<p class=MsoNormal style='margin-bottom:12.0pt'>Hi Asif,<br>
<br>
My apologies. I saw your message Friday evening but forgot about it over
the weekend in the course of reinstalling my Linux OS. If time is of the
essence, posting your question to the entire list should ensure a speedier
response. <br>
<br>
Regarding your questions:<br>
<br>
1) I am not aware of any applications that will act as viewers for Mapserver
operating in "map" mode. They may exist, but I'm not familiar
with them. I tend to use Mapserver in only one of two ways at the moment;
in "map" mode to generate static maps, in "wms" mode with a
connection to it via OpenLayers (or TileCache).<br>
<br>
2) Regarding the path to your mapfile, I believe there are several solutions
that you can try if your goal is to shorten the URL string. They are
well-explained here - <a
href="http://mapserver.gis.umn.edu/docs/howto/wms_server/#more-about-the-online-resource-url">http://mapserver.gis.umn.edu/docs/howto/wms_server/#more-about-the-online-resource-url</a>.
As far as why the 1st URL doesn't actually work, it's because the path should
be relative to the mapserv.exe location in cgi-bin, not to htdocs. So try
this instead:<br>
<br>
- <a
href="http://localhost:9090/cgi-bin/mapserv.exe?map=/mapdemo/itasca_demo.map&mode=map"
target="_blank">http://localhost:9090/cgi-bin/mapserv.exe?map=../htdocs/mapdemo/itasca_demo.map&mode=map</a><br>

<p style='margin-bottom:12.0pt'>Hi Asif,<br>
<br>
I downloaded the demo.tif file that you sent earlier, and the itasca_demo.map
from you rprevious email. I changed the path in the DATA portion of the
LAYER section to point to my filesystem, <br>
DATA "/var/www/mapfiles/itasca/demo.tif"<br>
<br>
and also changed the EXTENT to this:<br>
EXTENT -0.9194182 -4.2013292 -0.9002422 -4.1870152<br>
<br>
This matches the extent of the file when you run gdalinfo against it (min_x
min_y max_x Max_y).<br>
<br>
With these changes, I'm able to view the file with the following URL:<br>
<a
href="http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/itasca/itasca_demo.map&mode=map"
target="_blank">http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/itasca/itasca_demo.map&mode=map</a><br>
<br>
(Note, I'm running this in Linux, so paths and URLs are going to be slightly
different than yours)<br>
<br>
Try changing your EXTENT entry to match mine, that might do the trick.<br>

<br>
Best thing to do is take a look at these 2 docs first:<br>
- <a href="http://mapserver.gis.umn.edu/docs/howto/raster_data" target="_blank">http://mapserver.gis.umn.edu/docs/howto/raster_data</a><br>
- <a href="http://tilecache.org/readme.html" target="_blank">http://tilecache.org/readme.html</a><br>
<br>
Once you have the ability to see your raster in MapServer via a
"mode=map" request, then you will have to decide how you wish to view
your data afterwards. There are different things to do in TileCache
depending on whether you wish to view the data in OpenLayers, or over Google
Maps/MS VE.<br>

<p>Could someone please point me to the documentation for serving large (2GB to
3GB) raster images using tile cache. I want to use Minnesota Map Server and
GDAL to achieve this.<o:p></o:p></p>

<p>You'll want to ask the TileCache list about that, likely. Once you have
MapServer actually serving up the imagery, get your client using MapServer or
WMS (I like OpenLayers, myself). Then install TileCache and change the OL app
to use TC's URL instead of MapServer's. Easy.<br>
<br>
But you may want to install OpenLayers and get it working with MapServer first,
then hit up the OL and TC mailing lists.<br>
