Land Cover Classification Data with Geometric Properties and Extraction Details
Click here for a data sample
The table is a comprehensive data collection from the 'Lantmäteriet' (The Land Survey) in Sweden. It contains a rich array of data that has been extracted and transformed from a shapefile format, which is a common type of format for storing the geometric location and attribute information of geographic features. It includes unique identifiers for each row, provided by a combination of the extraction date and the row number. The table also includes geographical data such as the object ID and the specific area in hectares. There are also specific code identifiers, geometrical data in geojson and geotext formats, as well as the geometric type, centroid, and center coordinates. This dataset can provide valuable insights for data analytics, particularly for geographical studies and land use planning. For example, the data could be used to analyze the distribution and variation of land areas over time, to study the spatial distribution of certain geographical features, or to plan land use based on the geographical data provided.

Data type |
Description |
| _extract_date | date | This is a special column that contains the date when the data in the row of the table was extracted from the data source. It helps to keep track of when the data was updated or added. |
|---|
| _row_number | long | Another special column that contains the row number in the data extracted from the source on the extract date specified by the column '_extract_date'. It aids in identifying each row uniquely. |
|---|
| OBJECTID | long | This column holds unique identifiers for each object in the table. |
|---|
| ID | string | This column contains an identification code for each entry, prefixed with 'SE_' indicating data relevant to Sweden. |
|---|
| CODE_12 | string | This column carries specific codes associated with each entry, possibly representing a categorization or classification. |
|---|
| Area_Ha | double | This column represents the area of the object in hectares. It provides geographical information about the size of the object. |
|---|
| Remark | string | This column is intended for any notes or comments related to the respective row's data. |
|---|
| Shape_Leng | double | This column might contain the length of the shape representing the geographical object, however, no sample data is provided. |
|---|
| Shape_Area | double | This column indicates the area of the shape representing the geographical object, providing more detailed geographical information. |
|---|
| geom_geojson | string | This column contains the geographical data related to the object in GeoJSON format, a popular open standard format designed for representing simple geographical features. |
|---|
| geom_geotext | string | This column contains the geographical data in a text-based format, possibly representing the coordinates of the object. |
|---|
| geom_type | string | This column indicates the type of the geographical object represented in the 'geom_geotext' and 'geom_geojson' columns. |
|---|
| geom_centroid | string | This column holds the coordinates for the centroid or geometric center of the object. This aids in understanding the central location of the object. |
|---|
| geom_center_x | double | This column contains the x-coordinate (longitude) of the object's center. |
|---|
| geom_center_y | double | This column contains the y-coordinate (latitude) of the object's center. |
|---|
