[Mapserver-users] reprojection, expressions, and query blues

[Gustavo Alcides Concheiro Perez]

Newbie questions, I expect:

1. I'm trying to reproject some shapefiles.  I set the projection for the 
layers (lat/long) and the (different) projection for the map (like LAEA---I 
tried several)  AFAIK the proj codes are correct, and I copied the tutorials 
code as models.   NOTHING HAPPENS.  Layers are *not* reprojected but shown in 
lat/long, and no error message pops anywhere, even when I use "DEBUG ON" on 
layers.  I'm totally baffled.

2. Same thing with passing a expression in the URL.  Nothing happens; no error 
message either.

3. I want the elevation for the query point.  This is very important.  I have 
the DEMs (several), but I see no way to query a raster file with MapServer.

4. Is there a way to link tolerance (for mouseclicks on queries) to mapa units 
(e.g. 10 km radius) instead of just pixels?


I'm using version 4.2. as CGI.


5. Finally, is there any tutorial that explains *concepts* and *strategies* on 
how to do this, the *rationale* of it, and not just keyword references for 
the code and map examples with pieces of code?  I must confess that after 
quite a bit of RTFM, I still can't really understand how to use MapServer.


TIA.
