Rates Limits in Geocoding [Open Street Map]

[delgado]

Hello,

I'm working on a project where I have to do a georeferencing about 100k addresses. I used an open source (Open Street Map) to georeference them. However, after some research I realized that there is a limit of Requests. And in order to georeference around 1000 addresses, the program explodes ... In this situation, I used a Sys.sleep (0.5) function which is to do half a second interval between each address search. AND the program continues exploding...

Can someone help me find a function or line of code that allows the program to only make one address per second?

I hope someone can help me in this problem.
Thank you,
Pedro.

Looks like someone else had the same question re. the rate limit

Leaflet and OpenStreetMap rate limits?

Thanks for the hint. To answer my original question I found that OpenStreetMap provides an API that can be accessed using jsonlite package in R and with which it is possible to geocode addresses. The rate limit is 1 request per second.

I haven't used it personally, but there's a package, ratelimitr, that will let you set a rate limit on any R function:

GitHub - tarakc02/ratelimitr: Rate limiting for R functions

From the README:

library(ratelimitr)
f <- function() NULL

# create a version of f that can only be called 10 times per second
f_lim <- limit_rate(f, rate(n = 10, period = 1))

# time without limiting
system.time(replicate(11, f()))
#>    user  system elapsed 
#>       0       0       0

# time with limiting
system.time(replicate(11, f_lim()))
#>    user  system elapsed 
#>    0.00    0.00    1.05
