Ordnance Survey的CodePoint-Open数据的Python接口
项目描述
Ordnance Survey的CodePoint-Open的接口。CodePoint-Open是一个免费的地图数据集，将英国邮政编码映射到坐标。
oscodepoint读取此数据，无论是在原始zip文件中还是在解压缩后，解析数据，并将网格参考转换为纬度和经度。
数据集可以从http://www.ordnancesurvey.co.uk/oswebsite/products/code-point-open/下载
示例
>>> from oscodepoint import open_codepoint
>>> codepoint = open_codepoint('codepo_gb.zip')
>>> for entry in codepoint.entries():
... print entry['Postcode'], entry['Latitude'], entry['Longitude']
... break # Over 1.6 million rows
AB101AA 57.1482995075 -2.09663094048
数据量太大？尝试限制邮政编码区域
>>> from oscodepoint import open_codepoint
>>> codepoint = open_codepoint('codepo_gb.zip')
>>> for entry in codepoint.entries(areas=['NR', 'IP']):
... print entry['Postcode'], entry['Eastings'], entry['Northings']
... break
NR1 1AA 624068 308352
需要邮政编码所在的县？
邮政编码条目有一个Admin_country_code字段。 Doc/Codelist.xls将这些代码映射到县名，而codepoint.codelist可以用来访问此文件。例如
>>> from oscodepoint import open_codepoint
>>> codepoint = open_codepoint('codepo_gb.zip')
>>> county_list = codepoint.codelist['County']
>>> for entry in codepoint.entries(areas=['NR']):
... print entry['Postcode'], entry['Latitude'], entry['Longitude'], county_list.get(entry['Admin_county_code'])
... break
NR1 1AA 52.6266175146 1.30932087485 Norfolk County
获取邮政编码总数以供进度条使用
>>> from oscodepoint import open_codepoint
>>> codepoint = open_codepoint('codepo_gb.zip')
>>> print codepoint.metadata['area_counts']['NR']
22730
>>> print codepoint.metadata['total_count']
1692241
