无需使用Google API即可从地址获取经度和纬度

I am currently working on a large population-based database where it is required that I compute the distance between two addresses for each individual. My first train of thought was to obtain the latitude and longitude representing each address and then compute the distance. I used Google API's to obtain the latitude and longitude for these addresses via various packages in R (e.g. dismo). However Google has a restriction of 2500 requests in a 24hr period. I have about 300,000 addresses and by running 2,500/day, I will not be able to meet the deadline.

我目前正在开发一个基于人口的大型数据库，我需要计算每个人的两个地址之间的距离。我的第一个思路是获得代表每个地址的纬度和经度，然后计算距离。我使用Google API通过R中的各种包（例如dismo）获取这些地址的纬度和经度。但是，谷歌在24小时内限制了2500个请求。我有大约300,000个地址，每天运行2,500个，我将无法满足截止日期。

Would anyone have suggestions regarding other API's I could use to obtain the latitude and longitude using R?

有没有人会有关于其他API的建议我可以使用R来获取经度和纬度？

Thank you.

谢谢。

I would recommend that you try the RDSTK package which interfaces with the Data Science Toolkit. It is available on github.

我建议您尝试与Data Science Toolkit连接的RDSTK包。它可以在github上找到。

EDIT. To compute the Road Distance, I would recommend the Mapquest Directions API, which appears to have no preset limits as per this link. Let me know how it goes.

编辑。要计算道路距离，我建议使用Mapquest Directions API，根据此链接，该API似乎没有预设限制。让我知道事情的后续。

What you are doing is called "geocoding". Knowing that will greatly improve your ability to search for more info :) You may have already known that since you tagged the question properly, but I wanted to make sure.

你在做什么被称为“地理编码”。知道这将大大提高你搜索更多信息的能力:)你可能已经知道，因为你正确地标记了问题，但我想确保。

Here's a really good previous Stack Overflow question, albeit not R specific.

这是一个非常好的之前的Stack Overflow问题，尽管不是R特定的。

More options:

更多的选择：

The geonames package to retrieve information from the geonames service.
geonames包用于从地理名称服务中检索信息。
The osmar package to use the API of openstreetmap.
osmar包使用openstreetmap的API。

Besides, the gdistance package is useful for distance calculations on geographical grids.

此外，gdistance包对地理网格的距离计算很有用。
