Geographical and Geometrical Data Collection for Land Survey Analysis
Click here for a data sample
The table in question is a geographically rich dataset that originates from 'Lantmäteriet' (The Land Survey) in Sweden. It contains a variety of columns that store data extracted from a data source, each identified uniquely by a combination of extraction date and row number. The geographic information it holds, initially in shapefile format, has been transformed into a final geographic format, allowing it to represent geographic features as points, lines, or polygons (areas). This dataset offers a plethora of possibilities for data analytics. For instance, you could use the geographic data to analyze spatial patterns, trends, or anomalies over time, or make use of the extraction date and row number to track changes in the dataset or identify discrepancies. The table's detailed geographic data could also be utilized to visualize and explore the geographic distribution of features or phenomena that the dataset represents.
