需要幫助查找特定郵政編碼的KML數據

Question

我正在使用新澤西郵政編碼製作熱圖，但我使用的幾何信息對於兩個郵政編碼不正確。有誰知道我可以去哪裏獲取這兩個特定郵政編碼的KML信息？我在這裏看到了很多關於KML數據使用哪些資源的帖子，但他們都非常先進，我不知道如何挖掘論壇上其他人鏈接到的數據庫。

具體而言，我需要ZIP碼的KML郵政編碼數據08559和08757.以下是這些ZIP代碼的有缺陷的KML數據我有：

08559：

<Polygon><outerBoundaryIs><LinearRing><coordinates>-74.892528,40.414294,0.0 -74.967386,40.39857,0.0 -75.060361,40.420788,0.0 -75.064463,40.500774,0.0 -75.06583,40.517523,0.0 -75.068223,40.457705,0.0 -74.991314,40.481632,0.0 -74.88911,40.47001,0.0 -74.892528,40.414294,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon> 

08757：

<Polygon><outerBoundaryIs><LinearRing><coordinates>-74.190432,39.946002,0.0 -74.221537,39.932329,0.0 -74.322374,39.946002,0.0 -74.234185,40.008896,0.0 -74.26905,39.986678,0.0 -74.206839,39.952154,0.0 -74.19761,39.949762,0.0 -74.190432,39.946002,0.0</coordinates></LinearRing></outerBoundaryIs></Polygon> 

Answer 1

對於剛剛美國郵政編碼沒有可用的數據來自美國人口普查局： http://www.census.gov/geo/www/cob/z52000.html#ascii

下載新澤西州或任何其他50個州的ASCII數據集。

您可以查找索引您的郵政編碼，在小文件（例如zt34_d00a.dat）

317 
"08559" 
"08559" 
"Z5" 
"5-Digit ZCTA" 

然後找到匹配的經度/緯度在大文件座標列表。

317  -0.749719256389896E+02  0.404391641604938E+02 
     -0.750611840000000E+02  0.404766960000000E+02 
     -0.750607720000000E+02  0.404766880000000E+02 
     -0.750620530000000E+02  0.404692640000000E+02 
     -0.750637010000000E+02  0.404652440000000E+02 
... 
     -0.750622670000000E+02  0.404709200000000E+02 
     -0.750611840000000E+02  0.404766960000000E+02 
END 

第一個值是經度，第二個值是以十進制度表示的緯度。

請注意，某些點可能無序（或錯誤），因此您在轉換爲KML後可能必須將其清除。幫助調試點並刪除不良點的便利工具是KML Number-the-points tool，它生成KML Placemarks，每個KML Placemarks的數字標籤對應於一行或多邊形中的每個點，並給定一些KML作爲輸入。有用的，如果有很長的點，並需要輕鬆識別它們。

Answer 2

如何與多個郵政編碼

含 census.gov所有美國郵政編碼

1. 下載KML文件創建一個區域圖。本網站最新的文件是：http://www2.census.gov/geo/tiger/GENZ2015/kml/cb_2015_us_zcta510_500k.zip。如果此鏈接損壞，請在Google搜索site:census.gov KML ZIP。另一種選擇：https://www.filosophy.org/post/17/zipcodes_in_kml/

打開這個巨大的（175MB）的文本文件中明文編輯和搜索你想要的郵政編碼和複製<Polygon>節。下面是結果爲>94117搜索時：

造清潔KML文件並移動<Polygon>到該文件。以下是帶有兩個郵政編碼多邊形的KML文件（service-delivery-area.kml）的示例。谷歌有一個偉大的KML Reference。

轉到https://www.google.com/mymaps/並創建新的地圖。點擊「添加新圖層」，然後點擊「導入」，然後上傳您的KML文件。如果多邊形不正確，則可以編輯地圖上的多邊形。

你的地圖應該有這樣的結果：https://www.google.com/maps/d/u/0/embed?mid=1zop5GMD1b2afmOvObQIi7YvF1d4
