Mencari shapefile batas kota di AS?

Di mana saya dapat menemukan shapefile yang berisi batasan untuk kota-kota besar di Amerika Serikat?

Saya telah mencoba situs sensus tetapi tidak dapat menemukan apa pun.

Data TIGER dari biro sensus tersedia di http://www.census.gov/geo/www/tiger/

Agak tua tapi vaild.

Anda tidak mengatakan apakah Anda menggunakan esri atau tidak.
Produk ESRI dilengkapi dengan dvd "data dan peta".
Ini bukan di shp tetapi dapat dipilih dan dikonversi ke bentuk menggunakan arcmap.
Saya memasang tambang di drive jaringan di folder map data. Sisa dari jalan adalah seperti ini.
G: \ MapData \ ESRI_Data \ streetmap_na \ data \ citylim.sdc

Periksa file TIGER / Line. Anda ingin mencari "Tempatkan" lapisan untuk setiap negara bagian, yang dapat Anda pilih di bawah shapefile berbasis nasional dengan memilih setiap negara bagian. Atau, untuk versi 2012, Anda dapat mengambil semua status dari halaman ini .

Menafsirkan Data

Dokumentasi teknis untuk Data Sensus AS 2017 tersedia di sini . Saya menemukannya dengan mencari "namelsad classfp" di Google (nama bidang yang tidak biasa dari shapefile yang diperoleh sebelumnya).

Cari file untuk "_place" (dengan garis bawah) untuk menemukan arti bidang di shapefile yang diperoleh sebelumnya. Ini adalah:

Anda kemudian ingin tahu nilai-nilai CLASSFPkolom. Ini tersedia di sini . Beberapa yang relevan adalah:

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).

File ini besar tapi saya rasa itu bisa dipangkas sesuai kebutuhan Anda.

Saya kira Anda dapat menyimpulkan kota-kota besar berdasarkan ukuran dan / atau populasi. Dalam kasus tersebut, Anda dapat menggunakan ini pre-bergabung geodatabase yang memiliki 2010 batas kota bersama dengan daerah DAN perkiraan populasi dasar.

koordinates.com adalah tempat gratis untuk menemukan berbagai bentuk batas kota. Anda bahkan dapat memilih sistem koordinat. Berikut ini tautan ke kota-kota Texas.

Lakukan pencarian di sekitar kota-kota lain. Mereka punya banyak di situs web ini. Anda harus membuat login.
