Re: [mapserver-users] How do I make a shapefile polygon thicker within UMN Mapserver
The good news is, if I recall correctly, starting from MapServer 5.0, the WIDTH parameter affects the width of the outline of polygon layers.

Re: [mapserver-users] tiling (WMS-C)
Chris, That makes more sense. So MapBuilder is magically noticing the WMS-C in your URL and converting its requests to a tiled mode. Unfortunately, Mapserver does not understand the WMS-C keyword and is croaking, even though there is no functional difference (from a WMS PoV) to serving a WMS-C request and a WMS request. A quick and dirty fix would be to write a small PHP script to sit in front of mapserver, convert the WMS-C to a WMS and then pass the request onwards. Alternately (and more elegantly), perhaps there is some way to trick mapbuilder into the tiled mode without the WMS-C keyword in the URL? Check your Mapbuilder docs.

[mapserver-users] Using PHPMapscript from php script called in console
I am having a strange occurrence. I have a php script that uses PHP mapscript to manipulate some maps. I have no problem with it if I call the script from my web browser, however, when I call it via command line PHP, i.e., "php scriptname.php", it fails when I try to do anything with the map object. I have done a phpinfo() from my script and verified that mapscript is in fact loaded when php is invoked from the command line. It looks as thought the command that I am using to instantiate the map object instance is failing. To create the object, I use: $this->map = ms_newMapObj($map_path.$map_file); To verify this creation I use: print_r((array)$this->map ); Which yields, Array( [0] => ) when I call it from the command line, and a fill set of object properties from the browser, as in: Array ( [_handle_] => Resource id #41 [numlayers] => 8 [name] => PrecipMap [status] => 1 [debug] => 1 [width] => 720 [height] => 500 [maxsize] => 2048 [transparent] => - [interlace] => - [imagetype] => AGG [imagequality] => - [extent] => ms_rect_obj Object ( [_handle_] => Resource id #42 [minx] => -79.322914123535 ... (etc. etc.) The only difference that I can think of is that the php-cgi.exe is getting used by the browser, while php.exe is used at the command line. I tried executing the script with the cgi version, but to no avail, same behaviour, script dies without any word whenever I try to call a mapObj method. System: Windows XP PHP 5.2.5 Mapscript - PHP MapScript Version => ($Revision: 7251 $ $Date: 2008-01-08 12:04:53 -0500 (Tue, 08 Jan 2008) $) Any guidance would be appreciated, r.b. Robert W.

I don't think you can change the thickness of a polygon's outline. You may have to draw the layer twice, once as TYPE POLYGON, then again ad TYPE LINE. MapServer actually allows you to draw polygon features as lines. With line layers you can change the thickness of features.

RE: [mapserver-users] How do I make a shapefile polygon thicker withinUMN Mapserver
John, One very common approach is to use a symbol for your line style, and then adjust the size. Viz: CLASS NAME "proj_seggroups" SYMBOL 'circle' SIZE 3 COLOR -1 -1 -1 BACKGROUNDCOLOR 0 0 0 OUTLINECOLOR 0 0 0 END And then of course, you need to have the symbol 'circle' defined. This is done in the top portion of the mapfile (perhaps the order is not important, but in all the examples I have seen it is there): SYMBOL NAME 'circle' TYPE ELLIPSE POINTS 1 1 END FILLED TRUE END Robert W.

RE: [mapserver-users] Simple polygon imagemap creation
Charles, I have done just this thing, and it is quite easy. Coincidentally, I have just completed a set of these for Virginia's Water Resources division. I am doing this for a drought monitoring application, creating static, clickable image maps that then connect to a small data retrieval application. Here is an example (coincidentally on the Virginia - North Carolina border): http://www.deq.virginia.gov/watersupplyplanning/drought/southside/curren t.html I based my version on a good example by Steve Lime: http://maps.dnr.state.mn.us/cgi-bin/mapserv48?map=/usr/local/www/docs_ma ps/eco/rsg/search/search_example.map&qlayer=county&mode=nquery&searchmap =true Anyhow, the basics are: the layer that defines the image map needs to have header, footer, and body templates set. The header just has to open the tag, and the footer closes it , and the bodytemplate has to have the stuff that tells mapserver where to put the shapes. Entities in brackets [] in these files are variables from your layer. In my example, I am using a PostGIS layer, but the same holds true for shapefiles. The only other contingency is that you should have a querymap defined (at least in the way that I am calling it, one needs this), and that is simple: QUERYMAP STATUS ON STYLE NORMAL END Please get in touch if I can help at all.

Hi Yatendra, layer.close(); , here layer is the base layer. The code that I have provided is used to colour features in the layer (You can change the entire layer color also). The layer has many features, which can be retrieved using shapeObj shape = layer.getFeature(shapeInd, -1); "shapeInd" is the index of the shape. This is the shape that i use to add into the temporary layer created oTempLayer.addFeature(shape); So, once I add the shape that I want to color to the temporary layer, I close the base layer using layer.close(); I hope this helps.

Re: [mapserver-users] Coverting lat/long to pixel
Thanks Brian.
I actually need to find the intersection of a rectangle and circle. As you
must be aware that a circle in mapserver terminology is a shapeobject drawn
using the upper left and bottom right co-ordinates of a rectangle.
In the above case I get the intersection of two rectangles, but as the
circle lies inside the rectangle, i am not able to find whether my first
rectangle intersects with the bottom corner of the rectangle(that contains
the circle), which is not part of the circle.
Any solution in this case would be of great help.
Thanks,
Sucharita

In ka-Map the layers without the attribute GROUP, are all merged in the base layer; you can check this in the Foss4g 2006 presentation (page 12). Let me know.

Re: [mapserver-users] Layer always turn on (not possible to activate/deactivate)
Hi Luca, Thanks for your help. To set no GROUP is not working.. Maybe this is the solution using mapserver only, but with ka-map if I don't set group to this layer then the other layers disappear from the legend and in general everything stops work well. Is there other way? thanks anyway 2008/5/7 Luca Casagrande <[EMAIL PROTECTED]>: > > Il giorno 07/mag/08, alle ore 19:34, Emilio Ponce ha scritto: > > Hi everyone, here's a newbie question: > > I'm using mapserver with ka-map and I have different layers in a unique > mapfile.
