Swedish Land Survey Data: Changes in Geospatial Attributes
Click here for a data sample
The 'cha_62fno' table is a detailed collection of geographic and related data, meticulously sourced from the 'Lantmäteriet' website in Sweden. The table features a multitude of columns that contain diverse information, all organized in a structured manner. Two key columns in this table include the extract date and the row number, both of which work in tandem to uniquely identify each row of data. This allows for precise tracking of data extraction and its source row, providing a reliable reference point for any subsequent data analysis. The table also encompasses geographic data transformed from shapefile format, a common format for storing geometric location and attribute information. This implies that the data stored can include a variety of geographic features represented by points, lines, or polygons. The table is part of a larger dataset collection, further adding to its value in terms of data depth and potential usage. Being a rich reservoir of geographic and related data, this table could prove immensely valuable in data analytics; for instance, it could be used to study changes in geographic features over time, to analyze geographic patterns in relation to other variables in the table, or even to create complex geographic information system (GIS) models.
