Re: [mapserver-users] Access control for wms served from mapserver cgi
Hello Rahkonen (and Stephan), This is an idea that I could make work...I'd have to lock-down mapserv itself from all connections (otherwise anyone could just replace wms*.exe in the URL with the original mapserv.exe), though I guess I should be doing that anyway. In response to Stephan Holl: I recognize there are other strategies that involve proxying the WMS requests. I was just hoping for something quick and easy that could be done with Apache more or less out-of-the-box using basic config files and/or modules like mod_rewrite. There have been a few cases where I needed to use mapserver on one machine to serve data using WMS to another server running mapserver as a WMS client. I just want to be able to do that with as little work as possible (i.e., if I can do it in Apache's config, then I can do it anywhere). Essentially, my ideal solution would be if I can get something like mod_rewrite to say if a request to mapserv contains 'map=/path/to/somefile.map' in the query string, and the client is not equal to some IP address, return 403, otherwise allow the request. I just don't quite know how to get mod_rewrite to work like that for me (I found some promising examples online, but couldn't get them working). Thanks again, Mike Rahkonen Jukka wrote: Hi, If it is easy to limit access to mapserv executable, then how about making a few copies of the executable and tie each copy to its own mapfile in httpd.conf?

Re: [mapserver-users] Fractional line widths?
Hello Dane, If you change the name of your OUTPUTFORMAT to 'AGGA', then I think you must also change the IMAGETYPE parameter to 'AGGA' so that the map uses the correct outputformat (i.e., there can be more than one outpuformat in a mapfile). Mike Date: Thu, 4 Sep 2008 19:10:53 -0700 From: Dane Springmeyer [EMAIL PROTECTED] Subject: Re: [mapserver-users] Fractional line widths? To: thomas bonfort [EMAIL PROTECTED] Cc: mapserver-users@lists.osgeo.org Message-ID: [EMAIL PROTECTED] Content-Type: text/plain; charset=us-ascii Thomas, Thanks for the tip, but I think I don't quite understand the right syntax. First of all, I'm running the mac binary from kyngchaos, version 5.2.0 I've tried to add two style blocks like: LAYER NAME world_opacity DATA world_borders.shp STATUS ON TYPE POLYGON CLASS NAME World STYLE COLOR 242 239 249 OUTLINECOLOR-1 -1 -1 END STYLE COLOR -1 -1 -1 OUTLINECOLOR 127 127 127 OPACITY 50 WIDTH 1 END END # class END # layer to create this full mapfile: http://mapnik-utils.googlecode.com/svn/trunk/tutorials/hello_world/mapserver_comparison/mapfile_config/world.map But that does not produce a result more akin to WIDTH 0.5, from what I can tell. It simply lightens the color of the outline, and in this case make it 'seem' even thicker. It is as if the opacity is not working as a true alpha opacity. Here is the example output with OPACITY 50: http://mapnik-utils.googlecode.com/svn/trunk/tutorials/hello_world/mapserver_comparison/mapfile_config/map/hello_world_with_mapserver_mapfile_opacity.png Is this the expected behavior or have I made an error in my mapfile syntax (highly likely). Perhaps I am not correctly turning off the outline for the first style? The issue may also be with my OUTPUTFORMAT, which is not using the RGBA: OUTPUTFORMAT NAME 'AGG' DRIVER AGG/PNG IMAGEMODE RGB MIMETYPE image/png END I also tried with: OUTPUTFORMAT NAME 'AGGA' DRIVER AGG/PNG IMAGEMODE RGBA MIMETYPE image/png END but I get an error when I add the 'AGGA' (based on reading http://mapserver.gis.umn.edu/docs/howto/agg-rendering-specifics) : msPostMapParseOutputFormatSetup(): General error message. Unable to select IMAGETYPE `AGG'. Any thoughts?

Re: [mapserver-users] Corrupt image output (solved?)
Hello again, I think I found the cause of my problem - on my server (where I had preprocessed all of my imagery), I have libgeotiff-1.2.4 installed from the F8 repositories. On my laptop I had libgeotiff-1.2.3 installed from source. I upgraded my laptop to libgeotiff-1.2.4 (I tried 1.2.5, but it didn't compile for me), and recompiled gdal and mapserver. Now it seems that imagery renders okay (after some quick tests). I didn't realize I had different libgeotiff library versions...but it also hadn't occurred to me that a GeoTiff dataset might be incompatible with different versions of libgeotiff. So should I maybe close the ticket that I opened earlier today? Mike Mike Leahy wrote: Ok, I'll file a ticket shortly...but I have a few more things I've tried that might add insight to this. It seems if I load the map via cgi mapserver, I get the same problems - so this isn't limited to mapscript. In contrast, I don't seem to have any trouble with the output values if I extract a single pixel from an image using gdal_translate to a *.grd file (at the same coordinates where I get corrupt results from mapscript/mapserver) - so the problem doesn't seem to be with gdal by itself. Also, I can point out that the corrupted areas in the output have no coincidence with tile-index boundaries. I say this out because if I render a layer from a non-tiled image dataset, the corrupted areas appear as horizontal bands across the entire width of the image output, rather than rectangular areas (though my non-tiled dataset is a single-band floating-point DEM, rather than an rgb image). However, as before, the height and number of lines of each band is variable. Maybe it's just time to upgrade my OS (F7 is EOL after all).

[mapserver-users] Re: Corrupt image output
Hello again, Just to follow-up on this, this problem isn't limited to just image rendering. I also get odd results from raster queries in php mapscript - about half the time, I'll get appropriate rgb values, but as you can see in this example (http://img411.imageshack.us/my.php?image=corrupt2rj9.png), I don't always get the correct results. Often, I'll get zeros for all three values, or just one value - in that sample image, the location on the map indicated by the red dot should have something returned for all three red/green/blue fields. So perhaps this is a problem somewhere between mapscript and the gdal library?

[mapserver-users] Projection of shape objects in MapScript
Hello, I have what I hope is an easy question: when I extract shapes from query results in PHP MapScript, what projection would the shape be in? The map object usually has its own projection defined, as can the layer object...and then there's the data source itself (presumably the same as the layer object). So if I produce WKT from the shapeObj::toWkt() function, which reference system will the coordinates be in? I know I could figure this out on my own through experimentation, but I'm hoping someone already knows the answer. If it's in the documentation, then I've missed it...and I didn't turn anything up with a few web searches.

[mapserver-users] mapscript querybypoint on tiled raster layers?
Hello list,
I'm sure this one has come up before, but I can't seem to figure out
what I need to do. I have some tiled raster layers that I've got in a
mapfile that is being used for generating ka-map tiles. I'm trying to
query the values on these layer using the queryByPoint function in
php_mapscript. I have a generic identify function that returns results
for any of my vector layers, and for non-tiled raster layers - just not
for the tiled raster layers. Is it possible to query tiled raster
layers? If so, can someone spot what I'm doing wrong below?
The tiled-raster layers in the mapfile generally look like this:
LAYER
NAME Tiled Raster
GROUP Tiled Raster
STATUS ON
TYPE RASTER
TILEINDEX /data/index.shp
TILEITEM LOCATION
METADATA
imageformat AGG_JPEG
END
PROJECTION
init=epsg:4326
END
END
And here is the function in PHP:
public function Identify($oMap,$layer,$x,$y,$cellSize)
{
$oLayer = $oMap-getLayerByName($layer);
if (in_array($oLayer-type,
array(MS_LAYER_POINT,MS_LAYER_LINE,MS_LAYER_POLYGON)))
{
$oLayer-set(toleranceunits,$oMap-units);
$oLayer-set(tolerance,$cellSize*3);
}
else
{
$oLayer-set(tolerance,0);
}
$oLayer-set(template,dummy.html);
$oQPoint = ms_newPointObj();
$oQPoint-setXY($x,$y);
$aResults = array();
if (@$oLayer-queryByPoint($oQPoint,MS_MULTIPLE,$oLayer-tolerance)
== MS_SUCCESS)
{
$oLayer-open();
$nResults = $oLayer-getNumResults();
for ($i=0;$i$nResults;$i++)
{
$oResult = $oLayer-getResult($i);
$oShape = $oLayer-getShape($oResult-tileindex,
$oResult-shapeindex);
$aResults[] = array($oResult,$oShape);
}
}
return $aResults;
}

[mapserver-users] Re: mapscript querybypoint on tiled raster layers?
Ok...I figured out the problem pretty much right after I clicked send on
that last message. I had generated my tile index.shp with relative
paths for the LOCATION field (i.e., relative to the shp file). I just
regenerated it with absolute path names, and it the query function works
fine.
So would this be a known bug of any sort, or is it just bad practice to
use relative filenames with MapServer?

Mike
