QLD_BASINSUBAREA_100K - Queensland is polygon coverage captured and stored in ArcInfo, depicting a subdivision of the major drainage basins in Queensland. Its original purpose was to implant some location identifier into the numbering system of bores and gauging stations. For example all bore numbers were prefixed with a four-digit number. The first three were used to locate the bore into a specific major river basin .The forth digit was used to located the bore into a subdivision of that major river basin as shown in the Sub-Basin Areas - Queensland coverage. This coverage is now only used as a means of numbering bores and gauging stations. Its capture scale is 1:100 000. |
