I'm not familiar with Scientific Linux so I don't know. If you do have ECW support it would be handled by GDAL, which you have as evidenced by INPUT=GDAL, so you need to determine if GDAL has ECW support, which is pretty easy. In the shell: gdalinfo --formats or better yet gdalinfo --formats | grep -i ecw will list the formats tha GDAL can handle in your setup. If ECW isn't in the list then you need to install or build supporting libraries, but I have no idea how you do that in Scientific Linux.

Use something like jQuery (my Js weapon of choice) to construct an ajax query. A JSONP query requires just one additional letter "P". 2. Use a proxy. Remember, a few days ago I was asking about how to specify different classes in the browser address bar (in the URI) and use that to specify which classes are rendered by MapServer? I solved that by using a proxy... just a couple of lines of Perl, and that was solved. A bonus hint -- if your data are in Pg, don't even bother with getFeatureInfo. Just query the db directly and return the data as JSON (or, JSONP, in this case). -- Puneet Kishor___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

[mapserver-users] MapServer & feature datasets
Hi, I am trying to establish a connection to a Spatial Database Engine (SDE) and I am using the following parameters: CONNECTIONTYPE PLUGIN PLUGIN "C:/ms4w/Apache/specialplugins/msplugin_sde_92.dll" All my information (shape files) is inside different feature datasets in my Database. However, if I keep my shape files inside feature datasets, I can access the WMS, but I cannot do the operation GetFeatureInfo in the map as my WFS does not work. However, when I move the shape file out of the feature dataset, I can do the operation GetFeatureInfo in the map and I my WFS is perfect. I am using ArcSDE 9.2 and my MapServer version is 5.6.6. Did anyone have this problem? There is any solution for WMS and WFS that includes shape files inside feature datasets in a Spatial Database Engine (SDE)? Many thanks in advance.

[mapserver-users] Re: CLUSTER and GetFeatureInfo
Hi Tamas, I played around a little bit with a clustered Layer that has "CLUSTER_GET_ALL_SHAPES=ON" and "ITEMS=id" as processing options. I'm using trunk of course, and i noticed one thing: I have a cluster that is made up of 2 features. When i make a feature info request to the cluster, it returns GML. The GML contains two items: 394 2 As you can see, the first feature is returned correctly. However the second feature doesn't have its original attributes, but instead has the cluster's attributes. When i test this in different scenarios, i always end up with one missing feature - the one that has "become" the cluster (not sure about the implementation details). Have you maybe experienced the same behavior or do you have an idea why this is happening. Maybe i'm just missing something in the Mapfile. I could deliver some SQL + Mapfile to reproduce this, if needed.

Re: [mapserver-users] How ro get transparent image on 6.0.1
Either your asp page is selecting the wrong (i.e. a non-transparent) imagetype, or you have a layer that is drawn ontop of the transparent background, thus making the final image non transparent. The outputformat you have shown is correct and produces trasnparent images. -- thomas On Thu, Nov 3, 2011 at 14:46, Janeks Kamerovskis wrote: > Hi, > > I recently moved to 6.0.1, but stumped to getting transparent image. > > I used following syntaxis in my map file: > > IMAGECOLOR 255 255 255 > > OUTPUTFORMAT > NAME "png" > DRIVER AGG/PNG > MIMETYPE "image/png" > IMAGEMODE RGBA > EXTENSION "png" > FORMATOPTION "GAMMA=0.75" > TRANSPARENT ON > END > > IMAGETYPE png > > But my request is still getting nontransparent image: > http://10.162.129.14/MapApp/wms_rs.asp?LAYERS=rs&TRANSPARENT=true&FORMAT=image%2Fpng&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&STYLES=&SRS=EPSG%3A25884&BBOX=166509.5,6040766.7857144,908910.5,6571053.2142856&WIDTH=1050&HEIGHT=750 > > What could be wrong? > > brgds & thanks in advance > Janeks > ___ > mapserver-users mailing list > mapserver-users@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/mapserver-users > ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Re: [mapserver-users] arrow head doesn't draw at the end
An update regarding RFC45: Thomas B. has now implemented SYMBOL ANCHORPOINT, which can be used to specify the anchor point of a symbol. With this functionality, it is very easy to implement symbols that is to be placed and rotated according to something else than their centre point. I have tested mapserver trunk, and it works like a charm. It is also documented in the trunk documentation. http://www.mapserver.org/trunk/mapfile/symbol.html So there is reason to look forward to 6.2!

Perhaps it is clear as crystal to the rest of the world, but I can't fathom anything there applicable to me. I am facing four problems -- 1. As I mentioned below, per the docs, I am supposed to be able to declare "ANGLE AUTO" in my STYLE definition. That simply does not work for me. I *have* to declare the angle the same as the angle of the stem of the arrow "ANGLE [az]" in order to get arrow heads headed in the same direction as the arrow stems. 2. From the docs on GEOMTRANSFORM, "end: produces the last point of the geometry. When used with ANGLE AUTO, it can for instance be used to render an arrowhead." Well, no... it is *not* producing the *last point of the geometry* as I understand it. Instead, it is producing the middle point of the geometry. And it sure as as I can see is not working with ANGLE AUTO (see #1 above). 3. I have tried several variations on my arrow head to try shift its center, but I am failing to translate the information in the above document to be able to do it correctly. 4. Perhaps most important: the length of the arrow is varying based on [rate]. In other words, I want only the stem to be shorter or longer, but the arrow head to be the same size, and to be at the "end" of the stem always. In fact, there are instances in which [rate] could be equal to zero. In those instances I don't want any arrow to be drawn at all. *** In other words, I want an arrow stem to be as long as the varying [rate], and if the stem has a length greater than zero then and only then do I want an arrow head at the end of the stem pointing in the same direction as the stem. *** I even tried using a truetype font symbol, but I get no image at all but no error as well. I even tried using a SYMBOL of TYPE pixmap pointing to an image of an arrow. I realize that if I could make that work, it would still be unsatisfactory because as MapServer would scale my arrow image, it would make the attached arrow head also larger, and that would look ugly. In any case, I couldn't get that to work as well... no image at all, but no error as well. Could be my compilation of MapServer was buggy, but I didn't see any compilation time errors, and other than the above oddities, it works quite well. $./mapserv -v MapServer version 6.0.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=ICONV SUPPORTS=WMS_SERVER SUPPORTS=WMS_CLIENT SUPPORTS=GEOS INPUT=POSTGIS INPUT=GDAL INPUT=SHAPEFILE I would love to know if my *** objective *** above can be accomplished with MapServer. If not, I would look at other workaround. I am currently rendering arrows using OpenLayers vector layer... it works quite well, but is slow... MapServer is much faster, and could be cached, hence my desire to use MapServer. Thanks.

AW: [mapserver-users] Re: Reaspect?
The WMS standard was written this way to support display devices with non-square pixels. So it seems to me that you don't want to use a WMS service. You should really consider using MapServer with "mode=map". This mode is more appropriate for custom web applications while the WMS standard is used to increase interoperability. > That's pretty much what we've decided to do, although the > resulting image is > no longer square.
