DEPARTMENT OF MINES AND PETROLEUM Spatial Data Infrastructure Data Dictionary for Feature Classes 1:500K Tectonic units of Western Australia Version 1.0 19/02/2016 12:32:42 PM Page 1 of 4 Data dictionary In Geographic Information Systems (GIS), data dictionaries are used as a means to record the names of the attributes (items) in a feature class, together with a description of the attribute values, and lookup tables, for which a data dictionary has been provided. Data dictionary table contains the following information: file name, feature category, feature class, spatial type, description, item name, key, option, type, width and item description. For item type, a code is used to describe the field type: C = Character field D = Date field N = Number field For Key, a code is used to indicate whether the item or field is a key used to link to tables: P = Primary key F = Foreign key Null = Not a key For Optional, a code is used to indicate whether the items or fields that may or may not be provided: Y = Optional Null = Not optional A user can view the attribute table of a theme as described in the data dictionary listing at the beginning of this document and see the item names along with the data type and description. When a user views the attribute table, the user will see the item names described in the data dictionary, and their contents. The user will also see several items that are standard to ESRI ArcSDE feature classes. These standard (internal) items have been omitted from the enclosed data dictionary descriptions for ease of reading. The omitted items are as follows: Item names Type Item description OBJECTID N Unique identifier for each object in the feature class SHAPE C Geometry type SHAPE.AREA N Area of polygon – limited to polygon data SHAPE.LEN N Length of line – limited to line data 19/02/2016 12:32:42 PM Page 2 of 4 Feature class : GEOS_TECTONIC_UNITS_POLYGON_500K_GSD Feature category: Spatial type: Legend name: Description: Source: DMP custodian: ANZLIC metadata ID: Conditions of access: Item name Geology Region 1:500K Tectonic units of Western Australia 1:500 000 Tectonic units of Western Australia Department of Mines and Petroleum Geological Survey Division Subject to data custodian license agreement.
