Object Description

Object Name: WHSE_WATER_MANAGEMENT.GW_NAQUADAT_STATION_SP

Short Name: GW_NAQS_SP
Comments: NAQUADAT ( National Water Quality Data Bank) STATION is Inventory of ambient water quality across Canada. Part of ENVIRODAT database. Includes flow, water depth and approximately 150 water quality parameters including nutrients, metals, pesticides and other organic contaminants. The spatial definition of NAQUADAT STATION consists of points representing the ground water quality stations for chemistry data. The dataset contains records from 700 stations located in the lower mainland covering the period 1954 to 1980. This is not a multipart feature.

Column Name Short Name Data Type Data Precision Comments
NAQ_STATION_CODE NAQ_STN_CD VARCHAR2 10 NAQ STATION CODE is the National Water Quality Data Bank Station number.
FEATURE_CODE FEAT_CODE VARCHAR2 10 A standard alphanumeric code to identify the type of feature represented by the spatial data. A feature code is most importantly a means of linking a feature to its name and definition. For example, the code GB15300120 on a digital geographic feature links it to the name "Lake - Dry" with the definition "A lake bed from which all water has drained or evaporated." The feature code does NOT mark when it was digitized, what dataset it belongs to, how accurate it is, what it should look like when plotted, or who is responsible for updating it. It only says what it represents in the real world. It also doesn't even matter how the lake is represented. If it is a very small lake, it may be stored as a point feature. If it is large enough to have a shape at the scale of data capture, it may be stored as an outline, or a closed polygon. The same feature code still links it to the same definition.
COMMENTS COMMENTS VARCHAR2 130 COMMENTS are the National Water Quality Data Bank Station notes.
GEOMETRY GEOMETRY SDO_GEOMETRY 1 GEOMETRY is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a required attribute of feature classes and object classes in a geodatabase.
SE_ANNO_CAD_DATA BLOB 4000 SE_ANNO_CAD_DATA is a binary column used by spatial tools to store annotation, curve features and CAD data when using the SDO_GEOMETRY storage data type.
