资源简介：

The CT Municipalities layer consists of individual polygons representing each of the 169 municipalities that make up the state of Connecticut. This feature class is based on the Towns layer originally created by CTDEEP from USGS maps. The towns from the CTDEEP data were dissolved to create 169 records (one for each town). Fields were added and deleted to create a generic schema.The CT Municipalities feature class was created in (municipality) alphabetical order. Fields were added to identify the municipality number and the CTDOT Municipality number, which differ from each other in some cases. In 1947 the town of Saybrook officially changed its name to Deep River. Other State agencies and municipalities changed their numbering systems to reflect this name change, however, most of what is now CTDOT kept their existing numbering system. This is why the CTDOT town number for Deep River is 122, the number formerly assigned to Saybrook.The square miles associated with each town are for their interior land mass area. Coastal communities have boundaries that extend into Long Island Sound. These town boundary extensions into Long Island Sound are not included in the square miles field.CTDOT has created and will maintain a cartographic rendering of the geometric shape of Municipal boundaries. Official Town and City designations as incorporated areas consisting of an authorized governing body are managed by CT's Office of Policy and Management (OPM). CTDOT has undertaken a good faith effort to represent the boundaries cartographically in a fair and equitable fashion, from the best available data compiled from existing state, regional, and local resources including - existing historical cartographic renderings of the boundary locations, supplemental survey information, and map submissions. Corrections can be submitted to the CTDOT for incorporation and correction where applicable.Attribution was assigned to designations managed by a variety of entities that strictly follow Municipal boundaries and additional designations will be added as requested by State, regional, and local partners.

康涅狄格州市政图层（CT Municipalities）由代表康涅狄格州全部169个市政区域的独立多边形要素组成。该要素类基于康涅狄格州能源与环境保护部（CTDEEP）最初依托美国地质调查局（USGS）地图制作的城镇图层生成。CTDEEP数据中的城镇要素经融合处理后得到169条记录（每个城镇对应一条），并通过增删字段构建了通用数据架构。康涅狄格州市政要素类按市政名称的字母顺序排序。新增字段用于标识市政编号与康涅狄格州交通局（CTDOT）市政编号，二者在部分场景下存在差异。1947年，塞布鲁克镇正式更名为深河镇（Deep River）。其他州级机构与市政部门均更新了编号系统以适配此次更名，但绝大多数CTDOT仍沿用原有编号体系。这便是深河镇的CTDOT城镇编号为122（原塞布鲁克镇的编号）的原因。各城镇对应的平方英里数为其内陆陆域面积。沿海社区的行政边界延伸至长岛湾（Long Island Sound），但此类延伸至长岛湾的城镇边界范围未计入平方英里字段。 CTDOT已制作并将持续维护市政边界几何形状的制图渲染成果。由经授权治理机构组成的法定建制城镇与城市的官方命名，由康涅狄格州政策与管理办公室（Office of Policy and Management, OPM）负责管理。 CTDOT秉持诚意，依托现有州级、区域及本地资源中的最优可用数据（包括边界位置的历史制图成果、补充勘测信息与提交的地图），以公平公正的方式对边界进行制图呈现。若有更正需求，可提交至CTDOT，以便在适用情况下进行整合与修正。属性信息已分配给严格遵循市政边界的各类实体所管理的命名标识，后续将根据州级、区域及本地合作伙伴的需求新增更多命名标识。
