Re: [mapserver-users] maxscale (denom) with gml ?

2014-12-02 Thread bpicinbono

Thanks for the explanations and the ol3 solution, it's working perfectly.
Thanks again

WFS is meant to query raw feature data. Scale dependent rendering must be
controlled within the renderer itself - in this case using
minResolution/maxResolution options as described in
http://openlayers.org/en/v3.0.0/apidoc/ol.layer.Layer.html.

 Betreff: Re: [mapserver-users] maxscale (denom) with gml ?

 WFS runs through the MapServer query pipeline. Queries are generally scale
 independent except for cases where you are interacting with a source map
 (e.g. clicking on things), I mean, a scale computation requires both a map
 extent and a resulting image size. From that you can compute a cellsize
 and scale. I don't know if it's possible to force a scale computation
 somehow by passing a map size (in pixels) along with a map extent. or
 perhaps by passing the desired scale value directly (map.scaledenom?).
 Anyone have other ideas?

 I believe the query functions do respect min/maxscale (denom) values if
 the map scale is not set to -1.

 Many thanks for investigating;
 please check below the relevant parts of the mapfile, as well as the
 openlayers related code; (the purpose is to display nooa gfs winds
 forecasts,
 vents means winds in french);

 some stuff like the SYMBOL part and the layer's STYLE part should not be
 necessary anymore with gml output, as well as few other directives, clean
 up job
 ahead..., but working, minus the maxscale (denom) directive which is not
 working
 in this configuration;

 I could manage the scale display control on the openlayers 3 side with
 an if
 case based on the zoom level, but I would prefer mapserver mapfile to
 drive it;

 Thanks again

[mapserver-users] Is RFC 101 in Mapserver 6.4.1?

2014-12-02 Thread Luca Manganelli

As stated in this document:
http://mapserver.org/development/rfc/ms-rfc-101.html
the Content Dependent Legend Response should be integrated into MapServer.

GetLegendGraphics is fully working now; but now I tried to use HTML
legend templates. The RFC describes the CGI mode MAPLEGEND (that's not
documented, but LEGEND is). I am trying to have a html legend based on
the contents with this command:

http://local/cgi-bin/mapserv?map=map.mapmode=maplegendMAPEXT=X1 Y1
X2 Y2SRS=EPSG:25832

am I doing some error in this request?

Note that if I use  mode=LEGEND, it returns all the legend.

Thank you in advance :-)

Eduardo,
You don't provide more information about what are you trying to do, but I can 
suggest the following. In the LAYER section you must have a TEMPLATE label 
which must refer to a HTML file.

No tengo información sobre lo que intentas hacer, pero puedo sugerir lo 
siguiente. En la sección LAYER debes de tener una etiqueta TEMPLATE, la cual 
debe hacer referencia a un archivo HTML.
LAYER

TEMPLATE FOO.HTML...

[mapserver-users] An interesting SQL linestring building problem from postgres.

2014-12-02 Thread Basques, Bob (CI-StPaul)

All,

I have a bunch of individual LINE segments in Postgres and want to display them 
via MapServer like so:

First:

*  Get a chunk of them based on a set of IDs (a set of three for 
example)  and a begin/end timestamp (got this figured out already)

*  Take the result and combine up the separate line strings into 
multi-segment (grouped) lines ordered by ID, timestamp (got this figured out 
for individual IDs)

*  Add a random number to each grouping of multi-line string rows for 
dynamic color-coding of each group. (got this figured out for individual IDs)

*  Have results output as three rows, one for each multi-segment line.

I'm lost on the method to do the last piece.  Mostly it relates about how to 
approach which piece first.  Seems like a straightforward SQL, but I've tried a 
few different things, and it falls part each time for me.

Anyone have examples of something like this to start from?

The pertinent Mapfile fragment, I know this only color codes each individual 
segment at the moment.  VEH_IDs are passed into the MapFile from CGI 
(vname=veh_id in DB):

DATA the_line FROM (select the_line, vname, acqtime, trunc(random() * 4 + 1) 
rnum from loc) as foo USING unique vname using SRID=4326

FILTER  vname in (%veh_id%) AND acqtime  '%time_idx1%' AND 
acqtime '%time_idx2%' 

VALIDATION
'time_idx1' '.*'
'time_idx2' '.*'
'veh_id' '.*' ## veh_id='100','200','300' . . .
END

randomly.

If the goal is to just display them, then you do not need to create a 
multi-segment line, just display them as individual lines with the color 
attribute.


I you need them 'glued together' as a multilines for some other reason. 
then union should work.


select color, union(geom) from lines group by color order by timestamp;

Re: [mapserver-users] An interesting SQL linestring building problem from postgres.

2014-12-02 Thread Worth Lutz

I've done something similar.

I don't have it in front of me at the moment but a postgres select can
do this.

Look in Postgres for window and row_number.

You use the postgres OVER clause to group the items and then
row_number to get a key for color.

SELECT
a,
b,
c,
row_number() OVER (PARTITION BY d) AS color_key
FROM table

The partition is your grouping of three. row_number would be your
color_key. Use a modulus to limit the number of colors.

here is a link which might get you started
http://www.codeproject.com/articles/308281/How-to-Use-ROW-NUMBER-to-Enumerate-and-Partition-R

Note the final SQL statement which shows multiple items inside the
OVER clause.

I hope this helps point you in the right direction.

If I can find a second, I'll look at your problem a little harder.
