Data Field
A column in a data table representing a specific attribute, essential for organizing and analysing spatial data.
What does a Data Field represent?
Usually arranged as a column in a table or database, a data field denotes a particular kind of information or attribute found in a dataset. Values about a single attribute or property of the records (or features), such as names, numbers, categories, or measures, are contained in each field.
For each geographic feature in a Geographic Information System (GIS), a data field in an attribute table may hold data such as population, elevation, land use type, or area size. For instance, the lake name, depth, water quality rating, and surface size might all be data fields in a lake dataset. A lake is represented by each row (or record) in the table, and a specific piece of information about it is contained in each column (or field).
Data fields are essential for structuring and organizing data so that it may be efficiently stored, queried, analysed, and visualized for a variety of applications.
