监控摄像头位置数据库
为了更多地了解 django 编程,我计划创建一个谷歌地图混搭,它可以找到从 A 到 B 的路线,但避免穿过公共监控摄像头视角的街道/路口。 因此,我将创建一个数据库(可能基于 Postgres,因为它的 GIS 功能),其中包含
- 监视类型(监控摄像头、测速摄像头、道路收费摄像头等)
- 地理位置
- 超时(主要用于测速摄像头)
然后,该数据将当然,用户可以自由编辑。 然而,首先,我需要一些数据才能运行。 是否有任何此类公开数据库包含监控摄像头的(可能是近似的)地理位置?
To get more into django programming I'm planning to create a google maps mashup, which finds routes from A to B, but avoids streets/junctions that cross public surveillance cameras' perspectives. Therfore I will create a database (probably Postgres based, because of its GIS capabilities) containing
- surveillance type (surveillance camera, speed camera, road charge camera, etc.)
- geo position
- timeout (used mainly for speed cameras)
This data will then, of course, be editable freely by the users. To start, however, I will need some data to get running. Is there any such publicly available data base containing (possibly approximate) geo position of surveillance cameras?

openstreetmap 中是由 openstreetmap 社区用户绘制的监控摄像头。 该地图并不详尽,但将涵盖其他数据库中没有的摄像机。 我不知道 API 是否能很好地获取该摄像机的位置等。
In openstreetmap are surveillance cameras mapped by the users of the openstreetmap community. This maps are not exhaustive but will cover cameras that are not in other databases. I don't know how good the API is to get the position etc. of this cameras.
英国有一个测速摄像头数据库:
http://www.speedcamerasuk.com/locationsdatabase.htm
每个委员会都提供闭路电视摄像机的位置,Google 搜索应该会找到它们:
http://www.google.co.uk/search?hl=en&q=cctv+camera+location&btnG=Search&meta= cr%3DcountryUK|countryGB
尽管它们通常按街道名称列出,而不是正确的地理位置
The UK has a speed camera database:
http://www.speedcamerasuk.com/locationsdatabase.htm
and each council provides locations of CCTV cameras, a Google search should bring them up:
http://www.google.co.uk/search?hl=en&q=cctv+camera+location&btnG=Search&meta=cr%3DcountryUK|countryGB
though they are usually listed by their street name and not a proper geolocation
您可以使用 OpenStreetMap 来绘制闭路电视监控摄像头的地图:
http://wiki.openstreetmap.org/wiki/Tag:man_made%3Dsurveillance
添加它们后,闭路电视摄像机将在此地图上可见:

You can OpenStreetMap for mapping CCTV surveillance cameras:

And after you add them CCTV cameras will be visable on this map:

您对地点有什么偏好吗? http://www.mediaeater.com/cameras/ 有纽约市的摄像机列表; 尽管他们列出了文本位置而不是纬度/经度坐标,但他们确实发布了 PDF 地图,因此如果您提出要求,这些数据可能会可用。
Do you have any preferences as to location? http://www.mediaeater.com/cameras/ has camera lists for NYC; although they list text locations and not lat/long coordinates, they do publish PDF maps, so those data may be available if you ask nicely.
