In each LAYER, add:

PROCESSING  "CLOSE_CONNECTION=DEFER"

This tells mapserver not to close the connection.  So you still need to
specify the connection multiply, but that's not that big of a deal, and you
will get the performance gain.  This is documented here:

http://mapserver.gis.umn.edu/docs/reference/mapfile/layer

But there are some caveats, and you might find yourself needing to apply a
local patch.  For more details, see:

I think you're doing an unneccessary step here.  Assuming LATIN1 is a valid
alias for ISO-8859-1 as recognized by shp2pgsql, just use shp2pgsql -W
LATIN1 to do the conversion to UTF-8.  (Or if that doesn't work, use -W
ISO-8859-1.)

But my main point is that you can have shp2pgsql do the conversion, and
there's no need to pipe it to iconv.

Re: [mapserver-users] ArcGIS Image Server

[Dean Gadoury]

I don't know if you can connect directly, but are you able to serve the
rasters through WMS from the ArcGIS Server? If so, you can make WMS requests
with your UMN MapServer and get the imagery that way.

Greetings,
Is it possible to connect to an ESRI ArcGIS Image Server using UMN Mapserver?  
I can curently use vector data from the SDE, but their raster data is served 
from an ArcGIS Image Server.  
Any suggestions or examples, would be appreciated.

Re: [mapserver-users] grayscale shaded relief in mapserver

[Guillaume Sueur]

I've done a tileindex, and when I set the layer to polygon and data to 
my tileindex shape, it displays well. So I think it's not a 
georeferencing problem.


Does anything could render as null (transparent or white, depending of 
outputformat) some raster layer without any error ?


Thanks

Guillaume

[mapserver-users] Connecting to PostGIS only one time for all the layers

[Emilio Ponce]

I want to connect only one time to a PostGIS database, in order to
improve the efficiency of my mapfile. Now I'm connecting in every
layer with this lines:

"
CONNECTIONTYPE postgis
CONNECTION "host= ... "
DATA "the_geom from comarcas
"

Is there a way to do this only one time in all the mapfile using more
than one layer?

Re: [MAPSERVER-USERS] ASCII -> UTF-8 convert problems for importing (GIS) data

[Emilio Ponce]

I had the same problem, to convert Charset you can use this option of
the Shp2pgsql tool

shp2pgsql shapefile_name table_name | iconv -f LATIN1 -t UTF-8 | psql -d db_name

It converts the charset of the shapefile from LATIN1 to UTF-8

-W describes the input format.  The output format if you use it will be
UTF-8.  From the shp2pgsql(1) man page:

---
   -W 
  Specify the character encoding of Shapefile$-1òùs attributes. 
If this option is used the output will be encoded in UTF-8.
---

So no, you don't want to transform it from ASCII, because you clearly don't
have ASCII input, as ASCII does not have the characters you describe.

You need to find out what the input data is encoded in.  A very likely
candidate is ISO-8859-1 (aka Latin-1).

Take a look at the actual hex values of some of the non-English characters. 
(I use hexl-mode in emacs to do this, but there are plenty of other ways.) 
Compare them to ISO-8859-1, for example at either of these:

http://en.wikipedia.org/wiki/ISO_8859-1
http://anubis.dkuug.dk/JTC1/SC2/WG3/docs/n411.pdf

For the two examples you cite, we have:

0xC7 LATIN CAPITAL C WITH CEDILLA
0xEC LATIN SMALL I WITH GRAVE

Do they match?  But this is still a bit of a guessing game, because you
could find many matches and still not be right, e.g. ISO-8859-15 is very
similar.  A better way would be to look at the documentation for your input
data, or ask the provider of the data.

Re: [mapserver-users] Mapserver & Cartograms

[Christian Kaiser]

Sorry for the late answer.

We did release today a new Java application for cartogram creation 
(). I think the main problem for 
an implementation in an online MapServer application will be the 
computation time needed to create the cartogram. Technically, it should 
be possible to find a solution using one of the known algorithms. But 
you will have to handle a computation process which can take several 
minutes...

Hi there,

do you know of anybody or any mechanism to implement some cartogram

I thought about using an exisiting mapserver site to draw these kind of 
cartograms dynamically. That would be really cool...

[mapserver-users] Large Shape File Performance: Testers wanted!

[Paul Ramsey]

I'm looking for folks comfortable with patching and compiling to test
out a couple speed improvements in shape file access. Please leave
your comments on the ticket, thanks :)

Two performance patches at: http://trac.osgeo.org/mapserver/ticket/2282

Summary:

Performance patches radically improved the selective case and
left the un-selective case in reasonable shape.

Definitions of tests:

o Indexed: Render 20 features of 1.8M, using an index scan to only
 pull the features needed from the SHP file.  Tests the selective
data access case.
o Unindexed: Render 20 features of 1.8M, using no index. Forces
bounds from every feature to be read.  Tests the un-selective
data access case

Mapserver 5.0

  Indexed: 164ms
  Unindexed: 990ms

Mapserver SVN + SHX Patch

  Indexed: 48ms
  Unindexed: 1015ms

Mapserver SVN + Bitmap Patch

Re: [mapserver-users] grayscale shaded relief in mapserver

[Guillaume Sueur]

the TIF goes with a .TAB and its georeferencing informations. It looks 
ok with Qgis.

The mapfile is straight-forward :
 LAYER
 DATA "uploaded/AUbwV8_32.TIF"
 NAME "shaded"
 PROCESSING "COLOR_MATCH_THRESHOLD=3"
 PROJECTION
   "init=epsg:27563"
 END
 STATUS ON

 TYPE RASTER
 UNITS METERS
END

Thanks for your interest,

Guillaume

Re: [mapserver-users] Raster problems

[David Martinez Morata]

Thanks for your help!

But now I have a question?

I put my layer definitions and the SCALE values but...

When I use ArcGis to show my layers the SCALE values are not the same of the
values I define.

Example:
My Layer:

LAYER
NAME "RGV2_L2e_05kFR_Contenu"
 GROUP "Fond_Carto"
  STATUS ON
  TILEINDEX "RGV2_L2e_05kFR_Contenu/RGV2_L2e_05kFR_Contenu.shp"
  TILEITEM "Location"
  TYPE RASTER
  MAXSCALE 15001
#Definiftion du systeme de projection Lambert II Etendue code EPSG
PROJECTION
  "init=epsg:27572"
END
#Metadonnes du serveur wms
METADATA
"wms_title""Raster_05K"
"wms_srs""EPSG:27572"
END
END

Scale of View in ArcGIS 9.0 SP2 1:21
Sclae of view in gvSIG 1:20021
AutoCadMap I search the Scale but some times puts one Layer an sometimes
other ( random )

I don't think anyone got back to you...but maybe you should be

not sure what the problem is with your 'client', but I would make sure  
you use the mapserver utility sh2img to test your mapfile.  http://mapserver.gis.umn.edu/docs/reference/utilityreference/shp2img

  Use gdal_translate, http://www.gdal.org/gdal_translate.html, to chop
up your ECW files and output your parts as tiff.  I'd suggest using python
to get the extent and pixel size ( in projection coordinates) of each image
and have gdal_translate grab a 10k X 10k chunk starting at the lower left
corner of the image, incrementing the x coordinate by (10k * number of
units per pixel) as you work left to right.  After you finish that row,
start back at the origin x coordinate and increment the y coordinate by
(10k * number of units per pixel).  Rinse and repeat until you finish the
whole image.

  It might be worthwhile to implement a bit of overlap ( 10-15 pixels)
in the x and y direction as you chop.

I fear that WFS itself does not support this well.  WFS does have a setting for 
maximum number of features returned by one request, but there is no way to ask 
for the following set of features starting from, let's say, feature number 
11. But if you take the WFS fid from sequential database field and sort 
that somehow then it should be possible to reach what you wand by addind a WFS 
filter like "AND fid>max_fid_from_last_request" to the next WFS request.  I can 
imagine that this could lead to most unuseful result if bounding box is also a 
part of a filter and user is panning around on the map between the requests 
(area unvisited before can have features with lower fid values).

Re: [mapserver-users] QueryByPoint problem: why always the same feature?

[Pietro Giannini]

Carlo,
I think the cache is refreshed each call of $layer->queryByPoint(point,
mode, buffer).
Remember to set the "mode" = MS_MULTIPLE to obtain more than one result,
the point is a $pointObj in GEOGRAPHIC coordinates, the buffer set to 0
get the default of the TOLERANCE (in pixels) of the mapfile, otherwise you
can specify in ground units a circle around the point for obtain the
results.

Look here:
http://mapserver.gis.umn.edu/docs/reference/phpmapscript-class
for a good guide about.

here a piece of code (it work):

$res = @$layer->queryByPoint($qpoint,MS_MULTIPLE,0);
if (@$layer->getNumResults() > 0) {
$layer->open();
for ($i=0;$i<$layer->getNumResults();$i++) {
$resCache = $layer->getResult($i);
$shape = $layer->getShape(-1,$resCache->shapeindex);
echo $shape->values['fieldname']."";
//  etc.
}
$layer->close();
}

ciao

[mapserver-users] QueryByPoint problem: why always the same feature?

[Carlo Pelliconi]

Hi all.
I use PHPMapScritp with Mapserver 4.10 on Debian Etch.
I do a series of querybypoint, but the answer is always the first feature!
I think it could be a resultCacheMember problem. How can I free all 
cache about previous query results?
New results of next query are appended to previous results or getResult 
goes to a new set at any new query?  
It is sufficient to close the queried layer ad to free the 
$shp=getResult(...)?

Thank you very much.

[mapserver-users] WMS with selected country rectangle box display?

[Stefan Schwarzer]

Hi there,

we have developed a WMS which receives a parameter for a selected  
country, producing a map which highlights the selected country, and  
masks a bit the neighboring ones. Now, I would like to create in  
conjunction with this one another WMS, which shows the world as a  
whole, and - as any overview map is doing - displays just a rectangle  
to locate the selected country on the map.


Is this possible as WMS? I have no idea how this would work...

Thanks for any hints,

[mapserver-users] PHPmapscript mouse click

[Carlo Pelliconi]

Hi all.
I'm using PHPMapscript on Mapserver 4.10.
I'm not able to get mouse click coordinates (in pixel).
Anyone knows how to obtain these values?
Thank you very much
