RE: [mapserver-users] Problems with non-square pixels
Hi,
thx for your answers.
It seems that possibility 2 solves the problem.
Although I can't understand wherefore this is only a problem for portrait and
not for landscape.
Now we have the problem that we do need exactly this BBOX because we want to
print a user given scale.
So is it possible to send a float width and height to mapserver or do we have
to change the logic in mapwms.c?
thx
best regards
Michael

Betreff: Re: [mapserver-users] Problems with non-square pixels
The nonsquare_enabled check is occurring *before* the WMS bbox (in
map-extent) is converted
to the MapServer extent model so I believe the code is correct. I'd lean
towards option 2 below.

Michael,
There seems to be a modest difference in the aspect ratio of the BBOX
and the SIZE in the given request. The logic in mapwms.c that tests whether
non-square mode needs to be used looks like this:
/* Check whether requested BBOX and width/height result in non-square
pixels
*/
nonsquare_enabled = msTestConfigOption( map, MS_NONSQUARE, MS_FALSE );
if (!nonsquare_enabled)
{
double dx, dy, reqy;
dx = MS_ABS(map-extent.maxx - map-extent.minx);
dy = MS_ABS(map-extent.maxy - map-extent.miny);
reqy = ((double)map-width) * dy / dx;
/* Allow up to 1 pixel of error on the width/height ratios. */
/* If more than 1 pixel then enable non-square pixels */
if ( MS_ABS((reqy - (double)map-height)) 1.0 )
{
if (map-debug)
msDebug(msWMSLoadGetMapParams(): enabling non-square
pixels.\n);
msSetConfigOption(map, MS_NONSQUARE, YES);
nonsquare_enabled = MS_TRUE;
}
}
I suspect the asymmetry is just enough to amount more than one pixel at
this size. I didn't run all the numbers but I suspect at smaller paper
sizes (smaller SIZE values) the assymmetry amounts to less than one pixel.
I'm not sure why it would affect portrait and not landscape. I only ran
the ratios on the case you mentioned was slow.
So there are a couple of possibilities here.
1) It is possible the above computation is wrong. I vaguely recall there
is an issue with map-extent actually being from the center of edge
pixel to the center of edge pixel, not the outer edges, in which case
the calculation should perhaps be:
reqy = MS_ABS(((map-width - 1) * dy / dx) + 1);
which might or might not make a difference in this case.
2) Perhaps you just need to generate your WMS requests with more precise
BBOXes corresponding to the aspect ratio of the SIZE requested.
Well, I'm sure there could be other possibilities too.

David, unfortunately, OFFSET behaves exactly the way you are pointing out, that is, it doesn't scale because it's values are expressed in pixels no matter what SIZEUNITS or SYMBOLSCALE. As to the task you would like to accomplish, though, what about making the image itself twice as tall and moving the symbol into the upper half of the image, thus having the center of your image located beneath the symbol itself? The image would still scale correctly and account for offsetting the symbol by itself.

Re: [mapserver-users] Scaling Image Symbol Offset
RFC 45 suggests several rendering improvements for Mapserver, including adding a tag (CENTER/ORIGIN) for specifying the centre of a symbol. This feature has, however, not been given priority yet (there are workarounds for the most important cases). http://mapserver.org/development/rfc/ms-rfc-45.html -- CENTER/ORIGIN [x y] Defines the centre of the symbol using decimal pixels (x axis increasing to the right, y axis increasing downwards). * Is used for placing a point symbol on the map or on a “decorated” line * Defines the center of rotation if an ANGLE is specified for point symbols. * Default value is the centre of the symbol’s bounding box. * Applies to TYPE ellipse, vector, pixmap, truetype. -- Håvard David Martin wrote: I am developing a new application and am rendering around a load of graphic symbol layers using a Map file layer such as LAYER NAMEcape_headland_point STATUS ON GROUP all DATA'ExplorOz/Places/Cape,Headland,Point' TYPEPOINT SYMBOLSCALE 100 CLASS STYLE SYMBOL [POIImage] MAXSIZE 15 MINSIZE 4 SIZE 8 END END METADATA wms_title Capes, Headlands Points END PROJECTION +proj=longlat +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +no_defs END END As you can see I am sizing the output symbol which is a 20x20px PIXMAP image – this is working great however the position of the image needs to be OFFSET up by half the size of the image (to make the actual point be the center of the image) – I have tried using OFFSET however when the image size changes (based on SYMBOLSCALE)the offsets are wrong.

Re: [mapserver-users] Performance in regular expressions or analternative way to select a list of features
Here's how I fixed this issue. I ended up regenerating the shapefile and dbf and adding a separate column with the grouping I desired. Now, my map file selects from that column, and the syntax is much simpler (by one or two orders of magnitude). I am happy with the results, however, I didn't get the chance to try out all the other methods because of lack of time. Thanks again, Adrian Adrian Popa wrote: Hello Steve, I haven't tried out the simplified regex so I don't know if it will be faster. I will try to test it as part of a speed test of the various methods... I'm not sure what you mean by writing a temporary set of geometries. Do you mean adding an index to my data so that I can select it by a different (grouping) field instead? Unfortunately I can't do that because the same item can be part of 10-20 groups, so there would not be an easy way to group items apart from duplicating them in the shapefile/dbf. I'm not sure if there's a problem if the same feature appears 12 times in the same shapefile. In the end data reorganizing might be the fastest method available. Problem is some items will belong to groups dinamically, so I will have to implement a selection mechanism based on item id... Regards, Adrian Steve Lime wrote: Have you tried a simplified version of your regex? I think you can do: EXPRESSION /^ITEM1|ITEM2|ITEM3|ITEM4$/ You might also consider writing a temporary set of geometries if a user will continually display from that set. In that case your overhead would be in managing the set of features which would be higher the first time but then very fast to render. Your dynamic portion of the mapfile would reference the temporary data.

This portion of the mapfile is dynamically generated and when it is done, it is sent to mapserver for rendering. My problem is that I have to select between 10 - 400 features at a time and I noticed when I have a lot of features there is a severe performance degradation in mapserver (takes a lot of time to render or even times out). Right now, my expression is built using regular expressions: something like: *EXPRESSION /^ITEM1$|^ITEM2$|^ITEM3$|^ITEM4$/* This works ok, but as I said has a performance penalty when you reach ~400 items. My data is selected from a shapefile layer which has about 5500 items. Since I wouldn't be using the regular expressions at full capacity (I'm matching the full name), I might rewrite the expression using something like: *EXPRESSION ( ([NAME]==ITEM1) OR ([NAME]==ITEM2) OR ([NAME]==ITEM3) OR ([NAME]==ITEM4) )* From the documentation I see that: /Regular expression with MapServer work similarly to string comparison, but allow more complex operation.

[mapserver-users] Changing to Layers.WMS from Layers.Mapserver
Hi, i am having trouble trying to display my map in Open Layers via
OpenLayers.Layer.wms.
Firstly I Built a shape file of the UK as a raster tileindex. I can now view my
map via //localhost/cgi-bin/mapserv.exe/mymapfile.map and the map looks fine.
I am now trying to view my map via OpenLayers. Firstly I used
Openlayers.Layer.MapServer which displayed my map however zoomed in very close.
However I have read Layer.Mapserver should be avoided and Layer.WMS should be
used instead.
I attempted to amend both my map and openlayers files to display via WMS by
Including:
METADATA
‘wms_srs’ “EPSG: 32119 EPSG: 4326”
END
within the WEB section of my map file and adding OpenLayers.WMS within my
OpenLayers file.
However I now get the following error message within the openlayers map window
“msWMSLoadGetMapParams(): WMS Server Error”
I also added ‘projection: epsg: 32119 epsg:4326” into my openlayers file which
hasn’t made any difference
Does anyone have any idea where I am going wrong? Any help greatly appreciated.
My map and openlayers files are below.

now
view my map via //localhost/cgi-bin/mapserv.exe/mymapfile.map and
the
map looks fine.
I am now trying to view my map via OpenLayers. Firstly I used
Openlayers.Layer.MapServer which displayed my map however zoomed in
very
close. However I have read Layer.Mapserver should be avoided and
Layer.WMS
should be used instead.
I attempted to amend both my map and openlayers files to display via
WMS
by
Including:
METADATA
wms_srs EPSG: 32119 EPSG: 4326
END
within the WEB section of my map file and adding OpenLayers.WMS within
my
OpenLayers file.
However I now get the following error message within the openlayers
map
window msWMSLoadGetMapParams(): WMS Server Error
I also added projection: epsg: 32119 epsg:4326 into my openlayers
file
which hasnt made any difference
Does anyone have any idea where I am going wrong? Any help greatly
appreciated. My map and openlayers files are below.
Cheers
p.s. I ahve installed ms4w on windows which i tihnk supports WMS

My map file now looks like this (i have hihglighted your changes in bold), do
you think i have put them in correclty?

Thanks for the quick reply.
You mentioned adding a projection block to the layer.
Is that done by the following:
PROJECTION
epsg:32119

Hi,
there are several things wrong here.
'wms_srs' epsg: 32119 epsg: 4326
should be (uppercase EPSG for METADATA and no space in between):
'wms_srs' EPSG:32119 EPSG:4326
however Mapserver cannot reproject your data if you do not add a
PROJECTION block to your LAYER stating the projection in which your data
resides.
Also, in OpenLayers the syntax is (your map can only be in 1
projection):
{projection: EPSG:32119}
Best regards,
Bart

[mapserver-users] reprojected layer = changed min/max scale ?
Hello This is probably a silly question but I cant find an answer for it. I have a mapfile with a given EPSG projection (EPSG:27582) In this mapfile I have a WMS layer with a different projection (EPSG:4326) when displayed, the max scale of the wms layer is different from the max scale value specified in the layer's definition in the mapfile so I would like to know, when mapserver does the reprojection of the wms layer from EPSG:4326 to EPSG:27582, the min/max scale are also modified in the process ? thanks in advance Oliver ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Problems with non-square pixels
Pfeiffer Michael wrote: Hi, thx for your answers. It seems that possibility 2 solves the problem. Although I can't understand wherefore this is only a problem for portrait and not for landscape. Now we have the problem that we do need exactly this BBOX because we want to print a user given scale. So is it possible to send a float width and height to mapserver or do we have to change the logic in mapwms.c? Michael, It is not possible to send floating point WIDTH and HEIGHT values to MapServer. I'm not sure why you want the exact BBOX instead of adjusting it a bit to reflect the actual aspect ratio of the raster requested, but if you feel strongly about it just let things go into non-square pixel mode.

[mapserver-users] duplicate labels
Hi All,
Here is a screen shot:
http://maps.camavision.com/map.jpg
There are, as far as I can tell, 4 lines. The label is duplicating and
I dont want it too. Here is the layer from the mapfile:
LAYER
NAME annotate_pin
TYPE line
STATUS on
CLASS
NAME HIGHLIGHT
STYLE
COLOR 0 255 0
OUTLINECOLOR 0 255 0
WIDTH 3
END
LABEL
TYPE truetype
FONT Vera
SIZE 10
COLOR 0 0 0
ANGLE follow
POSITION auto
BACKGROUNDCOLOR 255 255 255
MINDISTANCE 900
END
END
END
I have played with MINDISTANCE from 0 to 99,000 and it does not seem to
make a difference. I googled a little but have not found a useful answer.
I am adding features to this layer in perl mapscript using something like:
my $shape = new mapscript::shapeObj($mapscript::MS_SHAPE_LINE);
$shape-add($line);
$shape-{text} = sprintf('%.2f', $p1-distanceToPoint($p2));
$shape-setBounds();
$newlayer-addFeature($shape);
Any hints would be appreciated,
-Andy

AW: [mapserver-users] openlayers/mapserver
Hi,
with a right click on the pink tile you can get the url of the image. Test
it in the browser and you should get an error message.
Perhaps it's the wrong parameter SRS (it's a wms parameter) or the absent
parameter map_projection (mapserver parameter).
You should also declare options for your map object. I think by default
OpenLayers uses EPSG:4326 with the extent -180,-90,180,90.

[mapserver-users] Geo-Referencing questions
Alright, so after some great help last week from some people on this listhost, I have mapserver up and running on my local apache webserver. Now, however, I have tons of newbie questions, so sorry if these are painfully obvious/ignorant. I've spent a lot of time reading through documentation, and these are the things I still don't understand. My goal right now for the project I'm working is to use a .jpeg of my neighborhood, geo-reference it, and then get different line shapefiles with all the different bus routes and shuttles up. I have a bunch of questions in trying to accomplish this. First of all, I downloaded HyperCube and used Google Earth to get four longitude/latitude points that I could identify on my .jpeg of my neighborhood. Then used the Image to Reference Coordinates utility on HyperCube to add in this data, then resave this as a .tif. I was sort of skeptical that this could actually make it a geo-referenced TIFF file, so I called gdalinfo on it and got: /gdalinfo /Library/WebServer/Documents/TrialCampusMap.tif Warning 1: TIFFReadDirectoryCheckOrder:Invalid TIFF directory; tags are not sorted in ascending order Warning 1: TIFFFetchNormalTag:ASCII value for tag GeoASCIIParams does not end in null byte Driver: GTiff/GeoTIFF Size is 1439, 1804 Coordinate System is: GEOGCS[WGS 84, DATUM[WGS_1984, SPHEROID[WGS 84,6378137,298.2572235630016, AUTHORITY[EPSG,7030]], AUTHORITY[EPSG,6326]], PRIMEM[Greenwich,0], UNIT[degree,0.0174532925199433], AUTHORITY[EPSG,4326]] GeoTransform = -87.60760613250471, 1.981903295209896e-05, -7.648849138569716e-08 41.80965128643957, 3.093930015634964e-07, -1.475797871914549e-05 Metadata: AREA_OR_POINT=Point TIFFTAG_XRESOLUTION=72 TIFFTAG_YRESOLUTION=72 TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch) Image Structure Metadata: INTERLEAVE=PIXEL Corner Coordinates: Upper Left ( -87.6076061, 41.8096513) ( 87d36'27.38W, 41d48'34.74N) Lower Left ( -87.6077441, 41.7830279) ( 87d36'27.88W, 41d46'58.90N) Upper Right ( -87.5790865, 41.8100965) ( 87d34'44.71W, 41d48'36.35N) Lower Right ( -87.5792245, 41.7834731) ( 87d34'45.21W, 41d47'0.50N) Center ( -87.5934153, 41.7965622) ( 87d35'36.30W, 41d47'47.62N) Band 1 Block=1439x1 Type=Byte, ColorInterp=Red Band 2 Block=1439x1 Type=Byte, ColorInterp=Green Band 3 Block=1439x1 Type=Byte, ColorInterp=Blue First of all -- what are the differences between the two different sets of coordinates in parentheses for upper left/ lower left.etc. Next, is this actually a GeoTiff?

First of all -- what are the differences between the two different sets of coordinates in parentheses for upper left/ lower left.etc. Rebecca, The first set is reported in decimal degrees. The second set is the same values described in degrees, minutes and seconds with hemisphere codes (W=west vs. using a negative sign for instance). The values all look plausible. Next, is this actually a GeoTiff? It appears to be a valid geotiff though if the details of this were particularly important to you it might be better to inspect a listgeo report instead of a gdalinfo report. And moreover, what do I do with it now? I tried displaying it as LAYER NAME campusmap TYPE RASTER STATUS ON DATA TrialCampusMap.tif CLASSITEM [pixel] I have no idea why you are using CLASSITEM. Normally RGB images would be used directly with no classes or classitem defined in the raster layer. with a GeoTiff OUTPUTFORMAT and also with different types of files as IMAGETYPE. But each time, the image came out as horrible quality, I would encourage you to use an output format like PNG24 or JPEG to avoid significant color degredation. PNG or GIF will generally be inappropriate choice for RGB imagery. and oddly tilted (though it might be tilted so that the latitude line is the horizontal axis?). The photo is apparently not oriented north up, so MapServer is rectifying it on the fly. Based on the geotransform it seems the angle of rotation should be modest - perhaps a few degrees? Also, I wasn't sure what to use for the EXTENT, and used the numbers -87.60 41.75 -87.57 41.81 which seemed to display the whole map, but this was only after some trial and error with the upperleft/lowerleft, etc. data. How can I normally find the EXTENT? Normally you could find this by looking at the corner coordinates in the gdalinfo report. Second of all - I want to start adding some Vector layers, but the problem is that no shapefiles or anything exist for the data I want to add. I googled about a bit, but didn't find any good advice on how to make your own Vector data from personal knowledge. Can anybody point me in the right direction on this? My suggestion would be to draw them by hand over the photo image you have using software like QGIS for instance. Ensure that whatever software you use understands rotated geotiff files - this is not universal. If you want predefined local data you might want to discuss data sources with your campus engineering office, or your local city/municiple GIS people.

[mapserver-users] Error running ./configure on a Linux machine
Hello all. I have tried to compile MapServer 5.4.1 for the last few hours to no avail. I cannot get past the ./configure command for some reason. Any input will be greatly appreciated. Basically, my problem is that ./configure refuses to recognize some of the commands I give it for some reason (for example, --with-agg or --with-png). It also refuses to find files on the system when I specify paths. For example, /usr/sbin/httpd or /usr/bin/xml2-config. I have made sure that the files are there, installed correctly, running just fine and are accessible by the user running ./configure. Any ideas what might be the problem?
