The project describes itself as "an organized sampling of the world". ==Requirements== The precise location of each degree confluence uses the WGS 84 horizontal datum, and visitors to degree confluences almost always make use of GPS receivers. For a ''successful visit'', the visitor must get within 100 metres of the confluence point, and post a narrative and several photographs to the project website. A visit, or attempted visit, which does not conform to these rules may still be recorded on the website as an ''incomplete visit''. The project encourages visits to degree confluences which have been visited previously, and many confluence points in North America and Europe have been visited several times. The total number of degree confluences is 64,442,〔Latitude lines 89°N to 89°S (179), multiplied by 360° of longitude (360), plus the two poles (2) = 179 × 360 + 2 = 64,442.〕 of which 21,543 are on land, 38,409 on water, and 4,490 on the Antarctic and Arctic ice caps.〔(Classifications as of August 4, 2007 )〕 The project categorizes degree confluences as either ''primary'' or ''secondary''. A confluence is primary only if it is on land or within sight of land. In addition, at higher latitudes only some points are designated primary, because confluences crowd together near the poles.〔(Poles Problem )〕 Both primary and secondary confluences may be visited and recorded. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Degree Confluence Project」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
