You can gladly have the CalcLonLat() function to look at / use if it helps (the object is still subject to change). The t@h gets a bigger box to account for rendering things close to the edge etc, but if you specify the exact bounding box any way that has any node in the box is retrieved completely. <br><div> </div>cheers,<br>Chris<div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><br><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">----- Original Message ----<br>From: Jeremy Adams <milenko@king-nerd.com><br>To: talk@openstreetmap.org<br>Sent: Thursday, 17 January, 2008 8:55:15 PM<br>Subject: [OSM-talk] z12 bounding
box<br><br>

<div><font face="Arial" size="2">Is there an easy way to figure out what the
equivalent bounding box of a particular tile would be? </font></div>

<div><font face="Arial" size="2">For instance, I want to use osmosis to cut out a
bounding box that contains all the info in a particular z12 tile (or any
zoom). How would I figure out what the lon and lat values would be for the
tile?</font></div>

<div><font face="Arial" size="2">I'm guessing it's possible since the <a rel="nofollow" ymailto="mailto:t@h" target="_blank" href="mailto:t@h">t@h</a> client does it when it requests data from the API, but
I'm not clear on how it works.</font></div>
