Something like: PROJECTION init=epsg:4326 END The Projection block in the MAP section defines your output projection. Because your data is not in the same projection, you will need to define a projection block in each layer section. Those projection blocks define the ‘input’ projection.

Re: [mapserver-users] Re: Raster dataset recommendations
I would agree with Edi and recommend TIFF. It's easy to move around and deal with, and is the fastest of the raster formats. (unless something new has come up?) I would also agree with Mark: a tileindex is for mosaicing many TIFFs, and if your result is 1 single TIFF the tileindex is unnecessary. Edi's recommendation about a internal tile is VERY important. It costs slightly more disk space, but makes a tremendous improvement in the random access within the TIFF's extent. The overviews accomplish a similar performance gain, but for views in which the TIFF's extent is only a subset of what's showing on the map. -- HostGIS, Open Source solutions for the global GIS community Greg Allensworth - SysAdmin, Programmer, GIS Person, Security Network+ Server+ A+ Security+ Linux+ PHP PostgreSQL MySQL DHTML/JavaScript/AJAX No one cares if you can back up — only if you can recover. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

[mapserver-users] REST and SOAP in Mapserver
Is it possible to consume REST and/or SOAP services in Mapserver somewhat like WMS and how? ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] Re:REST and SOAP in Mapserver
Eric, Several years ago I did some experimental work with SOAP and REST inside the mapserv engine. The archives may contain a few old messages about the details, but what I was doing was to consume (now defunct) ESRI ArcWeb Services map images as raster backdrops for added mapserver vector layers. I created CONNECTIONTYPE ARCWEB and associated mapserver mapfile constructs to ArcWeb params. The communication part was fairly easy to deal with: I refit the existing OWS cURL code to access the ESRI server. The construction of the SOAP xml was cumbersome. The image that came back was slipped into the existing raster output mechanism. When I revisited the project a year or so later, I decided it was best to stay OUT of mapserv cgi and opt instead for doing the work in php-mapscript, where the SOAP processing is more advanced. Also, as I see it, the main problem of trying to consume SOAP and REST services in mapserver is simply that it is difficult to anticipate what kinds of functions you are going to be using to access the SOAP/REST server, so there's no generic way to associate mapfile constructs to the foreign parameters, and there's no way to make the construction of SOAP/REST requests generic either. If someone REALLY needed to do this within mapserv cgi, there might be some way to have WSDL-processing to make things more generic, but I'd be skeptical about the success of such a venture.

Re: [mapserver-users] Raster dataset recommendations
Hi, Thanks for these advises! I take the opportunity of this topic to ask a similar question. I have a larger data set (400 Go) in about 24000 GeoTIFFs files, using the method described by Edi (tiled, internal overviews, index shape). It works pretty well (older version of MapServer), with on-the-fly reprojection, quick enough when the resolution is small-enough. My first question is about the right tile size. What should I take into account to seek the right balance between many small files and fewer bigger files? With too many files, I guess I should build external overviews as well. Also, do the 24000 files make a performance penalty for file access (stat() call)? Are TFW files checked even with geocoded tiffs? Second question: what about WKT raster, or the new raster support within PostGIS? I would love to use it, for the power of SQL queries. Is it really slower than GeoTIFF? Is it well suited for very large datasets? Any advise on this would be very helpful. Thanks!

[mapserver-users] Re: Raster dataset recommendations
Jean, thats my problem too. I haven't resolved it yet the perfect way, but i have created mosaics of the data with lowered resolution, and a lower number of tiles . The number of tiles that are requested to see the map increases when you zoom out, so it needs to seek and read the tiles. Having them in different HD will make the displaying of the map faster because you will have more than one hd that does the seek/read process. The idea is that in your zoom levels you dont need more than four tiles to display the image. So youll have to calculate the mapserver resolution, image resolution and map control size. I have more than 3 terabytes of data in 15000 tiles and i created another mosaic with 1.5 terabytes and ~ 4000 tiles. And so on. My main problem is determining the scale when to switch from one mosaic to the other and i resolved it with testing the speed of the response. Maybe this time someone will have an idea to this post. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Raster-dataset-recommendations-tp6064491p6066256.html Sent from the Mapserver - User mailing list archive at Nabble.com. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
