 | Commentary |This field helps to differentiate between vector (Point, Line, Polygon), raster (Raster, Image), nonspatial formats (table), or a combination (Mixed). If processing metadata from a geospatial web server, this value may be programmatically determined. However, in many cases, it must be manually determined. The field is tied to icons for the resource, and provides the user with visual clues to the item. However, if the element is troublesome or unnecessary for a particular institution, it can be omitted.|
