Additional Information

Purpose

This Spatial layer indicates the date that each pixel in the Landsat 5 used in Baseline Thematic Mapping Land Use Polygons (BTM) v1 was captured from the satellite. The same images were included an an Image Catalogue in ArcInfo and .JPG format. This layer will assist with using the BTM v1 or hte Image Catalogue for change detection, and also indicate the currency of the images.

Object Description

Object Name: WHSE_BASEMAPPING.SII_LANDSAT_ACQUS_DATE_AREA_SP

Short Name: SII_ACQDAT
Comments: BTM ( Baseline Thematic Mapping) Landsat Image Catalogue Acquisition Dates. This polygon coverage contains the date of capture of the Landsat images making up the seamless BC Landsat image catalogue. This is not a multipart feature.

Column Name Short Name Data Type Data Precision Comments
LANDSAT_ACQUS_DATE_AREA_ID LAD_AR_ID NUMBER 10 Primary unique numeric identifier for a Polygon.
NTS_MAPSHEET_ID NTS_MAP_ID VARCHAR2 32 National Topographic Series 1:250 000 Map number
FEATURE_CODE FEAT_CODE VARCHAR2 10 A standard numeric 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.
IMAGE_ACQUISITION_YEAR IMAG_A_YR NUMBER 4 Numeric Year of image acquisition by Landsat satellite.
IMAGE_ACQUISITION_MONTH IMAG_A_MON NUMBER 2 Numeric Month of image acquisition by Landsat satellite.
IMAGE_ACQUISITION_DAY IMAG_A_DAY NUMBER 2 Day of image acquisition by Landsat satellite.
GEOMETRY GEOMETRY SDO_GEOMETRY 1
OBJECTID OBJECTID NUMBER 38
SE_ANNO_CAD_DATA BLOB 4000
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
