[mapserver-users] FES 1.1.0 in mapfile
Hi all, I am trying to use Filter Encoding in mapfile. Here http://mapserver.org/ogc/filter_encoding.html#filter-encoding is an example given, which goes like this: wfs_version 1.0.0 wfs_filter PropertyIsGreaterThanPropertyNamePOPULATION/PropertyName Literal1000/Literal/PropertyIsGreaterThan with remark The filter given as a value of the wfs_filter metadata should not contain Filter start and end tags. However, I would like to use something like wfs_version 1.1.0 wfs_filter 'ogc:Filter xmlns:ogc=http://www.opengis.net/ogc;ogc:PropertyIsEqualToogc:PropertyNameSLT/ogc:PropertyNameogc:Literal1A/ogc:Literal/ogc:PropertyIsEqualTo/ogc:Filter' Two questions arise: - Is wfs(fes) version 1.1.0 supported? - How am I expected to specify the namespaces, if start and end Filter tags should be omitted? FYI, direct request http://localhost//cgi-bin/ows?REQUEST=GetFeatureVERSION=1.1.0SERVICE=WFSTYPENAME=typFILTER=ogc:Filter xmlns:ogc=http://www.opengis.net/ogc;ogc:PropertyIsEqualToogc:PropertyNameSLT/ogc:PropertyNameogc:Literal1A/ogc:Literal/ogc:PropertyIsEqualTo/ogc:Filter works just nice, now I am trying to automatically generate the mapfile by dedicated python proxy using mapscript; the filter itself is generated by OpenLayers in the javascript web client.

Re: [mapserver-users] FES 1.1.0 in mapfile
Hi, Some quick questions: Are you planning to cascade some other, remote WFS service through your Mapserver? And that remote service is using WFS 1.1.0? Is the remote service something you know or could it be just any WFS service, made with Mapserver, Geoserver, TinyOWS, deegree, ESRI product, Oracle etc. ? -Jukka Rahkonen- Michal Šrédl wrote: Hi all, I am trying to use Filter Encoding in mapfile.

Hi Jukka, 2011/11/11 Rahkonen Jukka jukka.rahko...@mmmtike.fi: Hi, Some quick questions: Are you planning to cascade some other, remote WFS service through your Mapserver? Yes. And that remote service is using WFS 1.1.0? Yes. Is the remote service something you know or could it be just any WFS service, made with Mapserver, Geoserver, TinyOWS, deegree, ESRI product, Oracle etc. ? It can be any WFS service. For development, I use my Mapserver twice, first as a remote WFS server and then to back my python proxy. For deployment, the remote wfs service is meant to be any wfs 1.1.0 service.

[mapserver-users] Raster image performance
Does anyone have any experience of how to get the best performance out of raster formats. We have an application which needs to be able to display a number of zoom levels and once we get out to whole earth or continent level the performance is poor. Our assumption is that it is the shrinking of the images which where is the time if being used up. The raster files are tifs with external world files, adding overviews helps a little. The zoom levels and output resolution can be fixed so if the overviews match exactly the required image size that look like it would work but we cannot see how to do this. So any advice on what are the most efficient file formats to open and the most efficient output format. The application is written in php mapscript which runs as a service and not via a browser.

Re: [mapserver-users] Raster image performance
Ian, I am guessing you actually have many files, not just one big one. Is that right? As you zoom out opening many files to accumulate the full image is expensive. Up to some scale it is practical to merge things into one big mosaic tiff with overviews. At some point that can be impractically large. The usual practice to avoid opening too many files with tileindexed layers is to have two LAYERs in your map file. One for the fuller resolution data, and then another at greatly reduced resolution and then to generate a reduced resolution mosaic for the reduced resolution layer. Use the MIN/MAX SCALE control keyword in the LAYER to control which is used.

Re: [mapserver-users] GAP problem on MapServer 6.0.1
Dear Stephen, We've checked that vertices of line are not coincide. Please check the attached MapInfo file. It's the problematic part taken out from the original map. On Fri, Nov 11, 2011 at 9:47 AM, Stephen Woodbridge wood...@swoodbridge.com wrote: Jackey, I have seen this problem before and I think it is related to the fact that you might have coincident points in your line. For example if the first and second point in the linestring have the same value. This causes problems when we try to compute the heading for that segment. If you want me to check on that for you then send me a zip of the shapefile with just the bad line in it. If this is the case, we should probably write a bug ticket for this case. -Steve On 11/10/2011 8:03 PM, Jackey Cheung wrote: Thanks for your comment, Havard Tveite. As you suspected, the strange position (and also redundant) of arrows is problem in figure 1. Since there is only one line there, we expect only one set of (around 2~3) arrows were rendered. We can't figure out why there are redundant arrows rendered at strange positions. The expected outcome is only 2~3 arrows shall be rendered right around the center of the line.

Your arrows seem to point in the direction of the lines. The topmost arrow in figure 1 is placed at a strange position - is that the problem? Some comments: The result shown in image 2 is expected. The arrow symbols are in this case placed at the start points of the lines according to the centre point of the symbol's bounding rectangle (except 0,0 is always taken as the upper left corner of the bounding rectangle). When using a negative GAP, the direction of the symbol is the direction of the line at the (end)point. In version 6.2, ANCHORPOINT is introduced to make it possible to specify a different anchor point for the symbol (http://mapserver.org/trunk/mapfile/symbol.html). The centre point of the bounding box of your arrow_right symbol will be at (17.5,7) in the symbol's coordinate system, so the arrows will be placed somewhat shifted to the right (in the direction of the arrow). In 6.0, if you want the ends of the arrows to be aligned with the start of the lines (when using geomtransform start), you could use the following symbol: SYMBOL NAME arrow_right_shift TYPE VECTOR POINTS 30 6 52 6 50 0 60 7 # why 7.5? 50 14 52 8 30 8 30 6 END FILLED TRUE END In 6.2, you will be able to specify this using ANCHORPOINT 1 0.5 Håvard On 11/10/2011 06:35 AM, Jackey Cheung wrote: Hi all, We are trying to render line direction on 6.0.1.

Then we've tried to change GEOMTRANSFORM to start or end, then rings seem OK, but all arrows at intersections got crossed, as 2.PNG. We've also tried to use OFFSET and GAP with positive and negative combinations, but none can solve the problem. Can anyone shed some light for us?
