General Electorates 2007

GED2007_V1_00 comprises general electoral district boundaries as defined by the Representation Commission as at 25 September 2007. General Electoral District 2007 is the definitive set of 2007 general electoral district boundaries as defined by the Representation Commission. Land Information New Zealand (LINZ) and Stats NZ are the custodians. These boundaries comprise the general electoral districts as constituted under the Electoral Act 1993. General electoral districts extend to the 12-mile limit and are defined at meshblock level. The number of general electoral districts, and electoral populations for each electorate, are calculated using formula in the Electoral Act 1993. The Representation Commission is convened by the Surveyor-General every five years following a Census of Population and Dwellings, and Māori Electoral Option. Its role is to re-draw electoral boundaries to make sure each electorate has about the same number of people. When setting the boundaries, the Representation Commission also considers existing boundaries, community of interest, the infrastructure that links communities (such as main roads), topographical features, and any projected variation in the population of those districts during their existence. General Electoral District is a flat classification with 63 categories. These boundaries were used for the 2008 and 2011 New Zealand general elections. This layer has been generalised, i.e. simplified for rapid drawing and is designed for thematic or web mapping purposes.GED2007_V1_00 数据集包含截至2007年9月25日由代表委员会（Representation Commission）划定的通用选举区边界。2007年通用选举区数据集（General Electoral District 2007）为代表委员会划定的2007年通用选举区边界的权威正式版本。新西兰土地信息局（Land Information New Zealand, LINZ）与新西兰统计局（Stats NZ）为该数据集的保管方。 上述边界为依据《1993年选举法》（Electoral Act 1993）设立的通用选举区范围。通用选举区的管辖范围延伸至12海里领海界限，且以网格块（meshblock）级别进行定义。通用选举区的数量及各选区的选举人口，均通过《1993年选举法》中规定的公式计算得出。 代表委员会由测量总长（Surveyor-General）在每五年一次的人口与住房普查（Census of Population and Dwellings）及毛利人选民选择权（Māori Electoral Option）之后召集组建，其职责为重新划定选举区边界，确保各选区的人口数量大致均等。在划定边界时，代表委员会还需考量现有边界、利益相关社区、连接社区的基础设施（如主要道路）、地形特征，以及各选区在任期内的预计人口变动情况。 通用选举区为包含63个类别的扁平分类体系。该边界数据集曾应用于2008年与2011年新西兰大选。此图层已进行概化处理——即简化几何形状以实现快速绘制，专为专题制图或网络地图绘制场景设计。
