[mapserver-users] Using value from hstore column for labels

[Juanma M. R.]

Dear list,

I am trying to draw milestones from my OSM local database. The issue is
that in Nominatim database, the one I am ussing, I am trying to draw the
value "name" from a hstore column. How do I indicate this in mapfile in
labelitem? I haven't found the format to use a hstore data.

"name"->'name' obviously breaks the mapfile format.

Regards,
Juan Manuel Moreno Rivera.

Re: [mapserver-users] RE Rendering OSM data with MapServer+MapCache

[Juanma M. R.]

Hi Steve,

Thanks for your link. I will check it right now to see if I could learn
something about how to replicate the drawing styles from OSM servers but
using mapserver. The main problem is that the styles I use show less
information than the ones in OSM servers.

I only use basemaps to configure the mapfiles for OSM, but I don't know how
to do it to generate a mapfile that draws OSM servers styled maps.

Juan Manuel Moreno Rivera.

 [mapserver-users] Rendering OSM data with MapServer+MapCache






 Dear list,

 I have managed to install and configure succesfully a server showing data
 from OSM with the MapServer+MapCache convination. I followed these
 *instructions*
 https://github.com/mapserver/mapserver/wiki/Rendering-OSM-data-on-Ubuntu-12.04
  and
 some hacks that were necessary.

 The issue is that I have migrated from a mapnik+mod_tile server because
 some requirements that it didn't acomplished but the rendering of the map
 with mapnik was the same as the one shown in the OSM server.

 I also managed to configure a mapserver (without cache feature) with a
 .map file styling OSM but it is neither the one from OSM server.

 Does anyone know how to apply this style, the one from OSM server, to this
 data being renderd by MapServer? Does anyone done the migration from the
 OSM server style to mapfile or XML format for MapServer?

 Regards,
 Juan Manuel Moreno Rivera.

Re: [mapserver-users] RE Rendering OSM data with MapServer+MapCache

[Juanma M. R.]

Hi again,

I think that the link is based on basemaps but I don't know how to modify
the basemaps generate_style.py and Makefile to change maps drawing. It
seems that there is no documentation for customizing basemaps.

I will go on looking for it and maybe I will have to configure my map
adding part of the information with my own rules in the OSM servers style.
However it is extrange nobody has migrated OSM new style to mapserver
mapfile. It would be a good point for mapserver as OSM data server.

Juan Manuel Moreno Rivera.

[mapserver-users] Connecting to a mapnik / renderd / mod_tile layer

[Juanma M. R.]

Dear list,

I have a server offering OSM tiled layer based on the instructions here
http://switch2osm.org/serving-tiles/building-a-tile-server-from-packages/.

I have a openlayers using this OSM base layer and other overlay layers but
I would like to make them printable as an image or PDF. After trying with
client-side alternatives and failing one after another, I am trying now
based on a server-side and MapServer based approach, the one I am more used
to.

So, I have already configured the overlays layers in my map file and I need
to include the OSM tiled layer I have directly from mod_tile data. The
issue is that I can't find a way to do it. I am not familiar with mapnik,
that is why I am trying with mapserv which I installed on the server. Also
I would like to use mapserver to use the PDF, KML and multiple image
formats supported. I have always used mapserver, but I inherit this OSM
configuration and I found problems migrating or addapting it.

I have checked mapserver documentation, but following the instructions
in Rendering
OSM Data http://trac.osgeo.org/mapserver/wiki/RenderingOsmDataUbuntu it
fails when trying to compile mapserver-utils due to not being able to
connect www.naturalearthdata.com. However, here
http://trac.osgeo.org/mapserver/wiki/RenderingOsmData it says no
osm2pgsql estructure is supported anymore. So I am affraid I will need to
load data again to be able to serve OSM layer from MapServer.

Does anyone know if it is possible to connect to this mod_tile tiles from a
mapserver mapfile?

If no, does anyone know why mapserver-utils are failing and if there is
another tutorial for configuring OSM own server with MapServer?

Juan Manuel Moreno Rivera.

Re: [mapserver-users] Connecting to a mapnik / renderd / mod_tile layer

[Juanma M. R.]

Hi list,

I will answer partially to myself.

I have checked mapserver documentation, but following the instructions
in Rendering
 OSM Data http://trac.osgeo.org/mapserver/wiki/RenderingOsmDataUbuntu it
 fails when trying to compile mapserver-utils due to not being able to
 connect www.naturalearthdata.com.


Finally I downloaded the file mannually finding the correct URL:

cd data/
wget 
http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/cultural/ne_10m_admin_0_boundary_lines_land.zip
mv ne_10m_admin_0_boundary_lines_land.zip 10m-admin-0-boundary-lines-land.zip

I get compiling it and get the osm-google.map file containing the styles
for OSM. I copy them to my own mapfile and change the fonts to those I have
in my fonts directory for MapServer. And it worked! This way I sorted out
the problem of serving OSM data with MapServer.

I found another versión of the tutorial for serving OSM with MapServer
https://github.com/mapserver/mapserver/wiki/Rendering-OSM-data-on-Ubuntu-12.04
that
I feel is more up to date, but is almost the same content. I would
recommend this one if other people wants to serve OSM with MapServer.

About the issue of using the data from the mod_tile layer with MapServer, I
still need help on it. It would be helpful so that I do not have two
versions of OSM data, one based on osm2pgsql and the other based on impsom.
Also I would be able to avoid following this tutorial. At the end if I
can't find a working option I will replace the tiled OSM based on Mapnik by
this one based on MapServer to avoid duplicating data.

Cheers,
Juan Manuel Moreno Rivera.

Re: [mapserver-users] Geotiff OUTPUTFORMAT fails in browse mode

[Juanma M. R.]

Hi Steve,

First of all, thank you for your answer Steve.

I know it is old-style this way of requesting but I am trying to add
functionallity to a complex software based in this old-styled way of
working. I know that upgrading to the latest version of Mapserver would be
the best, however it implies resources and time that could be not
affordable right now as the existing and working map files would need
upgrade.

That is why I try working like that. I want to offer KMZ download and I was
trying to make a bridge to this format avoiding the upgrade of Mapserver by
updating GDAL, which can be done without having to update mapserver version
used by the system. Using the latest version of gdal_translate will make
affordable to get KMZ file from a GeoTIFF, for example, if I can store it
in the server side, which is what browse mode allows.

I know it sounds a bit complex, but updating the whole system is much more
complex and requires more efforts. Does anyone know why geotiff doesn´t
work in browse mode? Maybe is a limitation of these versions of mapserver,
4.10 and 5.6.6. If so, just knowing it would avoid me a lot of time
searching for it.

Cheers,

Juan Manuel Moreno Rivera.

  Browse mode is for old-style interactive clients. That is, user click -
 send to mapserver - mapserver builds new page. You wouldn't use
 mode=browse to create georeferenced output like you're doing. Mode=map or
 WMS are the way to go.

 *Subject:* [mapserver-users] Geotiff OUTPUTFORMAT fails in browse mode



 Dear all,



 I am trying to generate a georeferenced image with Mapserver. Now I am
 trying to do it with GeoTIFF.



 The issue is that all the outputformats are working in browse mode but
 GeoTiff. However, if I change to map mode, the URL request works and gives
 back the tiff data in stream to the browser.



 Is there any reason to GeoTIFF not working in browse mode, writting a file
 in the temporal folder from the server?



 My outputformat in .map file:



 OUTPUTFORMAT

   NAME GEOTIFF_16

   DRIVER GDAL/GTiff

   MIMETYPE image/tiff

   IMAGEMODE RGB

   EXTENSION tif

 END



 I have checked the compilation of mapserver having the --with-tiff in both
 cases. And it is ok but the



 ./mapserv -v



 returns:



 MapServer version 4.10.7 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
 OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER
 SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT
 SUPPORTS=WCS_SERVER SUPPORTS=GEOS SUPPORTS=POINT_Z_M INPUT=EPPL7
 INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE



 I don't know if this is relevant not having something like OUTPUT=TIFF but
 if no GeoTIFF support was included it shoudn't work neither in map mode,
 which works, should it?. The compilation was with no errors. This happens
 in both, Mapserver 4.10 and Mapserver 5.6.6.

I have tried with both, mapserver 6.02 and Mapserver 6.4. The main problem
is:

* How should I add support to KMZ in Mapserver? I have tried compiling from
trunk libkml (as explain here http://www.gdal.org/ogr/drv_libkml.html and

Re: [mapserver-users] Support to KMZ in Mapserver

[Juanma M. R.]

Hi again,

Finally I got the KML support working in gdal 1.10 and so I am trying now
to compile mapserver against it to get the KMZ support. I am trying to
compile 6.0.2 version but still there are problems with GDAL. After
compiling GDAL I configure Mapserver with the following parameters:

sudo ./configure --with-proj --with-geos=/usr/local/bin/geos-config
--with-ogr=/usr/local/bin/gdal-config
--with-postgis=/usr/local/pgsql/bin/pg_config

[mapserver-users] Re: pointObj-project behaviour differences from 4.10 to 5.6 versions

[Juanma M. R.]

Dear Daniel,

Thank you for your answer Daniel. I already know that the coordinate I put
was out of bounds for this limit. The issue is that I am trying to find the
best option to manage this change from one global CRS to a local one, as it
is necessary in my application. In version 4.10 it returned values for
local CRS and allowed to go back again to global ones. So it worked.
However, in version 5.6 it doesn't work at all. That is why I tried to
understand the way the function project works in the different versions.

After testing and your feedback, obviously I prefer the behaviour of the
5.6 that at least allows you to detect whenever a coordinate is out of the
bounds without having to check for each CRS bounds. In version 5.6 project
function returns the same coordinates when asking for transforming a
coordinate out of bounds for the output CRS. Checking if the function
returns the same coordinates helps you detecting this case and it is easier
to control it. I don't know if any other user in the list has deal with
this problem and used another way to implement it.

Best regards,

 EPSG:32630 is UTM Zone 30N ...

 http://spatialreference.org/ref/epsg/32630/

 A UTM coordinate system is defined for a limited area, a UTM zone has a
 width of 6 degrees of longitude, in this case

   EPSG:32630
   WGS 84 / UTM zone 30N
   WGS84 Bounds: -6., 0., 0., 84.

 It is very likely that you are getting random values from various PROJ
 versions because your -116, -15 test coordinate is outside of the area
 of validity of the EPSG:32630 coordinate system.

  Dear list,
 
  I have a webgis application working with different CRS all over the
  world. I have realized that the behaviour from version 4.10 of the
  function pointObj-project differs from the one of version 5.6 from
  Mapserver. For example, I try to convert (-116,-15) in 4326 and in

  (-26158630.407638,-25040425.679281) when passing to 32630. On the
  other hand, in version 5.6 of mapscript it returns the original
  coordinates without transforming them.
 
  Is this intended or am I doing something wrong? Which is the
  intended behaviour of project function in MapServer 5.6?
 
  Best regards

$pointObj-free();

[mapserver-users] Re: Problem in pointObj- project from php/mapscript

[Juanma M. R.]

Dear Daniel,

First of all thank you for answering so quickly.

Secondly, I must apologise for sending the email. It was my fault as I
understood wrongly the meaning of the coordinates in degrees. When referring
to them as Longitude and Latitude I misunderstood them. I know the values
they can get but I changed the correct place for Latitude / Longitude in the
x/y pointObj. Just reading your email (using easting and northing instead) I
understood my problem.

The pointObj-project method works perfectly in php/mapscript.

Sorry again for this email and thank you very much for your answer Daniel.

Best regards,
Juan Manuel Moreno Rivera.

 $pointObj-x is the longitude (a.k.a. easting), and $pointObj-y the
 latitude (a.k.a. northing). A value of -109 can only be a longitude,
 since latitude must be in the +/-90 range.

 What makes you think that the x and y are reversed?

[mapserver-users] Problem in pointObj- project from php/mapscript

[Juanma M. R.]

Hi list,

I have got the following code:

$pointObj=ms_newPointObj();
$pointObj-setXY($x,$y);
$pointObj-project(ms_newProjectionObj(init=.$srsIn),
ms_newProjectionObj(init=.$srsOut));

$xout=$pointObj-x;
$yout=$pointObj-y;


$srsIn is epsg:32612 and $srsOut is epsg:4326. The issue is that the point
modified has the correct value for the Y coordinate already converted in the
X field, and viceversa. So that I get a point with the X and Y coordinates
interchanged.

The input coordinates are:
$x = 642138
$y = 2983678

And the result:
$pointObj-x = -109.5678723348
$pointObj-y = 26.967831676085

I think this is not the expected result. I have checked it with mapscript
from  Mapserver 4.10 and 5.6.3. I have looked for a bug or something similar
that could cause that. Anyone with the same problem?

Cheers,
Juan Manuel Moreno Rivera.

[mapserver-users] Phpmapscript doesn't work with Postgis

[Juanma M. R.]

Hi list,

We are migrating our servers to a new server based on Centos and we are
suffering problems with the use of phpmapscript.

Postgis is working correctly when accessing from php but it fails when
executing the code bellow (our script is more complicated but I have removed
the other issues just to check what is failling and aboid side effect from
our code). The problem is that mapserver as cgi works correctly with the
same map file and the same layer and mapscript is compiled at the same time
than mapserver with postgis support (--with-php in the mapserver configure
options). The apache logs shows an Unexpected process ending with
Segmentation fault (11) error. The PostGIS log just sais that the connection
was broken unexpected by the client but doesn't give more details.

If anyone have any sugestion to follow up the testing and debugging, any
other way to try to find the problem or at least more details about what
could be failling, because we have no more ideas to get any clue about what
is happening.

Our configuration:

Mapserver 4.10.2
Postgres 8.3.5
PHP 5.2.6
Centos  5.2

Here is the layer declaration of the map file:

LAYER
NAME postgislayer
CONNECTIONTYPE postgis
CONNECTION host=localhost user= password=* dbname=*
DATA wkb_geometry from postgislayer using unique ogc_fid using SRID=32629
STATUS ON
TYPE polygon
CLASS
COLOR 0 0 255
OUTLINECOLOR 0 0 255
END
PROJECTION
init=epsg:32629
 END
METADATA
wms_title Test Layer
wms_srs epsg:32629
END
END


My php code is as follows (just the wms wrapper from mapserver
documentation):

?php
$req_cgi = ms_newOwsRequestObj();
if ($_SERVER['REQUEST_METHOD']==POST)
{
foreach ($_POST as $key = $value)
{
$req_cgi-setparameter($key, $value);
}
}
else
{
foreach ($_GET as $key = $value)
{
$req_cgi-setparameter($key, $value);
}
}
ms_ioinstallstdouttobuffer();
$oMap = ms_newMapobj($req_cgi-getvaluebyname(map));
$oMap-owsdispatch($req_cgi);
//$contenttype = ms_iostripstdoutbuffercontenttype();
if ($contenttype == '') header('Content-type: image/png');
else
{
$header = 'Content-type: '.$contenttype;
header($header);
}
ms_iogetStdoutBufferBytes();
ms_ioresethandlers();
