title: Panorama IDs of All Street View Panoramas in Area (Street View Image API)
body: <p>I've been working on a novel use of the <a href="https://developers.google.com/maps/documentation/streetview/" rel="nofollow noreferrer">Google Street View Image API</a>, but I keep running up against limitations in my dataset. Specifically, I'm interested in downloading parts of every Street View panorama in a given bounded geographical area, but I can't find a good way to obtain a list of the panoramas in that area first.</p>
  
  <p>What I've been doing so far is to call <code>streetview/metadata</code> using a whole bunch of co-ordinates that are regularly placed (e.g. on a 1m grid), and then de-duplicating the returned panorama IDs. This is obviously sub-optimal, as it requires a huge number of network calls and is still prone to missing panoramas.</p>
  
  <p>Does anyone have any better ideas? Is there another endpoint that I don't know about that I could use, or some workaround that would enable the retrieval of multiple panorama IDs at once?</p>
