资源简介:

This layer contains information for locating past and present legal city boundaries within Los Angeles County. The Los Angeles County Department of Public Works provides the most current shapefiles representing city annexations and city boundaries on the Los Angeles County GIS Data Portal. True, legal boundaries are only determined on the ground by surveyors licensed in the State of California. Numerous records are freely available at the Land Records Information website, hosted by the Department of Public Works. Principal Attributes: NO: The row number in the attribute table of the PDF Annexation Maps. (See Below) ANNEX_No: These values are only used for the City of Los Angeles and Long Beach. NAME: The official annexation name. TYPE: Indicates the legal action. A - represents an Annexation to that city. D - represents a Detachment from that city. V - is used to indicate the annexation was void or withdrawn before an effective date could be declared. 33 - Some older city annexation maps indicate a city boundary declared 'as of February 8, 1933'. ANNEX_AREA: is the land area annexed or detached, in square miles, per the recorded legal description. TOTAL_AREA: is the cumulative total land area for each city, arranged chronologically. SHADE: is used by some of our cartographers to store the color used on printed maps. INDEXNO: is a matching field used for retrieving documents from our department's document management system. STATE (Secretary of State): Date filed with the Secretary of State. These are not available for earlier annexations and are Null. COUNTY (County Recorder): Date filed with the County Recorder. These are not available for earlier annexations and are Null. EFFECTIVE (Effective Date): The effective date of the annexation or detachment. CITY: The city to which the annexation or detachment took place. URL: This text field contains hyperlinks for viewing city annexation documents. See the ArcGIS Help for using the Hyperlink Tool. FEAT_TYPE: contains the type of feature each polygon represents: Land - Use this value for your definition query if you want to see only land features on your map. Pier - This value is used for polygons representing piers along the coastline. One example is the Santa Monica Pier. Breakwater - This value is used for polygons representing man-made barriers that protect the harbors. Water - This value is used for polygons representing navigable waters inside the harbors and marinas. 3NM Buffer - Per the Submerged Lands Act, the seaward boundaries of coastal cities and unincorporated county areas are three nautical miles from the coastline. (A nautical mile is 1,852 meters, or about 6,076 feet.) Annexation Maps by City (PDF) Large format, high quality wall maps are available for each of the 88 cities in Los Angeles County in PDF format.

本图层包含用于定位洛杉矶县境内过往及现行法定城市边界的相关信息。洛杉矶县公共工程部(Los Angeles County Department of Public Works)在洛杉矶县地理信息系统(GIS)数据门户中提供了最新的城市兼并与城市边界形状文件(shapefile)。需明确,法定边界仅可由加州持证测量员在实地进行判定。公共工程部托管的土地记录信息网站(Land Records Information website)可免费获取大量相关记录。 核心属性说明如下: 1. NO:PDF版兼并地图属性表中的行号(详见下文)。 2. ANNEX_No:该字段仅适用于洛杉矶市与长滩市(Long Beach)。 3. NAME:官方兼并名称。 4. TYPE:用于标识法定操作类型,具体含义如下: - A:代表向对应城市的土地兼并操作; - D:代表从对应城市的土地脱离操作; - V:用于标注在生效日期确定前已作废或撤回的兼并操作; - 33:部分老旧城市兼并地图会标注该城市边界“以1933年2月8日为准”。 5. ANNEX_AREA:按备案法定描述计算的被兼并或脱离区域的土地面积,单位为平方英里。 6. TOTAL_AREA:按时间顺序排列的各城市累计总土地面积。 7. SHADE:部分制图人员用于存储印刷地图所用配色的字段。 8. INDEXNO:用于从本部门文档管理系统中检索文档的匹配字段。 9. STATE(州务卿办公室):向州务卿备案的日期。该字段对于早期兼并操作无相关记录,值为空值(Null)。 10. COUNTY(县书记员办公室):向县书记员备案的日期。该字段对于早期兼并操作无相关记录,值为空值(Null)。 11. EFFECTIVE(生效日期):兼并或脱离操作的正式生效日期。 12. CITY:发生兼并或脱离操作对应的城市名称。 13. URL:包含用于查看城市兼并文档的超链接文本字段,超链接工具的具体使用方法可参考ArcGIS帮助文档。 14. FEAT_TYPE:包含每个多边形所代表的要素类型,具体如下: - Land:若仅需在地图上显示陆地要素,可使用该值进行定义查询; - Pier:用于代表沿海岸线码头的多边形,例如圣塔莫尼卡码头(Santa Monica Pier); - Breakwater:用于代表保护港口的人工防护堤的多边形; - Water:用于代表港口与码头内通航水域的多边形; - 3NM Buffer:根据《水下土地法(Submerged Lands Act)》,沿海城市及未合并县辖区的向海边界距海岸线三海里(1海里等于1852米,约6076英尺)。 城市兼并地图(PDF版):洛杉矶县88个城市均可获取大幅面、高质量的PDF格式墙面地图,具体城市列表如下: 阿古拉山(Agoura Hills)、赫莫萨比奇(Hermosa Beach)、诺沃克(Norwalk)、阿罕布拉(Alhambra)、希登希尔斯(Hidden Hills)、棕榈谷(Palmdale)、阿卡迪亚(Arcadia)、亨廷顿帕克(Huntington Park)、帕洛斯弗迪斯庄园(Palos Verdes Estates)、阿特西亚(Artesia)、工业市(Industry)、派拉蒙(Paramount)、阿瓦隆(Avalon)、英格尔伍德(Inglewood)、帕萨迪纳(Pasadena)、阿祖萨(Azusa)、欧文代尔(Irwindale)、皮科里维拉(Pico Rivera)、鲍德温公园(Baldwin Park)、拉肯纳达弗林特里奇(La Canada Flintridge)、波莫纳(Pomona)、贝尔(Bell)、拉哈布拉高地(La Habra Heights)、兰乔帕洛斯弗迪斯(Rancho Palos Verdes)、贝尔加登斯(Bell Gardens)、拉米拉达(La Mirada)、雷东多比奇(Redondo Beach)、贝尔弗劳尔(Bellflower)、拉普恩特(La Puente)、罗灵希尔斯(Rolling Hills)、贝弗利山庄(Beverly Hills)、拉弗恩(La Verne)、罗灵希尔斯庄园(Rolling Hills Estates)、布拉德伯里(Bradbury)、莱克伍德(Lakewood)、罗斯米德(Rosemead)、伯班克(Burbank)、兰卡斯特(Lancaster)、圣迪马斯(San Dimas)、卡拉巴萨斯(Calabasas)、劳恩代尔(Lawndale)、圣费尔南多(San Fernando)、卡森(Carson)、洛米塔(Lomita)、圣盖博(San Gabriel)、塞里托斯(Cerritos)、长滩(Long Beach)、圣马力诺(San Marino)、克莱蒙特(Claremont)、洛杉矶(Los Angeles)、索引(Index)、圣克拉丽塔(Santa Clarita)、商业市(Commerce)、洛杉矶地图1(Los Angeles Map 1)、圣达菲斯普林斯(Santa Fe Springs)、康普顿(Compton)、洛杉矶地图2(Los Angeles Map 2)、南埃尔蒙特(South El Monte)、科维纳(Covina)、洛杉矶地图3(Los Angeles Map 3)、谢拉马德雷(Sierra Madre)、卡达希(Cudahy)、洛杉矶地图4(Los Angeles Map 4)、锡格尔希尔(Signal Hill)、卡尔弗城(Culver City)、洛杉矶地图5(Los Angeles Map 5)、南门(South Gate)、唐尼(Downey)、洛杉矶地图6(Los Angeles Map 6)、南帕萨迪纳(South Pasadena)、杜阿尔特(Duarte)、洛杉矶地图7(Los Angeles Map 7)、坦普尔城(Temple City)、埃尔蒙特(El Monte)、林伍德(Lynwood)、托伦斯(Torrance)、埃尔塞贡多(El Segundo)、马里布(Malibu)、弗农(Vernon)、加迪纳(Gardena)、曼哈顿海滩(Manhattan Beach)、核桃市(Walnut)、格伦代尔(Glendale)、梅伍德(Maywood)、西科维纳(West Covina)、格伦多拉(Glendora)、蒙罗维亚(Monrovia)、西好莱坞(West Hollywood)、夏威夷花园(Hawaiian Gardens)、蒙特贝洛(Montebello)、西湖村(Westlake Village)、霍桑(Hawthorne)、蒙特雷帕克(Monterey Park)、惠蒂尔(Whittier)
