<p class="MsoNormal"><span style="font-size: 10pt; font-family: "Calibri","sans-serif"; color: blue;">I want to ask a question about the NASA Global Mosaic and how it
doesn’t match up with the data at a statewide zoom and and farther
out. I added a layer EROS that uses the projection 4326 and added it
similarly to the mapbook.xml as the global mosaic. At the statewide zoom,
the images and the county layers do not match up. As you zoom in, the lines
approach the correct placement on the map.</span></p>

Efstathios Arapostathis remarked about having problems with this also. I
just installed GM 2.0.1 yesterday and had only made changes to the mapbook.xml
by adding some layers.</span></p>

<p class="MsoNormal">First off, thank you to everyone who has helped my
application get this far.<br>
<br><span>
As with the demo, I am trying to use the NASA global mosaic in my geomoose
application, but I may be having some problems with projections. I have
defined EPSG:3071, which is the Wisconsin Transverse Mercator <a target="_blank" href="http://www.spatialreference.org/ref/epsg/3071/">http://www.spatialreference.org/ref/epsg/3071/</a>
and all of my own data is in this projection, but the global mosaic does not
recognize it. When I leave the wms in EPSG:4326 the image shows up, but
it matches the map less and less at smaller scales. This can be seen on
the demo here: <a target="_blank" href="http://gis.swwrpc.org/geomoose2/geomoose.html">http://gis.swwrpc.org/geomoose2/geomoose.html</a>
(zoom in and it looks ok, but zoom out and it is way off).</span><br>
<br>
I see that the default projection for the global mosaic is EPSG:4326, does this
mean that I cannot reproject it in geomoose 2.0?<br>
<br><span>
I followed the instructions here: <a target="_blank" href="http://www.geomoose.org/moose/howto/wms_project.html">http://www.geomoose.org/moose/howto/wms_project.html</a>
but to no avail, which makes me believe it could be a problem with my
configuration somehow. Should I instead write a mapfile to take the wms?</span><br>
<br>
Here is the code from my mapbook (with the default projection):<br>
<map-source name="nasa" type="wms"
tiled="false" projection="EPSG:4326"><br><span>
<url><a target="_blank" href="http://wms.jpl.nasa.gov/wms.cgi">http://wms.jpl.nasa.gov/wms.cgi</a></url></span><br>
<layer
name="global_mosaic"/><br>
<param name="format"
value="image/jpeg" reproject="true"/><br>
</map-source><br>
<br>
...and here is my projection:<br>
Proj4js.defs["EPSG:3071"] = "+title= NAD83(HARN) / Wisconsin
Transverse Mercator +proj=tmerc +lat_0=0 +lon_0=-90 +k=0.9996 +x_0=520000
+y_0=-4480000 +ellps=GRS80 +units=m +no_defs";<br>
<br>
<br>
Thank you all for your help</p>
