Object Description

Object Name: WHSE_LAND_USE_PLANNING.RKPM_KARST_POTENTIAL_AREA_SP

Short Name: RKPM_KPA
Comments: KARST POTENTIAL AREA SP spatial definition consists of polygons representing reconnaissance level (1:250,000) mapping of potential karsts within British Columbia. The polygons intended to highlight where karst areas may occur and to estimate the likely intensity of karst development in these areas. This type of map differs from a simple karst map, which would display features and characteristics of only the known karst locations. This is not a multipart feature.

Column Name Short Name Data Type Data Precision Comments
KARST_POTENTIAL_AREA_ID KA_POT_AID NUMBER 10 KARST POTENTIAL AREA ID is a primary unique numeric identifier for a feature.
FEATURE_CODE FEAT_CODE VARCHAR2 10 FEATURE CODE is 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.
GEOLOGICAL_UNIT_NAME GEOL_U_NAM VARCHAR2 120 GEOLOGICAL UNIT NAME is the Name of geological unit from BC Geological Survey (BCGS) Open File 1994 to 1997.
SOLUBLE_BEDROCK_PROPORTION SO_BR_PROP VARCHAR2 15 SOLUBLE BEDROCK PROPORTION is the estimated proportion of soluble bedrock in unit.
SOLUBLE_BEDROCK_CONFIDENCE SO_BR_CONF VARCHAR2 120 SOLUBLE BEDROCK CONFIDENCE is the confidence in estimate of SOLUBLE BEDROCK PROPORTION coding self explanatory.
KARST_LIKELIHOOD KARST_LIKE VARCHAR2 1 KARST LIKELIHOOD is the Likelihood of karst forming bedrock based on the proportion of soluble bedrock; P = primary = >50% soluble bedrock; S = secondary = 20% to 49% soluble bedrock; T = tertiary = 5% to 19% soluble bedrock .
CHEMICAL_PURITY CHEM_PURTY VARCHAR2 48 CHEMICAL PURITY is the description of the bulk (or chemical) purity of any soluble bedrock.
CHEMICAL_PURITY_RATING CHEM_P_RAT VARCHAR2 1 CHEMICAL PURITY RATING is the rating applied to CHEMICAL PURITY: 1 (very impure) to 5 (purest).
LITHOLOGY_DESCRIPTION LITH_DESCR VARCHAR2 120 LITHOLOGY DESCRIPTION is the description of unit enabling interpretation of lithological form or distribution of the soluble bedrock component within a specific geological unit.
LITHOLOGY_RATING LITH_RATNG VARCHAR2 1 LITHOLOGY RATING is the rating of lithological form 1 (lowest) Small (metre scale) discontinuous layers and pods were given the lowest rating 2 or 3 soluble bedrock type was comprised of multiple interbeds 4 bedrock types that occur as a single bed or a few beds within a unit, but also include other insoluble bedrock interbeds 5 soluble bedrock types that occur as a single or a few beds within a unit.
THICKNESS_CONTINUITY THICK_CONT VARCHAR2 120 THICKNESS CONTINUITY is the description of the thickness and continuity of the unit.
THICKNESS_CONTINUITY_RATING THIK_C_RAT VARCHAR2 1 THICKNESS CONTINUITY RATING is the rating of THICK and CONTINUITY: 1 (lowest) to 5 (highest).
KARST_DEVELOPMENT_CONFIDENCE KA_DEV_CON VARCHAR2 120 KARST DEVELOPMENT CONFIDENCE is the Reliability of CRITERION#2 (with description or reference) 1 (lowest) to 5 (highest).
TOPOGRAPHIC_POSITION TOPO_POSTN VARCHAR2 50 TOPOGRAPHIC POSITION is the description of topographic positions.
TOPOGRAPHIC_POSITION_RATING TOPO_P_RAT VARCHAR2 1 TOPOGRAPHIC POSITION RATING is the rating of TOPOGRAPHIC POSITION 1 (lowest) to 5 (highest).
KARST_DEVELOPMENT_INTENSITY KA_DEV_INT VARCHAR2 1 KARST DEVELOPMENT INTENSITY is the estimated intensity of karst development = (4*CHEMPURITYRATING)+(3*LITHOLOGYRATING)+(THICK and CONTRATING)+(2*TOPOPOSITIONR); H = high = 38 to 50; M = moderate = 27 to 37; L = low = 16 to 26.
KNOWN_CAVES_IND KN_CAV_IND VARCHAR2 3 KNOWN CAVES determines if caves are known to occur in unit. Values "Yes" or "No".
CAVE_INFORMATION CAVE_INFO VARCHAR2 91 CAVE INFORMATION is the name or other information about caves if available.
KNOWN_KARST_IND KN_KAR_IND VARCHAR2 3 KNOWN KARST is whether karst actually known to occur in unit - YES; NO.
KARST_INFORMATION KARST_INFO VARCHAR2 120 KARST INFORMATION is the name or other information about karst if available.
INFORMATION_SOURCE INFO_SOURC VARCHAR2 120 INFORMATION SOURCE is the source of information about caves and karst.
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.
FEATURE_AREA_SQM FEAT_AREA NUMBER 19 FEATURE_AREA_SQM is the system calculated area of a two-dimensional polygon in square meters
FEATURE_LENGTH_M FEAT_LEN NUMBER 19 FEATURE_LENGTH_M is the system calculated length or perimeter of a geometry in meters
