. |
| geom_center_y | double | This column represents the y-coordinate of the geometric center of the geographic feature. Like the 'geom_center_x' column, it is part of the data used to locate the feature on a map. |
