[Talk-us] Updated: ITO image of 'a year of edits' for North America

[Peter Miller]

We have updated the 'year of edits' image on Flickr for North America  
and it is very impressive what is happening there. Lights are coming  
on all over the place!

Do zoom in on areas of the US and then to some cities where we also  
have updated images and check out other parts of the world in the  
'from time to time' set.



Regards,




Peter Miller

 You can check out the NAIP imagery to see if there're more recent data in
 your area
 http://www.fsa.usda.gov/Internet/FSA_File/naip03-08cov_maps.pdf which is
 downloadable at http://datagateway.nrcs.usda.gov/GatewayHome.html it would
 be pretty easy to setup a WMS server for use in JOSM and Merkaartor.
 The 1m imagery in this area (I think it's 1m, personally) is superior to
 the available yahoo imagery, though it is somewhat halo-ey

Thanks for the pointer to the NAIP images...  The GIS department at
ISU has the NAIP images for Iowa up on a WMS server[1] but I've never
been able to access it... maybe I never tried hard enough or maybe
their WMS server is a little different and I don't know what the right
magic incantation is...  Anyway,  I've spent some time recently to
download some of the NAIP images and set up a test WMS server using
the UofM mapserver software.  After a few trials and tribulations,
I've got something working that I can use.  The georeferencing of the
NAIP images seems to be better than the Yahoo images from what I can
tell and the NAIP images provide a consistently high resolution for
all of the areas that I've looked at.  The best of the Yahoo images
look better than the NAIP images, but Yahoo only covers major metro
areas with high resolution data.  With the NAIP images I've finally
been able to do some armchair mapping of my hometown, which only had
low-res imagery available from Yahoo.

It's also extremely nice to have images that are much more recent than
Yahoo offers...

Anyhoo... The server that's running my WMS is a virtual guest borrowed
from work, so it doesn't have a lot of oomph and I'll have to turn it
off eventually.  That said, if we can agree on an area to map for our
online mapping party I'll load the appropriate NAIP images onto the
server and share the URL to the server with those interested in doing
some mapping.
