[mapserver-users] Spatial queries to Mapserver
Hi all, Any one know of examples about how to call spatial queries using Postis functions from Mapserver? ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Spatial queries to Mapserver
Gabriel, You need to add a layer with your query in it - you can use variable substitution etc. an example (may or may not be a good one!) : LAYER DEBUG 3 NAME buffalo GROUP Movement METADATA layer_title Buffalo layer_order 2 END CONNECTIONTYPE postgis CONNECTION host=localhost port=5432 dbname=prices PROCESSING CLOSE_CONNECTION=DEFER DATA route FROM ( SELECT s.id, s.commodity, s.shortname, s.amount, s.purpose, s.origprov, s.destprov, ST_MakeLine(s.startpoint, s.endpoint) as route, to_char(s.origindate,'DD/MM/') as date FROM ( SELECT m.id, c.commodity, sp.shortname, c.amount, r.name AS purpose, initcap(o.name) as origprov, initcap(d.name) as destprov, ST_Centroid(o.geom) as startpoint, ST_Centroid(d.geom) as endpoint, origindate FROM movements m LEFT OUTER JOIN locations o ON m.originprovince = o.hiercode AND o.del = 0 AND o.level = 2 LEFT OUTER JOIN locations d ON m.destinationprovince = d.hiercode AND d.del = 0 AND d.level = 2 JOIN commodities c ON m.id = c.movementid AND c.del = 0 AND c.commodity = 2 LEFT OUTER JOIN species sp ON c.commodity = sp.id AND sp.del = 0 LEFT OUTER JOIN reasons r ON c.purpose::int = r.id AND r.del = 0 WHERE m.del = 0 AND originprovince is not null AND originprovince not like '0' AND destinationprovince is not null AND destinationprovince not like '0' ) AS s WHERE s.origindate '%start%' AND s.origindate '%end%' ORDER BY s.origindate ) AS foo USING UNIQUE id USING srid=4326 TYPE LINE STATUS ON HEADER 'templates/trade_header.html' FOOTER 'templates/trade_footer.html' CLASSITEM commodity CLASS NAME Buffalo EXPRESSION 2 STYLE SYMBOL arrow1 OFFSET 0 0 SIZE 12 COLOR 0 0 255 END TEMPLATE 'templates/trade_query.html' END END Actually, I don't think it's a great example, but it shows you how to create a line on the fly using the centroid (probably should have been point on surface) showing the direction the animals moved, within a user specified time frame. I'm open to any feedback on this - it's a modification of one I modified from one Regina Obe posted somewhere. I should say, note the use of debug. the error messages are invaluable when it doesn't work. good luck cheers Ben On 26/06/2009, at 2:47 PM, mapserver-users-requ...@lists.osgeo.org wrote: Subject: [mapserver-users] Spatial queries to Mapserver Hi all, Any one know of examples about how to call spatial queries using Postis functions from Mapserver? -- Ben Madin REMOTE INFORMATION t : +61 8 9192 5455 f : +61 8 9192 5535 m : 0448 887 220 Broome WA 6725 b...@remoteinformation.com.au Out here, it pays to know... ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] geotransform
Thanks, ANNOTATION layer is really doing the job. Charlotte PS : thanks to Thomas Bonfort to for his help Steve Lime a écrit : You can also use an ANNOTATION layer to do something like this. Depends if you need a true centroid or not. Annotation layers use label points generated from an algorithm that starts with a center of gravity computation. Subsequent tweaks are made if the point is too close to the edge. That approach guarantees the point will be in the polygon unlike with a centroid.

[mapserver-users] What has changed between 5.2.X and 5.4.X?
I am sure a lot has changed, but I do experience some weird and not welcome changes in rendered images for which there is no explanation in the documentation. For my application of Cartoweb 3.5 I am using a mapfile with the following: OUTPUTFORMAT NAME 'AGG_Q' DRIVER AGG/PNG FORMATOPTION QUANTIZE_FORCE=ON FORMATOPTION QUANTIZE_DITHER=ON FORMATOPTION QUANTIZE_COLORS=256 END The resulting images were small, aesthethically pleasant and color consistent with MS 5.2.1. version. With MS 5.4.X the images are even smaller (-20%), yet the colors vary from one image produced to the other. Even with the same extent and scale the colors change significantly for each consecutive map rendered. The colors may differ from what is set as a symbol color in the mapfile. Some symbols (e.g. circle) may loose their outline at certain scales (when using SYMBOLSCALEDENOM, MAXSIZE and MINSIZE). Both MS 5.2.X and 5.4.X were compiled with identical options and the mapfile is the same one. Many thanks for any clues or explanations in advance.

Hi, Have you tried to run the SQL queries from logfile directly? I wonder if for example this part is correct and finds any data: WHERE (geoidn='geoidNL.IMRO.0026.SVBBU-0001') and (tc_vlak_geometry setSRID( 'BOX3D(155984.407968748 468982.233317728,156024.590926508 469022.416275488)'::BOX3D,28992) ) Just a guess, but perhaps odd table name makes some trouble.

[mapserver-users] classification of a raster image is changing
Hello list, I have the following problem with UMNMapserver 5.2: I have interpolated some data with gdal_grid. As the result I got a tiff file with one band. In the next step i classified the raster image in UMN Mapserver like this: (..) CLASS NAME = 12 h EXPRESSION ([pixel] 9 AND [pixel] = 12) STYLE COLOR 65 182 196 END END (..) so far so good But if i view the image in a client like QGIS, the classification (colors) is changing depending on the chosen section (see appendix).

Here's one example using new-style templating (recommend
MapServer 5.4.1).
I'm using 5.2.0. Do I need to upgrade?
Well, I'd recommend 5.2.2 at a minimum simply because of the security upgrades
made in the last
few months. 5.4.1 is the latest version and contains a few fixes that fix
templates that have
multiple [item ...] or [shpxy ...] tags on a single line.
Anyway, please ask questions if you need to.
Ok!
The TEMPLATE:
// MapServer Template
function updateCountyList(element) {
var option;
...
}
So, where does this template go?
Good question, I guess that wasn't clear in my response. In this case the
template is separate file and is referenced in the OUTPUTFORMAT itself via
the FORMATOPTION/FILE option. In this example the actual template is
the file /templates/demo_county_select_list.js.
1) there is a TEMPLATE in the WEB section. It seems that if
that line is present, it gets used. I don't think it is
that template.
Correct, the web template is for defining a browse interface and really isn't
used all that much anymore.
2) There is DRIVER 'TEMPLATE' in the OUTPUTFORMAT section.
Should the above code be in a file named TEMPLATE?
3) There is a file in the FORMATOPTION under a /templates/
directory that looks suspicious.
Bingo...
4) There is a TEMPLATE in the LAYER section that is used to
indicate that the layer is queryable, and how to format that
layer's data.
The TEMPLATE keyword is still used to make layers queryable. That may change
in the future. Simple using something like TEMPLATE 'dummy' will suffice.
The OUTPUTFORMAT:
OUTPUTFORMAT
NAME 'county_select_list'
DRIVER 'TEMPLATE'
MIMETYPE 'text/javascript'
FORMATOPTION 'ATTACHMENT=county_select_list.js'
FORMATOPTION 'FILE=/templates/demo_county_select_list.js'
END
What is the difference in ATTACHMENT and FILE?
FILE is the actual template.
ATTACHMENT sets a HTTP header that essentially names the response from
MapServer.
In this case the browser would save the file as county_select_list.js. I'm
pretty sure this
is only available in 5.4 but isn't required at all.
The call to the CGI to run it is:
script
src=http://maps.dnr.state.mn.us/cgi-bin/mapserv54?map=demo.mapqlayer=count
iesqformat=county_select_listmode=nquery/script
Aha! qformat=name_of_the_output_format
Yup. You now can have a bunch of output formats without having to have a bunch
of layers
for each one. A layer's features can be referenced by any number of templates!
Thanks,
Wendell

Anyone has solution : - to remove the TEXT property ? I don't think there is a way to remove the text property with the current version. Could you please file a ticket and we'll try to fix that in the next release? It will likely be done by calling $class-setText(null) - to set the TEXT property with the attribute ? The following should work: $class-setText(([FIELD_NAME])); Okay, I'll admit that was not obvious. The TEXT parameter works differently from regular attribute binding. It actually goes through the logical expression parser, that's why there is a special setTExt() method and the round brackets are required.

Actually, no it doesn't require an integer type column for the UNIQUE clause. I have used text fields in the past with mapserver 5.x and can confirm that it does indeed work. Mind you, some other cartographic software such as QGIS does insist on int4 fields for PostGIS layers, but not mapserver.
