Re: [mapserver-users] changing projection
You will need to specify the projection of the source data in each of the layers and then specify the output projection you wish to have at the map level and mapserver will reproject your data on the fly. Note that you need to set your extent and units at the map level appropriately to the output projection. For instance, if your source data is in lat/lon (decimal degrees) you would be using UNITS DD but if you change to output the projection below, you would need to change to UNITS METERS Cheers Paul On 15-Jul-08, at 6:36 PM, boice tomlin wrote: Hello, We are using mapserver version 4.10 and in our mapfile we don't specify a projection at the map level or in any of the layers.

Re: [mapserver-users] WMS raster display, getfeatureinfo from vectorlayer
status: RESOLVED
I spent a little while trying to get a mapscript wrapper to work...
Getcapabilities and getfeatureinfo worked fine, but never got an image out.
We ended up solving the problem this way:
Created two mapfiles called GMNA_OWS_display.map and GMNA_OWS query.map
One identically named layer in each file, Geologic_Map_of North_America
Display mapfile has layer set to RASTER, with a template set to
null.html so that the layer advertises itself as queryable.
Query mapfile has layer set to polygon and points to the vector data,
and has all of the template parameters set appropriately.
With HTACCESS turned on for that folder, a mod_rewrite section in the
.htaccess file looks for the getfeatureinfo string and the mapfile named
display and substitutes the query mapfile, actual code below:
---htaccess file--
RewriteEngine on
RewriteCond %{QUERY_STRING}
^[A-z0-9,.%/-?&=]+GetFeatureInfo[A-z0-9,.%/-?&=]+
RewriteCond %{QUERY_STRING} ^(.*)GMNA_OWS_display(.*)
RewriteRule ^.*mapserv.cgi.*$
/cgi-bin/mapserv.cgi?%1GMNA_OWS_query%2[L]
-end of htaccess--
I hope this helps someone else for future reference, and thanks for the
help,
Percy

I discussed this issue with Tom K. on the IRC yesterday, and he

Scenario: we have a Geologic map that has super complex cartography
that we don't want to reproduce in the mapfile (600+ classes, tons
of patterns, etc). So we dumped out a raster of it to serve as WMS.
However, when the user does a GetFeatureInfo on this WMS, we want to
return attribute data from the original shapefile.
I can envision this being taken care of at the layer level as a
metadata tag like "WMS_query_redirect".
In the short term we're working on a little apache mod_rewrite magic
to take care of it :-)

Unrelated to the original question, but: If by 'XML declaration', you mean 'XML prolog', it is not required to be included in XML. If you do not include one, the encoding typically defaults to UTF-8, however, which is likely a problem if you have iso-8859-1 encoded attribute data -- but since I don't think MapServer has any way of knowing the encoding of your data, including one probably doesn't help much anyway.

Re: [mapserver-users] mapscript queryByPoint - tolerancedepends ofresolution ?
Hi The problem was not in mapserver but came from our script: when the dpi is changed, the tolerance is globaly adjusted so all the related features dont get over/undersized. But when a value of -1 is used in queryByPoint, the global tolerance recalculated result in -3.25~ when passing from 96 to 150 dpi and mapserver do not know what to do with such value, it only understand -1 or >=0. The problem was solved by specifying a special case when -1 was used in our script for queryByPoint, so the tolerance stay at -1 at 96 and 150 dpi Could you possible modify a bit the mapscript documentation of queryByPoint ? It say "Passing buffer <=0 defaults to tolerances set in the map file ..." but thats not exactly the case. It would be "Passing buffer -1 defaults to tolerances set in the map file..."

Tolerance computations are based on cellsize. Resolution affects only scale computations, so it is not clear to me how one could affect the other. I just went through the code to verify. Is there any chance that layer scale limits are coming into play here and you're not querying the layer you think you are? Does the behavior persist in 5.x?

The result obtained is the area containing the coordinates I used, it's absolutly normal and I get what I expect. Now, if I dynamicaly change the resolution of the map to 150 dpi and then do exactly the same queryByPoint as before, I get nothing! Mapserver consider there was nothing at the coordinate I provided.
