[mapserver-users] RE: Documentation for serving large raster images using tile cache.

[Asif Memon]

Hello,

 

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. Any help is greatly appreciated.
Thanks! 

 

Sincerely,

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.


But you may want to install OpenLayers and get it working with MapServer 
first, then hit up the OL and TC mailing lists.

Hi Asif,

Best thing to do is take a look at these 2 docs first:
- http://mapserver.gis.umn.edu/docs/howto/raster_data
- http://tilecache.org/readme.html

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.

Hi Asif,

Are you able to view a map when you go to "
http://localhost:9090/cgi-bin/mapserv.exe?map=/path/to/itasca.map&mode=map";
?  Also, can you send a copy of your mapfile, and of your tilecache.cfg
files?

[Asif Memon]

Thanks for your reply.

 

Attached is the map file. I do not have the any tilecache.cfg file. From the 
error(msLoadMap(): Unable to access file. (/path/to/demo.map)), it appears the 
map file is not accessible.

RE: [mapserver-users] RE: Documentation for serving large raster images using tile cache.

[Asif Memon]

I believe one of the "END" was missing at the end of the file, I have added 
that. This resolves the earlier error and generated a new one - msDrawMap(): 
Image handling error. Unable to initialize image. msPrepareImage(): General 
error message. Image dimensions not specified. msCalculateScale(): General 
error message. Invalid image extent, minx=-1.00, miny=-1.00, 
maxx=-1.00, maxy=-1.00. mapserv(): Web application error. No way to 
generate map extent.

 

Any help is much appreciated?

No, TileCache didn't come with that. I am trying to view any image right now to 
see an example of serving an image into Mapserver. 

 

I changed the path of the WMS 
URL(http://localhost:9090/cgi-bin/mapserv.exe?map=C:\Asif\work\devtools\MMS\ms4w\Apache\htdocs\mapdemo\demo.map&mode=map)
 and the error I am getting now is - msLoadMap(): Premature End-of-File.

 

I ran the GDAL tile cache command on a .tif image to create the shape files 
using (gdaltindex doq_index.shp doq/*.tif). Also, I made some changes in the 
map file. Attached is the most updated map file along with the shape files. 

 

Could you please take a look at it.

RE: [mapserver-users] RE: Documentation for serving large raster images using tile cache.

[Asif Memon]

Thanks Roger. 

 

I don't see any errors now, but no image appears in the browser(the browser is 
blank). I made minor changes to the map file that you sent me (about the paths, 
attached is the file).  

 

The URL that I am using in the browser is 
http://localhost:9090/cgi-bin/mapserv.exe?map=C:\Asif\work\devtools\MMS\ms4w\Apache\htdocs\mapdemo\itasca_demo.map&mode=map

 

Please correct me if anything is wrong in the URL or in the map file. 

 

Sincerely,

Asif Memon

Hi Asif,

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,
DATA "/var/www/mapfiles/itasca/demo.tif"

and also changed the EXTENT to this:
  EXTENT  -0.9194182 -4.2013292 -0.9002422 -4.1870152

This matches the extent of the file when you run gdalinfo against it (min_x
min_y max_x Max_y).

With these changes, I'm able to view the file with the following URL:
http://localhost/cgi-bin/mapserv?map=/var/www/mapfiles/itasca/itasca_demo.map&mode=map

(Note, I'm running this in Linux, so paths and URLs are going to be slightly
different than yours)

Try changing your EXTENT entry to match mine, that might do the trick.

Hi Roger,

 

It works, thanks a lot.

 

I want to create the image tiles for this image. I was looking at GDAL 
utilities for this. Do you know how to do that? 

 

Sincerely,

Asif Memon

I don't see any errors now, but no image appears in the browser(the browser is 
blank). I made minor changes to the map file that you sent me (about the paths, 
attached is the file).  

 

The URL that I am using in the browser is 
http://localhost:9090/cgi-bin/mapserv.exe?map=C:\Asif\work\devtools\MMS\ms4w\Apache\htdocs\mapdemo\itasca_demo.map&mode=map

Please correct me if anything is wrong in the URL or in the map file.

Hi Asif,

Ok, here's a new mapfile that you can try.  Change your request to point to 
this one, and see if you get an image back in your browser.

No, TileCache didn't come with that. I am trying to view any image right now to 
see an example of serving an image into Mapserver. 

 

I changed the path of the WMS 
URL(http://localhost:9090/cgi-bin/mapserv.exe?map=C:\Asif\work\devtools\MMS\ms4w\Apache\htdocs\mapdemo\demo.map&mode=map
 
<http://localhost:9090/cgi-bin/mapserv.exe?map=C:%5CAsif%5Cwork%5Cdevtools%5CMMS%5Cms4w%5CApache%5Chtdocs%5Cmapdemo%5Cdemo.map&mode=map>
 ) and the error I am getting now is - msLoadMap(): Premature End-of-File.

 

I ran the GDAL tile cache command on a .tif image to create the shape files 
using (gdaltindex doq_index.shp doq/*.tif). Also, I made some changes in the 
map file. Attached is the most updated map file along with the shape files. 

 

Could you please take a look at it. 

 

Sincerely,

Asif Memon

Sorry I assumed that the index.html file was the one that came with TileCache.  
Is that not correct?

Attached is the map file. I do not have the any tilecache.cfg file. From the 
error(msLoadMap(): Unable to access file. (/path/to/demo.map)), it appears the
