<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The USGS Urban Area orthophotography is a
data set that started out very homogeneous and consistent, and is rapidly
developing into quite an assortment of data in various resolutions, color
formats, and projections. The original image tiles themselves are either in
UTM or various State Plane coordinate systems, so they are not rectangles in
lat/lon space. I’ve developed a set of index shapefiles for this data
for just the purpose you describe – we serve this data set on TopoZone
and use the shapefiles to indicate through the UI whether there’s
high-resolution imagery at any given location. But these are indexes for our
versions of these data sets, not the seamless.usgs.gov data (we don’t use
their WMS service, but host and serve the imagery ourselves). They wouldn’t
be useful since they don’t accurately describe the data you’re
viewing.<o:p></o:p></span></font></p>

10.0pt;font-family:Arial;color:navy'>I think you’ll have to see what you
can find from the USGS, since they’re the only ones who can accurately
describe the current subset of this data set that’s available on
seamless.usgs.gov at any given time. Good luck!<o:p></o:p></span></font></p>

in shapefile (or WKT etc.) format. I could only found the coverage index in
raster format on the USGS site (seamless.usgs.gov) I'd like to be able to tell
having a lat/lon coordinates whether it falls into one of the Urban coverage
areas. The USGS WMS server provides boudary rectangle only (in
GetCapabilities), which obviously will not solve my problem as the coverages
are not rectangles.<o:p></o:p></span></font></p>
