[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=-1.000000, miny=-1.000000, maxx=-1.000000, maxy=-1.000000. mapserv(): Web application error. No way to generate map extent.

 

Any help is much appreciated? 

 

Sincerely,

Asif Memon

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. 

 

Sincerely,

Asif Memon

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

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.

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?

Hi Roger,

 

I followed the instructions on the documentation and setup the map server and demo, when I try to execute the index.html, I get this error - msLoadMap(): Unable to access file. (http://localhost:9090/mapdemo/itasca.map)

 

Do you know what could be it? 

 

Sincerely,

Asif Memon

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.

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.
