Column Name Short Name Data Type Data Precision Comments
ORTHOPHOTO_TILE_POLY_ID OP_POLY_ID NUMBER 10 ORTHOPHOTO_TILE_POLY_ID is a system generated unique identification number.
GEOEXTENT_MAPSHEET GXTNT_MPST VARCHAR2 20 GEOEXTENT_MAPSHEET identifies the BCGS map sheet or other map sheet grid system tile name which contains the centroid point, e.g., 092b034.
FILENAME FILENAME VARCHAR2 100 FILENAME is the standard filename for the image, e.g., bc_092h007_xc500mm_utm10_2015.tif.
OWNER OWNER VARCHAR2 50 OWNER identifies the intellectual property owner of the image, e.g., Province of BC.
YEAR_OPERATIONAL YR_PRTNL NUMBER 4 YEAR is the operational year assigned to the photography from which this image has been compiled.
PROJECTION PROJECTION VARCHAR2 20 PROJECTION describes the native projection of the geo-referenced image, e.g., utm10.
RESOLUTION RESOLUTION VARCHAR2 20 RESOLUTION describes the distance on the ground represented by a single pixel in the image, e.g., 0.5 metre.
COLOUR_CONTENT COLOUR VARCHAR2 100 COLOUR_CONTENT describes the colour content of the image and any specific enhancements that may have been applied, e.g., colour - beetle-kill enhanced.
MAP_SYSTEM_GRID GRID VARCHAR2 30 MAP_SYSTEM_GRID identifies the specific map system grid into which the image is tiled, e.g., BCGS 1:5000.
RESTRICTED_IND RESTRICTED VARCHAR2 1 RESTRICTED_IND indicates if this image's geometry and metadata should not be exposed for viewing, i.e., Y, N.
ENHANCED_IND ENHANCED VARCHAR2 1 ENHANCED_IND indicates if any non-standard image processing has been applied to this image, i.e., Y, N.
THUMBNAIL_IMAGE_URL THMBNL_MGL VARCHAR2 500 THUMBNAIL_IMAGE_URL is a hyperlink to the 1/16th resolution thumbnail version of this image.
