Column Name Short Name Data Type Data Precision Comments
HISTORICAL_INDEX_MAP_ID HSTRCL__ID NUMBER 38 HISTORICAL_INDEX_MAP_ID identifies the record containing the unique combination of footprint and date range of an individual map in the provincial historical air photo index map collection.
SCALE_CATEGORY SCALE_CAT VARCHAR2 10 SCALE_CATEGORY describes the category of photo scale for the film rolls depicted in the map, i.e., small, medium, or large.
GEOEXTENT_MAPSHEET GEOEX_MPST VARCHAR2 10 GEOEXTENT_MAPSHEET is the descrioption of the map extents expressed as a standard NTS tile or prtion of a tile, e.g., 082g_w decribes a map extent that is the western half of NTS map tile 82G.
MAP_TAG MAP_TAG VARCHAR2 10 MAP_TAG is the short-form name of the hardcopy version of this map, e.g., 082f_e_4 describes the 4th large scale index map in the series for the eastern half of NTS map tile 82E.
START_YEAR START_YEAR NUMBER 38 START_YEAR is the first year of photo acquisition that appears on this map.
END_YEAR END_YEAR NUMBER 38 END_YEAR is the last year of photo acquisition that appears on this map .
KML_URL KML_URL VARCHAR2 500 KML_URL is a hyperlink to the Google Earth image overlay of the index map in .kml format.
PDF_URL PDF_URL VARCHAR2 500 PDF_URL is a hyperlink to the digital version of the index map in .pdf format.
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.
SHAPE SHAPE SDO_GEOMETRY 1 SHAPE is the column used to reference the spatial coordinates defining the feature.
OBJECTID OBJECTID NUMBER 38 OBJECTID is a column required by spatial layers that interact with ESRI ArcSDE. It is populated with unique values automatically by SDE.
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.
