[mapserver-users] RE: Random colours for polygon fill?
Robert, It may be that the SDE plugin does not allow insertion of the Sql fragment from the COLOR to be executed by the provider. In such a case the solution provided under separate cover by B. Heath Robinson might provide guidance. I do not know if the ArcGIS Server lets you use a view as a data source; if so you could add a calculated column to yield the RGB string (either as a hexadecimal valye as suggested by Heath) or as a string with space-delimited R, G and B values. FWIW the approach I had suggested worked in MapServer 5.6.2 against Sql Server 2008; beyond that I've not tried it. - Phil From: Robert Sanson [mailto:robert.san...@asurequality.com] Sent: Wednesday, July 06, 2011 4:48 PM To: Anzel, Phil - Fort Collins, CO; mapserver-users@lists.osgeo.org Subject: RE: Random colours for polygon fill?

For example, in the following example the source data, pulled from a Microsoft Sql Server database, has an integer column named ShapeID: layer name mupolygon status on connectiontype plugin plugin C:/ms4w/Apache/specialplugins/msplugin_mssql2008.dll processing CLOSE_CONNECTION=DEFER connection server=...; projection 'init=epsg:4269' END # NAD83 units DD DATA shapeGeometry from soilmu_a_wy721_nad83 using unique shapeID using SRID=4269 type polygon opacity 40 class name mupoly style COLOR [convert(varchar(3), (128 + shapeID) % 253) + ' ' + convert(varchar(3), (200 + shapeID) % 254) + ' ' + convert(varchar(3), (64 + shapeID) % 255)] outlinecolor 0 0 0 outlinewidth 1 end end # of class mupoly end # of layer mupolygon In the context used above, the content of COLOR's specification (everything between the square brackets) is passed on as part of the SQL statement generated and transmitted to the database engine. Many variations are possible. Note that this approach does not provide any protection against the unlikely case where adjacent polygons display the same color. I cannot speak to using data from other data sources.

RE: [mapserver-users] Symbol not showing up in MapServer 6.0.0-beta1 release
Hi, Thomas, Thanks for looking into this problem. My goal is to create a railroad cross-hatching along a line. I originally used: SYMBOL NAME 'default' Type simple END SYMBOL NAME 'tie' TYPE vector POINTS 0 0 0 7 -99 -99 7 0 7 7 END END These were referenced, within a layer of type line, by: CLASS STYLE SYMBOL'default' SIZE 1 COLOR 0 0 0 END STYLE SYMBOL 'tie' SIZE 8 COLOR 0 0 0 END END This had worked under MapServer 5.6.3. I returned to this example after upgrading to 5.7DEV on March 9, 2011, and found that the tie cross-hatching had disappeared. I tried several other symbols; I used the circle as an example because it also worked in the past and is used in the MapServer Introduction to MapServer, section 2.4.3, CLASS and STYLE objects. Closer to the 2.4.3 example, if I define: symbol name 'circle' filled true type ellipse points 0 0 1 1 end end and reference this definition, as per the example, with: style symbol circle color 178 114 1 size 15 end style symbol circle color 254 161 0 size 7 end then there is no image created. Given these experimental results, I wonder if there has been a change in behavior in drawing symbols. Alternatively I've made a very simple error. Is there an error in my map file?

As you mentioned, MS4W is designed for new installations and contains a ready to use Web server and everything you need to move forward. If you need to use MS4W in an existing environment, there are some options: - follow the existing notes to install in other environments in your local README file (http://www.maptools.org/ms4w/index.phtml?page=README_INSTALL.html#k-installing-the-ms4w-mapserver-binaries-in-other-environments) - search the MS4W mailing list for other users asking this same question and the responses (search at: http://osgeo-org.1803224.n2.nabble.com/ms4w-users-f4995553.html) - contact me directly for assistance Hope that helps. -jeff -- Jeff McKenna MapServer Consulting and Training Services http://www.gatewaygeomatics.com/ On 11-01-20 7:51 PM, David Hildebrand wrote: The installation package for ms4w contains a preconfigured version of Apache.

I'm guessing that the input JPG file is opened for reading by MapServer and is never explicitly closed, even when the layer is closed. Is there a method defined in the API that will force the closure, if that is even the situation? Phil, In recent versions MapServer aggressively keeps single raster files used for raster layers open even after the map is destroyed in order accelerate the next access to it. This can be controlled/disabled by adding the following line in your raster layer: PROCESSING CLOSE_CONNECTION=NORMAL The default setting is DEFER for raster files.

[mapserver-users] MapServer distro site down at http://vbkto.dyndns.org/sdk ?
Hi, All,
The MapServer distro site at http://vbkto.dyndns.org/sdk may need a bit of
attention; all I get is a page with an amber background (full, yet incomplete,
HTML shown below). Problem observed 19:00 UTC 7 Jan 2010.

[mapserver-users] Feature points not drawn by 5.7DEV drawmap.exe
Happy New Year, All, Appended below is a short map file containing two layers: points and grid lines. The projection used by the map as well as the two layers is Web Mercator. When drawn with drawmap.exe from MapServer 5.6.3, all points and grid lines are shown. Using drawmap.exe from 5.7-development, the points are not shown. The 5.7-development drawmap.exe, with associated DLLs, was downloaded from http://vbkto.dyndns.org/sdk/ on 12/15/2010. I'm using the release-1600-gdal-mapserver.zip file created for VS2010/Win32. The same point omission occurs if I use the mapObj from mapscript_csharp.dll, load the map file, and execute a Draw to generate an output byte array. Is there an error in this map file? Is the difference an artifact of changes planned for 6.0, and if so, where might I find relevant documentation? Thanks, - Phil Anzel (Web Soil Survey developer for USDA/NRCS) ...start of map file...

[mapserver-users] Polygon outline not drawn in PDF output if polygon is not filled

This second issue with the Width parameter is due to the fact that the parameter is not supported in the PDF driver. The intention is to depreciate the current PDF support and use the Cairo PDF driver for the 6.0 release [1]. At that point we should have support for things like width, color/fill-color, ... be consistent between all output drivers. You could maybe try using MapServer from svn and try the Cairo support and see if that solves your immediate needs. regards, [1] http://trac.osgeo.org/mapserver/wiki/60ReleasePlan Case 1: Unfilled polygon, PDF output: As written above, the PDF output is empty.

[mapserver-users] PDF and SVG only shows last georeferenced raster layer
Hi, I think there is a defect when using multiple raster data layers with PDF or SVG image formats: only the last geo-referenced raster layer is drawn. This problem does not exist if the output is PNG. To demonstrate this problem, retrieve two adjacent JPEG tile files from Microsoft's Virtual Earth, using URLs: (west tile) http://ecn.t0.tiles.virtualearth.net/tiles/r021323222.jpg?g=409mkt=en-USshading=hilln=z (east tile) http://ecn.t0.tiles.virtualearth.net/tiles/r021323223.jpg?g=409mkt=en-USshading=hilln=z The tiles should be saved as files r021323222.jpg and r021323223.jpg, respectively. Create world files to accompany these. For the west tile, create r021323223.wld: 305.748113140705 0.00 0.00 -305.748113140705 -11897270.5785311 5087648.60266133 For the east, create r021323223.wld: 305.748113140705 0.00 0.00 -305.748113140705 -11818999.0615671 5087648.60266133 Here is the map file, with the addition of a red outline around the west tile and a green outline around the east one: MAP IMAGETYPE png SIZE 512 256 CONFIG 'PROJ_LIB' 'C:\ms4w\proj\nad\' PROJECTION 'init=epsg:3857' END # Web Mercator EXTENT -11900270.578531099 5006377.08569731 -11737727.5446031 5090648.6026613303 UNITS meters LAYER NAME 'left_tile' # retrieve from http://ecn.t0.tiles.virtualearth.net/tiles/r021323222.jpg?g=409mkt=en-USshading=hilln=z data 'r021323222.jpg' type raster status on END LAYER NAME 'right_tile' # retrieve from http://ecn.t0.tiles.virtualearth.net/tiles/r021323223.jpg?g=409mkt=en-USshading=hilln=z data 'r021323223.jpg' type raster status on END LAYER NAME 'left_outline' STATUS on TYPE line FEATURE #...right edge shifted left 153 meters (about half a tile pixel) WKT 'LINESTRING( -11818999.0615671 5009377.08569731, -11897423.578531099 5009377.08569731, -11897423.578531099 5087648.60266133, -11818999.0615671 5087648.60266133, -11818999.0615671 5009377.08569731)' END CLASS STYLE COLOR 255 0 0 END END END LAYER NAME 'right_outline' STATUS on TYPE line FEATURE #...left edge shifted right 153 meters (about half a tile pixel) WKT 'LINESTRING( -11818846.0615671 5009377.08569731, -11740727.5446031 5009377.08569731, -11740727.5446031 5087648.60266133, -11818846.0615671 5087648.60266133, -11818846.0615671 5009377.08569731)' END CLASS STYLE COLOR 0 255 0 END END END END Note that for PNG output, both tiles are shown. If you change the image type to SVG or PDF, only the last raster layer, the east tile, is shown. Is this a defect? Short of externally aggregating the source bitmaps into a single bitmap outside of MapServer, is there a possible workaround? Is this associated with failure of OPACITY to work with SVG and PDF?

[mapserver-users] Mapserver 5.6.3, IIS, and thread safety
All, As per http://www.mapserver.org/faq.html#is-mapserver-thread-safe , various parts of MapScript, and presumably its invocation via the C# wrapper API, are not thread safe. We're experimenting with use of MapScript in the form: map = mapscript.msLoadMapFromString(mapFileText, null); imageObj imageObj = map.draw(); byte[] img = imageObj.getBytes(); This is to be performed inside of C# code, offered as a Web Service by IIS under some enterprise flavor of Windows 2002 or beyond (but not Windows Vista or beyond). Under Apache, I've heard that a pre-fork worker could be used to maintain sufficient isolation between Apache MapServer server processes. Can anyone advise whether this is correct, and what a suitable IIS configuration equivalent would be?
