Где я могу найти шейп-файл, который содержит границы для крупных городов в Соединенных Штатах?
Я перепробовал сайт переписи, но ничего не смог найти.

Ответы:
Данные TIGER из бюро переписей доступны по адресу http://www.census.gov/geo/www/tiger/.
Немного стар, но завораживал.

Вы не говорите, используете ли вы esri или нет.
Продукты ESRI поставляются с DVD-диском «данные и карты».
Его нет в shp, но его можно выбрать и преобразовать в фигуру с помощью arcmap.
Я установил мой на сетевой диск в папке mapdata. Остальная часть пути такова.

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.

Census Bureau, in agreement with state officials, does not recognize that
MCD for presenting census data because the MCD cannot provide governmental

equivalent because it is not part of any MCD or a county subdivision
classified as Z5.

serves as a county equivalent because it is not part of any county and a
