[twitter-dev] Twitter Stream API - Location filtering limited to the Western Hemisphere?
I'm attempting to stream Tweets from the UK as a whole(filtering further with tracking words), using Twitters stream API, however I'm having trouble with my bounding box. The LAT/LON pairs I'm using to define a bounding box of the whoe UK(Ire included) is as follows. -9.05, 48.77, 2.19, 58.88 However when I try to use this with the Twitter stream API, it states the following error message. Location track must be less than 1 degrees on a side: LocationTrack(48.77,-9.05,58.88,2.19) I can't imagine that Twitter do not allow you a specify a bounding box that covers an area that crosses between the negative/positive LAT. Am I missing something here, or would this mean that Twitter only allow you to stream if you are in the Wester hemishphere, effectively? If anyone has a suggest as to how I might be able to over-come this, I'd be very interested in hearing you out.

Just a thought, but the error says that the bounding box must be at most one degree on each side... and that box is about 11x10. It does seem like a bit of a restriction, but still... D

If you need larger bounding boxes, you can request a higher access level. You can also assemble a number of smaller bounding boxes into a larger box to cover more area. So, you can divvy up your allocation into a contiguous area, or multiple discontinuous regions. If there's a bug on creating a legally-sized bounding box that straddle one or both of the prime meridian or the equator, we'll certainly fix that. Given the proportion of geo-tagged tweets, perhaps we should indeed make these boxes bigger for the default access role. -John On Wed, Jul 21, 2010 at 8:08 AM, Dave Ingram d...@dmi.me.uk wrote: On 07/21/10 15:13, James wrote: I'm attempting to stream Tweets from the UK as a whole(filtering further with tracking words), using Twitters stream API, however I'm having trouble with my bounding box.

Quoting John Kalucki j...@twitter.com: Given the proportion of geo-tagged tweets, perhaps we should indeed make these boxes bigger for the default access role. Any numbers you'd be willing to share? I'd hate to see you go with bigger boxes only to have to shrink them again when location picks up in Twitter hot-spots like PDX and SFO. Spritzer dropping from 5% to 1% is kinda fresh in my mind. ;-) -- M.
