[mapserver-users] Refresh changes on map
Hi, I'm using mapserver with a layer stored on a data base with a lot of points, which I updated with other application. I would like that Mapserver draw this points depending on an atribute visible. Can Mapserver update the layer on the next wms request with the points updated? How I should set up my mapfile to do this?

[mapserver-users] WMS BBOX tolerance out of this world?
Hi, all. I'm hoping that someone knows this answer off the top of their head so I won't have to sort through mountains of OGC specs. That's the lazy developer in me. Let's say we're dealing w/ epsg 4326. We as humans (some mostly human) know that this generally means -180,-90,180,90. Or perhaps sometimes 0,-90,360,90. My question is, does the WMS server need to support queries outside of these bounds? E.g. for a dataset advertised as 4326 w/ bounds -180,-90,180,90, if the user requests -198,-99,198,99, should the user get the 'data' image surrounded by white space or get an error that says 'sorry, that was something I don't understand'? A GetCaps can advertise the BBOX for the site and each layer, but I'm still asking about these exceptional cases. I dug around and found that both ESRI and MapServer WMS servers support these queries just fine. But are they being nice, or does the WMS spec say that these are valid queries and that the servers should support them? Many TIA, Charlton Examples of ESRI MapServer queries.

RE: [mapserver-users] Refresh changes on map
Eduardo, Yes, this is possible. Every request to MapServer is made against the latest version of your data. To draw only points with a value of 'yes' in the column named 'visible': - add a layer to your map file that connects to your data source. - add a class to the layer - add a style to your layer that defines how the points will be symbolized - Now, test the map file at this point to see if your data works correctly. You can do this by using the shp2img utility that comes with MapServer or even easier, make a URL request to MapServer using mode=map. - once the layer works, add an filter to your layer. The syntax may vary based on the database that you are using, but it should be something like FILTER visible = 'yes'. I think that the simplest strategy for you is to: - get the layer working as a simple CGI MapServer call. - then apply your expression to limit the points to only the ones that you want - finally, modify your map file to server the layer as a WMS David. -Original Message- From: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] On Behalf Of Eduardo de la Montaña Sent: Tuesday, February 09, 2010 4:00 AM To: mapserver-users@lists.osgeo.org Subject: [mapserver-users] Refresh changes on map Hi, I'm using mapserver with a layer stored on a data base with a lot of points, which I updated with other application.

[mapserver-users] RE: WMS BBOX tolerance out of this world?
My question is, does the WMS server need to support queries outside of these bounds? E.g. for a dataset advertised as 4326 w/ bounds -180,- According to the 1.1.1 spec . . . If a request contains a Bounding Box whose area does not overlap at all with the BoundingBox advertised in the Capabilities XML for the requested geodata object, the server should return empty content (e.g., a blank map, empty coverage file, null feature set) for that element. Any elements that are partly or entirely contained in the Bounding Box should be returned in the appropriate format. If the Bounding Box values are not defined for the given SRS (e.g., latitudes greater than 90 degrees in EPSG:4326), the server should return empty content for areas outside the valid range of the SRS. Well, it sounds pretty clear then. Return the data for the area that is defined. Right? ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] WMS BBOX tolerance out of this world?
Charlton Galvarino wrote: My question is, does the WMS server need to support queries outside of these bounds? E.g. for a dataset advertised as 4326 w/ bounds -180,-90,180,90, if the user requests -198,-99,198,99, should the user get the 'data' image surrounded by white space or get an error that says 'sorry, that was something I don't understand'? A GetCaps can advertise the BBOX for the site and each layer, but I'm still asking about these exceptional cases. I dug around and found that both ESRI and MapServer WMS servers support these queries just fine. But are they being nice, or does the WMS spec say that these are valid queries and that the servers should support them? My interpretation of the spec is that it is okay to return white space and those cases. Here is what WMS 1.1.1 section 6.5.6 says about this: If a request contains a Bounding Box whose area does not overlap at all with the BoundingBox advertised in the Capabilities XML for the requested geodata object, the server should return empty content (e.g., a blank map, empty coverage file, null feature set) for that element. Any elements that are partly or entirely contained in the Bounding Box should be returned in the appropriate format. Later in the text, they open the door to an (optional) exception to the above rule for maps crossing the date line (+/- 180 degrees longitude), in which case a server could choose to support requests such as lon=120,250 to cover the Pacific Ocean for instance. However I don't think this changes the answer to your question, i.e. it is okay for a client to request maps whose bbox does not fit strictly inside the advertized layer bounds, and in this case the client should expect some white space around the data.

[mapserver-users] Pixmap problem
Hi, I'm using pixmap (a PNG image) for my layer of points on Mapserver. It works perfectly, but when the point is near of the edge of the tile, the symbol appeared cutted, only part of the symbol is visible. How can I solve this problem? Any suggestion is welcome, Thanks in advance attachment: emontana.vcf___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
RE: [mapserver-users] Pixmap problem
For point symbols I don't believe you can stop the cropping of the marker. To do so you'd need to probably switch to an annotation layer in which the markers are considered part of a label. Then you can set PARTIALS FALSE in the label object. The downside here is that the label processing will remove overlapping markers which may not be what you want. You can try setting LABELCACHE OFF (layer object) or even FORCE TRUE (label object) to get around that. Here's a sample layer definition (not tested): LAYER NAME 'markers' DATA 'some point shapefile' STATUS DEFAULT TYPE ANNOTATION CLASS STYLE SYMBOL 'marker.png' END LABEL PARIALS FALSE FORCE TRUE END TEXT ' ' # I think you have to draw some text for this to work END END Something to try anyway...

I don't want to see this die. Perhaps we could take thread and either rework RFC 6 (http://mapserver.org/development/rfc/ms-rfc-6.html) which has to do with color ramping or create a new one to supplant it. Any takers?

To build on what Steve is saying it might help to think of features in mapserver as requiring two separate components: 1) the algorithm 2) the presentation Obviously you can not present something that you do not have. the algorithm is how you generate stuff. Once we have stuff we need to present it via the multitude of rendering modules and interfaces, like the CGI interface or template interface, etc and rendered as text, json, xml, etc. I think adding a STATS object might be a good way to add pluggable algorithms and filters into the layer. A year plus ago, I did some research into thematic cartography and the math and statistics involved in that. Here are some of the data classification methods we might want to support: 1) equal intervals 2) quantiles (quartiles are n=4 quantiles) 3) mean-standard deviation 4) maximum breaks 5) natural breaks 6) optimal You can probably find more on these on wikipedia if you want the math behind them. In addition to the above for choropleths we might want to consider bivariant or multivariant analysis. And there is also a need to apply filters to the data like: 1) eliminate outliers 2) numerous smoothing algorithms that might be appropriate - triangularization - inverse distance - kriging - various interpolation routines that solve various issues with the data 3) probably others You might look on Amazon used books for some reference material on thematic mapping. I got the following: Introduction to Thematic Cartography, by Judith Tyner Thematic Cartography and Visualization, by Terry Slocum Thematic Cartography and Geographic Visualization, by Slocum, McMaster, Kessler and Howard These are all excellent and there are a lot of others. I think the point here is that there is a lot of research that has gone into this field and if we want to build tools that will allow mapserver to work effectively in this area, and I DO think we should do this, then we need to understand the scope of what needs to be done even if it is not all done at once and we need to build a pluggable interface that allows us to easily add stats analysis and apply statistical filters as the need arises. I think for the most part what Steve L has described will meet (I guessing) 80-90% of the requirements that might reasonably thrown at us and the others we can most likely say are too specialized or out of scope. I will also note that for the most part it can be argued that mapserver should NOT do the analysis, that that is the realm of other tools, but given that the analysis has been preformed that mapserver needs to support rendering it. Some of the analysis mentioned above it non-trivial to do on the fly. It is not clear to me where we draw a line in the sand and justify yes this in mapserver, no, that is not in mapserver. Ok, sorry this probably way more than any of you want to know :) -Steve W Lime, Steve D (DNR) wrote: You're always mixing things up aren't you... I don't think you need a special mode. This strikes me as just another special form of template output based on a query. Presently you can get layer level query data (e.g. number of results) and of course spatial and non-spatial attributes for each feature. What's needed here is the mechanism to gather layer stats (and a definition of what those are) in either draw or query context and then a means of using or presenting them. Imaging in a new stats tag within a result set like so (within a resultset tag): [stats item=foo format=$stddev,$min,$max] You could use that to populate XML, JSON or just plain HTML output for use on the client. This tag would draw from a populated layerStatsObj which might consist of an array or hash of itemStatsObj's... You could populate those objects on-the-fly or perhaps even from a file. Would probably need a new STATS ... END block within a layer to drive this. Just thinking out loud.

Re: [mapserver-users] Continuing problem with WCS and ENVI Multi-band files
Hello, This has actually been resolved. I just haven't got back here to give an update until now. The proper mapserver use case for ENVI type rasters and WCS will be posted at mapserver.org by Frank Warmerdam once I get my 'stuff' together. There are some small sample ENVI test files available at: http://filebin.ca/cpaux/ENVI_test_files.ZIP NOTE: the files listed as ...int32... are actually ...int16... and the file name is a typo. These files (content) are not scientific data files but 6 band binary files with headers. The image data is a text burn in of the band number in each band on a zero background. The problem I was having with my WCS dataset LAYER definition seemed to clear up with some minor editing. There is a sample map file for UMN mapserver and ENVI format WCS located at: http://filebin.ca/upkmxs/mapfile.txt The geographic pixel size in the map file is incorrect. It should be 2.8125 degrees not 0.08333. The file is only 128x64 spatially. the band selection for GetCoverage URL is bands=number ie:(see end of URL line) http://somewcsserver.net/cgi-bin/wcs?REQUEST=GetCoverageSERVICE=WCSVERSION=1.0.0COVERAGE=BOGUStestDataCRS=EPSG:4326BBOX=-180,-90,180,90WIDTH=128HEIGHT=64FORMAT=GEOTIFF_FLOATbands=6 Hope that's useful.
