##ofapp-GoogleStreetView

This is a simple openFrameworks app that shows you how to grab high res tiles from Google Street View.

So you run an HTTP GET to this address: "http://cbk0.google.com/cbk?output=xml&ll=33.748302,-84.397306" with the ll=LONG,LAT in this case we are looking at Magic City an infamous strip club in Atlanta Georgia.

It returns something that looks like this:

			<panorama>
				<data_properties image_width="13312" image_height="6656" tile_width="512" tile_height="512" image_date="2008-03" pano_id="sLaiF6Jex7mJmNol7tdOoA" num_zoom_levels="3" lat="51.495078" lng="-0.147004" original_lat="51.495073" original_lng="-0.146987" best_view_direction_deg="113.528">

				<country>United Kingdom</country>
				<data_flag>1</data_flag>
				</data_properties>
				<projection_properties projection_type="spherical" pano_yaw_deg="204.15" tilt_yaw_deg="-17.52" tilt_pitch_deg="0.75"/>

				<link yaw_deg="25.37" pano_id="t_mnKSugTLrQTEnJplXQ3A" road_argb="0x80ffffff" scene="0">
				<link_text>Ebury Street / Eccleston Place</link_text>
				</link>
				<link yaw_deg="205.51" pano_id="x8-xIY7hWYkqrVqoePGdJQ" road_argb="0x80ffffff" scene="0">
				<link_text>Eccleston Place</link_text>
				</link>
			</annotation_properties>
			</panorama>

You are looking for the pano_id="sLaiF6Jex7mJmNol7tdOoA"

You then issue a HTTP GET to this address: "http://cbk0.google.com/cbk?output=tile&panoid=PANOID"&zoom=ZOOMLEVEL&x=XX&y=YY"

where

	PANOID = pano_id from the panorama XML

The zoom level

	zoom = 0 || 1 || 2 || 3 || 4 || 5 

	if zoom = 0, X=0 and Y=0

	if zoom = 1, X = (0-1) and Y = 0

	if zoom = 2, X = (0-3) and Y = (0-1)

	if zoom = 3, X = (0-5) and Y = (0-2)

	if zoom = 4, X = (0-12) and Y = (0-6)

	if zoom = 5 X = (0-25) and Y = (0-12)

Currently this App is set to use zoom level 3.
