寻求美国城市边界的shapefile?

您没有说是否使用esri。
ESRI产品随附“数据和地图” dvd。
它不在shp中,但可以使用arcmap选择并转换为形状。
我在mapdata文件夹中的网络驱动器上安装了我的。其余的路径是这样的。
G:\ MapData \ ESRI_Data \ streetmap_na \ data \ citylim.sdc

检查TIGER / Line文件。您想为每个州寻找“放置”层,您可以通过选择每个州在基于国家的shapefile下进行细化。或者,对于2012版本,您可以从此页面获取所有状态。

您可以在此处获取美国人口普查位置数据,其中包括城市。

例如,可在此处获取罗德岛州的2017年地点数据。

解释数据

在此处获得2017年美国人口普查数据的技术文档。我是通过在Google上搜索“ namelsad classfp”(先前获取的shapefile中的异常字段名称)找到的。

在文件中搜索“ _place”(带下划线),以查找先前获取的shapefile中字段的含义。这些是:

Field    Length   Type     Description
STATEFP       2   String   Current state FIPS code
PLACEFP       5   String   Current place FIPS code
PLACENS       8   String   Current place GNIS code
GEOID         7   String   Place identifier; a concatenation of the current state FIPS code and place FIPS code
NAME        100   String   Current place name
NAMELSAD    100   String   Current name and the translated legal/statistical area description for place
LSAD          2   String   Current legal/statistical area description code for place
CLASSFP       2   String   Current FIPS class code
PCICBSA       1   String   Current metropolitan or micropolitan statistical area principal city indicator
PCINECTA      1   String   Current New England city and town area principal city indicator
MTFCC         5   String   G4110 (incorporated place) and G4210 (census designated place)
FUNCSTAT      1   String   Current functional status
ALAND        14   Number   Current land area
AWATER       14   Number   Current water area
INTPTLAT     11   String   Current latitude of the internal point
INTPTLON     12   String   Current longitude of the internal poin

然后,您将想知道该CLASSFP列的值。这些在这里可用。一些相关的是:

C1 An incorporated place that is governmentally active, is not related to an
Alaska Native village statistical area (ANVSA), and does not serve as a
minor civil division (MCD) equivalent.

C2 Incorporated place that also serves as a minor civil division (MCD)
equivalent because, although the place is coextensive with an MCD, the U.S.
Census Bureau, in agreement with state officials, does not recognize that
MCD for presenting census data because the MCD cannot provide governmental
services (applies to Iowa and Ohio only).

C3 Incorporated place that is a consolidated city.

C5 Incorporated place that also serves as a minor civil division (MCD)
equivalent because it is not part of any MCD or a county subdivision
classified as Z5.

C6 Incorporated place that coincides with or approximates an Alaska Native
village statistical area (ANVSA).

C7 An incorporated place that is an independent city; that is, it also
serves as a county equivalent because it is not part of any county and a
minor civil division (MCD) equivalent because it is not part of any MCD.

C8 The portion ("balance") of a consolidated city that excludes the
separately incorporated place(s) within that jurisdiction.

C9 An incorporated place whose government is operationally inactive and is
not included in any other C subclass.

U1 Census designated place (CDP) with a name that is commonly recognized for
the populated area, and designated as a populated place by the U.S.
Geological Survey.

U2 Census designated place (CDP) with a name that is not commonly recognized
for the populated area (e.g., a combination of the names of two or three
commonly recognized communities, or a name that identifies the location of
the CDP in relation to an adjacent incorporated place).

U9 A census designated place (CDP) that coincides with, or approximates, an
Alaska Native Village Statistical Area (ANVSA).

我想您可以通过规模和/或人口来推断主要城市。在这种情况下,你可以使用这个预连接地理数据库,其拥有2010城市边界与区域和基本的人口估算值。

koordinates.com是一个免费的地方,可以找到各种城市边界shapefile。您甚至可以选择坐标系。这是到德克萨斯州城市的链接

做一些寻找其他城市。他们在这个网站上有很多。您确实需要创建一个登录名。
