<DIV>Thanks for the info and examples Dorothy. </DIV>

<DIV>As a related FYI about the 2009 imagery, in case folks missed it, Erik posted an Imagery Update from Geo message on GovSpace last month following the GPL discussion about the service(s) status. <A href="https://govspace.oregon.gov/community/agencies/das/geo/gpl/blog/2011/06/17/imagery-update-from-geo">https://govspace.oregon.gov/community/agencies/das/geo/gpl/blog/2011/06/17/imagery-update-from-geo</A></DIV>
<DIV> </DIV>
<DIV>In the details, Erik notes that the 2009 WM is only cached to 1:36K (which is why Dorothy's example looks so bad). This is confirmed when you examine the REST endpoint for the service as the largest available scale is 1:36111. On the other hand the 2009 ORLAM is also 1:36K statewide but 1:2256K in PDX though Erik notes that he plans to do the whole state at this scale. So scale 1:2256 shows up via the REST endpoint even if the tiles aren't available everywhere.</DIV>

<DIV><FONT size=2 face=Arial><SPAN class=416211415-20072011>Here are some examples of being able to zoom in with the aerial photos. It would be wonderful if the ESRI service would allow one or two more zoom levels in the rural areas. If there are any other web services I should be aware of (using projection 102100), please let me know.</SPAN></FONT></DIV>
