ABD'de şehir sınırlarının şekil dosyasını mı arıyorsunuz?

Amerika Birleşik Devletleri'ndeki büyük şehirler için sınırlar içeren bir şekil dosyasını nerede bulabilirim?

Sayım web sitesini denedim ama hiçbir şey bulamadım.

Sayım bürosundaki TIGER verilerine http://www.census.gov/geo/www/tiger/ adresinden ulaşılabilir.

Biraz yaşlı ama boş.

Esri kullanıp kullanmadığınızı söylemiyorsunuz.
ESRI Ürünleri "veri ve haritalar" dvd'si ile gelir.
Shp biçiminde değildir ancak arcmap kullanılarak seçilebilir ve şekle dönüştürülebilir.
Benimkini mapdata klasöründeki bir ağ sürücüsüne yükledim. Yolun geri kalanı böyle.

TIGER / Line dosyalarını kontrol edin. Her eyalet için ulusal tabanlı şekil dosyalarının altında ince ayar yapabileceğiniz her durum için "Yerleştir" katmanları aramak istiyorsunuz . Veya 2012 sürümü için bu sayfadan tüm durumları alabilirsiniz .

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.

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).
