Geocoding - Grouping multiple addresses into major cities

由 ╄→гoц情女王★ 提交于 2019-12-08 01:43:01
问题 Been hunting through previous questions on Geocoding and while many are helpful I'm not finding one to my needs. I need to group multiple addresses to the nearest city centers. My only address information is city, country, and state (if applicable). For example, all addresses in San Francisco and within miles should be listed as San Francisco. I'll need to know the count of addresses rolled-up to San Francisco. I'm open to suggestions on how to approach this. I don't particularly want to

IP localization: mapping ip->location fixed over time?

由 倖福魔咒の 提交于 2019-12-07 16:36:23
问题 I'm administering a web platform and want to get some statistical data, where my users come from.

Are there fixed tables, which IP address was given to which region? Must I request the mapping in the moment of the access or can I request it days/months/years later? In other words: Is the mapping from IP to location fixed or does it change over time? 回答1: The
