Geospatial Data and Properties of Land Cover in Norrbotten
Click here for a data sample
The table is a part of a dataset collection from Lantmäteriet (The Land Survey) in Sweden. It consists of several columns, each representing different types of data related to geographical features. Two special columns contain the date of data extraction and the unique row number, respectively. Together, these columns provide a unique identifier for each row in the table. The geographic information, originally in shapefile format, has been transformed into a final format suitable for this dataset. The table includes detailed information about the area in hectares, the geometry of the location, and certain identification codes. Furthermore, it contains data about the geometric center of the geographical feature, both in terms of coordinates and as a text description. The data in this table can be used for various analytical purposes. For instance, it could be used to analyze land use patterns over time, given the date of data extraction. The data could also be utilized in environmental studies to understand the distribution of different geographical features, or in urban planning to map out the expansion of urban areas.
