Re: [mapserver-users] MapServer on Intel Atom?
Just out of curiosity, With what reason would you like to have a mapserver on a mobile device? I assume mostly to have some sort of localhost connection from a local application, and in that case, I would opt for a solution where one can for instance download raster-tiles from a server to the mobile device that are then used by the application through more simplified functions, for vector the same procedure, download vectors and make them available through libraries. Installing a httpserver with mapserver as a cgi app sounds like a bit of overkill. Perhaps the mobile app can simply use gdal and ogr libraries. Dan Little wrote: I agree with where Jukka is going...

Re: [mapserver-users] Show WFS layer
Hi, i tried it, no luck here. I added some WMS specs in my mapfile, and i can see my two test records when i open the layer as a WMS in openlayers... but, if i may, let me ask another question... I'm very new in this technology, i'm just testing all this, because we want to now if we can develop ourself what our customer asks us, or do we have to 'buy' the solution from another company (who is more an expert is this kind of software). The requirement is simple: i need to show some raster data (will be delivered to me) together with positions of ships (that come from a database). The ships need to be clickable and of course, some information about the ship comes up (classic hugh ;)) Because of the heavy amount of ships ( 1000), i do not want to use javascript-code to add my objects. (our current project does that in Googlemaps, which act slow if many markers' are added) So, I'm able to show a WMS layer (based on my test shapefile). i guess if that works, i will be able to show some raster data aswell. Now comes the 'unknown' part for me. I know i can show my ships as an WMS layer, as a pure image, (i tested this) but can i add my clickable funtionality? or is a WFS layer better here...? i know the site mentions books to read about Mapserver, but the books date from 2005, are there any more recent good books out there?

[mapserver-users] Need help with build-order of libraries used by mapserver (UTF8 support, SDE, etc)
On Tue, 6 Jan 2009, Russell McOrmond wrote with Subject:
Re: [mapserver-users] Confirmation of status of UTF8 support,
and where transcoding to Latin-1 may be happening.
I hope people don't mind me posting as I learn things, hoping that it will
spark some ideas from other people.
Another issue, this time with iconv. I know this is not a mapserver issue,
but it is possible that someone has seen something similar.
As an update, I am still tracking this problem.
Like the binary created by the FGS folks http://maptools.org/fgs/ , we
are trying to compile mapserver against libraries we build ourselves so
that mapserver is not as dependant on the operating system environment.
The problem we are having comes down to some library incompatability
between iconv_open and some other library.
I have a simple test program.
#include iconv.h
int main() {
iconv_t cd;
cd = iconv_open(UTF-8, UTF-16);
printf(iconv_open returns %d\n\n, (int)cd);
iconv_close(cd);
return 0;
}
If I compile this against the standard libc (gcc iconvbroke.c ; ./a.out)
, then I get a value other than -1.
If I compile with the same linking that mapserver is using, then I
always get -1
My successful test had the following environement:
1) all libraries/etc built with sepatate libiconv
2) back up and then remove libiconv and separate iconv.h
3) rebuild libxml2 and mapserver (now not linked against libiconv)
4) restore libiconv files.
If I build my 'iconvbroke' test after these steps then I get numbers
other than (-1). That is, it is not linking against libiconv (as it was
removed in step 2), but is linked against a libgd that was built with
libiconv still there.
If I put libiconv back and build just configure and build mapserver, it
is broken again. This suggests it isn't just something specific to
libxml2.
If I leave the library there, but just don't restore the iconv.h, then
mapserver also seems to be fine (it's linked against libiconv likely
because of libxml2, but its own usage of iconv isn't using that version).
This seems a bit odd to me and I expect that there is something else
broken when things are built this way (IE: things that gd, xml2, and other
libraries are using). I'm just testing data coming from SDE, and haven't
yet re-tested things like labels/etc.
Here is a list of all the stuff we are building. Not all of these
components are libraries that mapserver links against, but it is complete.
I'd rather be complete than manage to not mention something that turns out
to be relevant.

difference as other binaries targeted for this environment are broken in
the same way.
Any suggestions greatly appreciated.

[mapserver-users] GPX format supported?
Hi Steve, Thanks for the rapid reply. I have removed the layers one by one. They all parse right but this GPX layer.

Still puzzled, bean Bean, You probably have some other layer that does not have the block ... ENDs match up correctly.

Re: [mapserver-users] Mapserver queries for line layer
Here's an example that uses OpenLayers with a hover event to fire queries off to MapServer: http://www.dnr.state.mn.us/waters/csg/index_copy.html The relevant javascript is at: http://maps.dnr.state.mn.us/waters/csg/current_test.js When ever the user pauses the app fires a query off to MapServer. In this case I'm querying points but the same code would work for lines. If the query fails (e.g. nothing found) I use the webObj EMPTY parameter to return content that just contains a -1. If it succeeds, templated query results are passed back and displayed. In this case I'm using an Ext.js window but you could just as easily update a div or use another popup library. Hope it helps...

Re: [mapserver-users] Where is the raster classifier code in Mapserver?
Very cool. Looks like it is scheduled for inclusion in Release 5.4., and even better, the code is still functional. I'm playing around with it now, and am easily applying a gradient to a single range of values, but have not yet figured out how to apply different color gradients to different ranges. Will keep working on it. Thanks for the lead. -- On Tue, Jan 13, 2009 at 2:02 PM, Frank Warmerdam warmer...@pobox.comwrote: Roger André wrote: This is probably a question for Frank W..

[mapserver-users] GPX format supported?
Hi Jeff, Thanks for the reply. I ran ogrinfo on both waypoints and track_points. waypoints returns 147 entries and track_points returns 0 entries (there are no tracks recorded in my GPS unit at this point, just trying to keep it simple for now). This is returned from a Garmin eTrex Venture through gps babel. Thanks for entering the SVN. I am still puzzled about my mapfile layer however. It fails to parse when CLASS is added and the layer fails to load when CLASS is deleted. I feel sure my mapfile layer syntax is correct (although my previous blooper with the errant END statement says I shouldn't be so sure). Would you mind looking for obvious errors for the following? LAYER NAME 'GPS' TYPE POINT CONNECTIONTYPE OGR CONNECTION '/Applications/MAMP/d/DATA/NonGrassFiles/GPX/gpsbabel_output.gpx' DATA 'waypoints' STATUS ON DEBUG 5 CLASS STYLE SYMBOL 'CIRCLE' SIZE 3 OUTLINECOLOR 0 0 0 COLOR 106 7 182 END END END Thanks, bean While testing gpx just now I realized that we don't have a GPX page in the MapServer Vector Data Access doc, so I have added it into SVN.

[mapserver-users] Can I turn off bounding box check for postgis query?
G'day all,
This might be a postgis list question, but I thought I'd try here first.
I have a table with approx 4 million rows, each with a date and start
and end point (and some other). This table would probably increase by
around 300 000 rows per month. The table is indexed and clustered by
date, and the table has no specific geometry information, just a code
to link to a geometry table.
To produce a useful sense of the activity, I am collecting all the
start and end points in a given time frame, and making line segments,
then aggregating by start and end point, and counting the total number
of each line.
EXPLAIN ANALYZE
SELECT
bucket::text,asbinary(force_collection(force_2d(route)),'NDR'),mid::text
from ( SELECT (ogid*1000 + dgid)::int as mid, origtta, desttta,
ST_MakeLine(s.orig, s.dest) as route, total_head,
ceiling(log(total_head))::int as bucket
FROM ( SELECT o.gid as ogid, d.gid as dgid, o.area_name as origtta,
d.area_name as desttta, st_centroid(o.the_geom) as orig,
st_centroid(d.the_geom) as dest, count(n.id) as total_head
FROM nlis n
JOIN tailtagarea o ON n.sourceshire = o.shortcode
JOIN tailtagarea d ON n.destinationshire = d.shortcode
WHERE sourceshire is not null AND sourceshire not like ' '
AND destinationshire is not null AND destinationshire not like ' '
AND transferdate = '13/06/2008' AND transferdate = '15/06/2008'
GROUP BY o.gid, d.gid, o.area_name, d.area_name,
st_centroid(o.the_geom), st_centroid(d.the_geom)
) AS s
) AS foo
in the terminal, this runs in either about 4 or 9 seconds depending on
the date range - if it becomes more than about 3 days of reports the
query analyzer notes moving to disk based sorts etc.
However, when I run it in MapServer, the following statement is added :
WHERE route setSRID('BOX3D(105.204213080645
-37.0327214193548,143.604244080645 -9.31123074193548)'::BOX3D, 4326 )
and it never completes, and neither does it if I take the final
statement and run it directly in psql.
So, I read the documentation, and read about moving the BBOX statement
using !BOX!, which I did (using st_within on both the joins, but in
fact, this is not the behaviour I want, as it stops any lines being
created if they start or end outside the window ( I want to see these
ones as well).
Additionally, it didn't stop the final bbox statement being added,
which I thought it was meant to?
So can I just trick MapServer into not adding the BBOX?
After aggregation, there is unlikely to be more than about 200 lines
to be rendered, so whether or not they are in the map window shouldn't
damage rendering performance too much - should it?
cheers
Ben
