Hello,
Has anyone else printed out any of the new US Topo (digital) maps? I
hope I am wrong, but it looks like the UTM northing grid for the three
maps we tested Lexington West, KY; Olmstead, ILL/KY; Wolf Creek Dam, KY)
is off by about 200 meters. I am ready to notify the USGS so they can
check this out, but would like to see if this is in fact a real problem.
Can anyone confirm this?
Thanks,
-Greg

Hello Everyone,
Ok, we figured out the problem with printing. We did a Print setup
first, then printed the map using custom dimensions. The scale seems to
be ok now, but there still seems to be something funny going on with the
UTM grid. The easting grid ticks look ok, but the northing grid is off
by about 200 meters for the following quads we tested:
Lexington West, KY
Olmstead, ILL/KY
Wolf Creek Dam, KY

Hi Everyone,
I think the reason for the difference in accuracy between maps is
explained here at this link http://nationalmap.gov/ustopo/about.html
where it says:
The quality and accuracy of an individual US Topo map depends on The
National Map data used to make it. The file format is a georereferenced
GeoPDF(r). US Topo users can interact with map features using free
PC-compatible software. The map files are available, at no cost, for
digital download from the USGS Store.
Draft Standard: US Topo - Version 0.5.10 (November 2009)
Draft Standard: "Digital Map - Beta" - Version 0.0.25 (July 2009)

Hello All,
Please forgive the typo at the end of the last bullet "We measured".
Some additional things we noticed:
When we measured both the Wolf Creek Dam and Lexington West quads, the
2010 US Topo coverage area is wider and longer than the older USGS topo
maps, and the grid and scales don't match. This is really strange.

Hello,
Has anyone tried to print 2010 US Topo PDF's using Adobe Reader? We
tried printing Wolf Creek Dam, KY and Lexington West. KY. We noticed the
following when printing on our HP wide format plotter:
- With all of the layers turned on, the map looks nice, but the ortho
image seams to drown out the contour lines.
- With the ortho image turned off, the map prints nice, but there is no
building layer or shaded layers available to show wooded areas,
populated areas, and road layers are labeled very little in the
populated areas.
- The map prints larger than an original paper map even after we set the
print size to the size of the exact map dimensions. For example, we set
the print size to 29.00 x 22.75. but it still printed a map 33.11 x
23.39. We measured
Has anyone had the same problem or noticed any of these things?
Thanks,
-Greg
