 Let me revisit this this radius option again for just a second. You need to be mindful about what you set this at in terms of how large the number is or how small the number is and you need to need to associate that with the relative size of the population center you're dealing with. For instance if you run a radius of one kilometer and you do it in downtown Manhattan you're going to end up with thousands upon thousands of media responses so much so that most of the APIs restrict the amount they can respond with and so you'll only get back a subset of the actual number of pieces of media that exist and you end up with a false negative situation where you didn't actually get all the data that you should have gotten because you set your radius too large. On the other hand be careful about setting the radius too small. Some of these resources will accept numbers less than one such as point one or point zero one kilometers. However I have seen where resources that do not support numbers less than one end up defaulting to a higher number something is 10 something like 10 or 50 or 100 kilometers and that will introduce a false positive situation where you end up getting back a bunch of responses that are outside the collection radius that was defined.
