You need to specify the central meridian (i.e. the UTM zone) each is in. You might find it easier to look up the EPSG codes for each projection and just use the codes. They're more cryptic but less error-prone. You can find them at http://mapserver.gis.umn.edu/doc/proj.html The NAD27 UTM zones are five-digit numbers of the form "267zz" where zz is the two-digit (pad with a leading zero) zone number.

                                   How it is happening? I have changed the name of data section in the .map file to include new data.Everything else remains same.How to get that?

Try setting it to the boundingbox of the shapes you have. If you don't know this, (i think) you can obtain the bounding box coordinates using the ogrinfo utility that comes with gdal. Eventually change the projection and units also. Regards, Vincent Schut.

Dan gave me a nice example, but, unfortunately, I can't manage to make it work. I am working with MapScript 3.6.2 and I wonder if the problem is that MS 3.6.2 doesn't know the "annotation" type layers ? ? ?. Here are my settings when I hit the phpinfo page : MapScript Version ($Revision: 1.104.2.4 $ $Date: 2002/07/08 20:04:58 $) MapServer version 3.6.2 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS_SERVER INPUT=TIFF INPUT=EPPL7 INPUT=JPEG INPUT=SHAPEFILE I am using .phtml and .php pages which are working pretty similar to the ones of the "gmap75" demo. Here is the answer that Dan gave me when I first asked the question : <<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>> Blaise, Yes it can be done...here is some simple example code in php/mapscript and the associated map file layer. Dan $map = ms_newMapObj($mapPath.$mapFile); $image=$map->draw(); $testlayer = $map->getLayerByName("labels"); $testpt = ms_newPointObj(); $testpt->setXY( 200, 200 ); $testpt->draw($map, $testlayer, $image, 'labels', 'Hello World'); $testpt2 = ms_newPointObj(); $testpt2->setXY( 300, 200 ); $testpt2->draw($map, $testlayer, $image, 'labels2', 'GoodBye World'); LAYER NAME labels STATUS on TRANSFORM false TYPE annotation CLASS NAME labels LABEL type truetype font verdana-bold bold size 8 antialias true backgroundshadowcolor 51 51 51 backgroundshadowsize 2 2 color 51 51 51 position UR END END CLASS NAME labels2 LABEL type truetype font coopperplate-gothic-bold size 8 antialias true backgroundshadowcolor 51 51 51 backgroundshadowsize 2 2 color 51 51 51 position UR END END END <<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>>>>> I am a bit confused about where to put this piece of php code. As, in my php page, the only $map->draw() command is in the GMapDrawMap function, I put it there. Here is my map file related to the label layer : <<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>> ################################## layer labels ############# LAYER NAME labels STATUS ON TRANSFORM false TYPE annotation CLASS NAME labels LABEL TYPE truetype FONT fritqat SIZE 12 COLOR 0 0 255 POSITION UR END END END # Layer <<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>> and here is the beginning of the GMapDrawMap function where I inserted Dan's code: <<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>> /************************************************************************/ /* function GMapDrawMap() */ /* */ /* Funcion to draw the contains of the map. */ /************************************************************************/ function GMapDrawMap() { GLOBAL $gpoMap, $gbShowQueryResults; GLOBAL $gbIsHtmlMode; GLOBAL $gszCommand, $gszZoomBoxExt; GLOBAL $gAppletImgFmt, $gImagesFmt; GLOBAL $TLayer; // if ($gbShowQueryResults) // $img = $gpoMap->drawQuery(); // else // $img = $gpoMap->draw(); //----------------------------------- test label--------- $map=ms_newMapObj("label_2.map"); $img=$map->draw(); $testlayer=$map->getLayerByName("labels"); $testpt=ms_newPointObj(); $testpt->setXY(100,100); $testpt->draw($map,$testlayer,$img, 'labels', 'Hello World'); //------------------------------- end test label--------- $url = $img->saveWebImage($gAppletImgFmt, 0, 0, -1); echo "\n".$gszZoomBoxExt."\n"; printf("", $gpoMap->extent->minx); printf("", $gpoMap->extent->miny); printf("", $gpoMap->extent->maxx); printf("", $gpoMap->extent->maxy); etc,etc,etc.......... <<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>> As I disabled the $gpoMap variable, I can't zoom in, out,etc anymore, but that's ok until I get my labels on the map. But unfortunately, the label 'Hello World' doesn't show. In the "$testpt->setXY(100,100);" line, I tried to put the X,Y of the middle of my mapextent, tried to comment the " TRANSFORM false" line in my map file, but this doesn't work neither. I am wondering what is wrong, and does the version 3.6.2 of MapServer/MapScript support the annotation type for a layer ? Thanks a lot for your help, and many thanks for the MapServer team who are doing a great job. I am very satisfied with this software.

You need to specify the central meridian (i.e. the UTM zone) each is in. You might find it easier to look up the EPSG codes for each projection and just use the codes. They're more cryptic but less error-prone. You can find them at http://mapserver.gis.umn.edu/doc/proj.html The NAD27 UTM zones are five-digit numbers of the form "267zz" where zz is the two-digit (pad with a leading zero) zone number. So to define a UTM Zone 9, NAD27 projection you can say: PROJECTION "init=epsg:26709" END - Ed Ed McNierney President and Chief Mapmaker TopoZone.com / Maps a la carte, Inc. 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 ed@topozone.com (978) 251-4242 -----Original Message----- From: John Norton [mailto:jnorton@fs.fed.us] Sent: Wednesday, April 30, 2003 4:49 PM To: mapserver-users@lists.gis.umn.edu Subject: [Mapserver-users] Projection on the Fly Problems I Have a map file with two layers...

Are you on linux? If you know the size of your images, you can write a shell script to use 'gdal_translate -srcwin xoff yoff xsize ysize in.tif out.tif', looping automatically over your raster image using the appropriate window. Even if you don't know the imagesize, you could get that by parsing the gdalinfo output in your script, but that might be a bit more trickier. Another option: If your raster can be saved as a normal tif (or otherwise non-geographic image format), you could use the convert program (coming with imagemagick), it has some automatic tile command, check the docs, I don't know it by heart. You can then after that add geo information with gdal or just by adding world files (which you could generate with a script again :-)). Third option: make a map file with your raster in a layer and write a simple php/mapscript program that loops over the extent of your raster, changes the extent to the tile you want to have, have mapserver draw your image (if you have a recent version of mapserver and gdal, mapserver will even be able to generate geotiff image files (or any image format gdal can write) for you if you set the outputformat section accordingly!), and save it.

Message-ID: Thanks, Vincent. I should have delved deeper into MapServer source on my own, but after listening to your advice and looking at http://ming.sourceforge.net/docs/index.php?mode=php, things seem clear. At this point I guess it boils down to whether or not our users should be forced to have a plug-in to view the flash animation. GIF's self-containment sure is compelling, but that comes at a cost of limited features. Same argument goes for the rosa applet download, too. But there's no harm in checking it out!

Charlton, You could use the same library Mapserver is using to produce it's swf's: ming. It's free, and you can use actionscript. It has a php component too. You can simply program quite complex swf's with that. See the website for more details, api, etc.: http://ming.sourceforge.net/ , and the ming docs at php.net. However, especially when using the php extension (it is a c library originally) be carefull and play around a bit with different versions, cause not every version of ming works with every version of php. And it is still in development, so not everything is working properly. My own experience: though you might want to use ming-cvs (lots of errors fixed and some better functionality) I could not get it to work with php. The version I currently have is ming 0.2a (the tar.gz from the website) which works in combination with the ming extension that comes bundled with php 4.3.1. If you want to use a newer ming, you might have to use it as a c library. Which is very well possible, though, cause you can produce a static swf that dynamically loads a mapserver produced swf on request, like Ryan Grant wrote. However, when using this combination be carefull not to mix ming02.a and ming-cvs (you will need them both I think, cause mapserver depends on 0.2a?). However, with only 0.2a it's quite possible to produce nice mapserver interfaces. You can look at an (very simple) example at http://www.sarvision.nl/mawas/mapserver/ms-mawas.php . It has nothing to do with image sequences, but shows you a bit of the possibilities of ming and building interfaces and integration/communication with mapserver.

The shapefile is produced by arcview, and in av I can't find any weird things. I loaded it into postgres/postgis0.7.5, simplified it using a strk's Douglas Peuker implementation for postgis (tolerance 0.1025 DD), wrote this to shape again, and suddenly some more labels appear. But still not all. I hope that somebody with more knowledge on shapefile/mapserver interaction thinks this interesting enough to have a look at it :-) I will be in Brasil next week and probably won't read email and surely won't be able to test things, so I will put the (simplified) shapefile on the internet where you can download it for testing purposes.

I manually set the extent void setextent(double minx, double miny, double maxx, double maxy) and everything is right now.

You draw the map . . . $img = $map->draw(); $url = $img->saveWebImage(MS_PNG, $map->transparent, $map->interlace, 50); . . . at the very beginning of your .php -- before you run down the legend checkboxes where you turn layers on and off. Shouldn't this be toward the end, say, near the . . . include($path_to_legend . "legend.php"); . . . line after you've set the layers in the $map?

Message-ID: Actually there is no pre-requisite for tiles other than that they be polygons. Behind the scenes the decision to process a tile or not is based on the bounding box of that feature (I believe) so there are certain inefficiencies that can occur with irregularly shaped tiles that don't truly intersect the area of interest. I and others have use things like counties or landsat footprints with success in the past. Steve Stephen Lime Data & Applications Manager Minnesota DNR 500 Lafayette Road St. Paul, MN 55155 651-297-2937 >>> "Ed McNierney" 04/30/03 07:26PM >>> Bob - Your TILEINDEX should be rectangles. The intent of a TILEINDEX is to allow MapServer to quickly determine whether to examine an input file to see if it has any visible features on the current map request. Rectangular tiles can be very quickly examined to see if they intersect the map viewframe. If so, the source is opened and any files that REALLY intersect the view are drawn. Supporting non-rectangular tiles would be more complex and somewhat slower, and would probably be of rather little benefit in most applications. A good combination of rectangular tile indexes and spatial indexing will produce very good performance. - Ed Ed McNierney President and Chief Mapmaker TopoZone.com / Maps a la carte, Inc. 73 Princeton Street, Suite 305 North Chelmsford, MA 01863 Phone: (978) 251-4242 Fax: (978) 251-1396 ed@topozone.com -----Original Message----- From: Bruce, Bob (CON) [mailto:BBruce@gov.mb.ca] Sent: Wednesday, April 30, 2003 7:54 PM To: 'Mapserver Mailing List' Subject: [Mapserver-users] Non-Rectangular Tiles in TILEINDEX ? I have been experimenting with TILEINDEXs in order to evaluate their functionality for my applications. I have successfully displayed a TILEINDEX of 20 orthophotos in my browser. Next I wanted to try displaying a set of project mapping areas and built an index map of polygons of these areas. I included this index map as a TILEINDEX in my map file and do not get anything displayed, instead I get a blank display. This leads me to wonder if this is because my tile polygons are non-rectangular. Does the Map Server require tiles to be rectangular or can it work with irregularly shaped tiles? I have successfully displayed my dataset that I'm using as a TILEINDEX as a line file, so I know that the server will work with this file. For your reference, I have included the definition of this layer: LAYER # DLS Polys NAME "DLSPolys" TILEINDEX "TilesWWinnipeg_CARIS/TilesWWinnipeg" TILEITEM "MAPKEY" STATUS DEFAULT TYPE POLYGON CLASSITEM "MAPKEY" CLASS # Whole DLS Parcel STATUS ON NAME "WHOLE DLSPOLY" COLOR 255 202 149 OUTLINECOLOR 0 0 0 END # end of Whole DLS Parcel class object END # end of layer object thanks, Bob Bruce ************************************************************************ ********************************** ** Bob Bruce, P.Eng.
