Geospatial Data Analysis: Detailed Land Mapping and Attribute Information
Click here for a data sample
The table in question is a part of a larger dataset collection, sourced from the Swedish website, 'Lantmäteriet'. This table is unique in its composition, containing a myriad of columns with a special emphasis on two particular ones: one that denotes the date of data extraction and another that indicates the row number in the extracted data. These two columns work together to uniquely identify each row in the table. The table's data format is noteworthy, as it originates from a geometric location and attribute information storage format known as shapefile. This format is typically used for storing geographic features, which can be represented as points, lines or polygons. In this dataset, the original shapefile format has been transformed into the final geographic format. The data in this table could be instrumental in data analytics in several ways. For instance, the unique identifiers could be used to track changes in the data over time, providing valuable insights into temporal trends. The geographic information could be utilized in spatial analyses, potentially aiding in tasks such as land use planning or environmental impact assessments. Furthermore, the extraction date could be used to monitor the frequency and timing of data updates, which could be crucial in maintaining the accuracy and relevancy of analyses.
Field Descriptions
Name |
Data type |
Description |
_extract_date | date | This is a special column that records the date when the data on the row of the table was extracted from the source. The format of the date is YYYY-MM-DD. |
_row_number | long | This is a special column that represents the row number in the data extracted from the source on the extract date specified by the '_extract_date' column. It serves as part of the unique identifier for each row in conjunction with '_extract_date'. |
OBJECTID | long | This column stores the unique identifier for each object in the data. |
ID | string | This column contains an identification number assigned to each row. |
CODE_12 | string | This column contains the 12-digit code associated with each row. |
Area_Ha | double | This column measures the area of the geometric object in hectares. |
Remark | string | This column includes any additional comments or remarks related to the row. |
Shape_Leng | double | This column contains the length of the geometric shape associated with each row. |
Shape_Area | double | This column represents the area of the geometric shape associated with each row. |
geom_geojson | string | This column stores the geometric data of objects in a GeoJSON format, which is a format for encoding a variety of geographic data structures. |
geom_geotext | string | This column stores the geometric data of objects in a textual format. |
geom_type | string | This column indicates the type of the geometric object (e.g., point, line, polygon). |
geom_centroid | string | This column represents the centroid of the geometric object. The centroid is the geometric center of a plane figure or shape. |
geom_center_x | double | This column represents the X coordinate of the geometric center or centroid of the object. |
geom_center_y | double | This column represents the Y coordinate of the geometric center or centroid of the object. |
