[mapserver-users] Problems With Google Earth WMS view
Hello. I create a WMS for GE and I found some estrange things. In my Map file I don't define a background colour and I could like to be Transparent, but... At some levels I have the transparent image and at other levels I don't have it I don't really understand Wat is happening. I have 3 Layer in different zoom levels, The first One it's a line layer and the others are Points layers. And in some areas of my map I found problems with transparency If i put in some area i have the transparency but if i change a littel bit, the bacgruond becomes with. And just one question: can define a resolution for the output image? Thanks ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Hi,
Why don’t you write method for deleting png .mapserver will take care about
creating an image.I have C# code.
The below code will delete all the files form OutputDIR.
I hope it helps you. Or At least you can get some idea about your task.
Thanks and Regards
Venkat.
public void Deleteimages()
{
try
{
foreach (string f in System.IO.Directory.GetFiles(OutputDir))
{

Thanks for the quick reply,
When you run this function? after each requests ? but if so, the client is able
to read the image before you delete it ?

[mapserver-users] Mapserver wms-client to tilecache / mapfile definition
Hello list users, I'm wanting to setup a mapfile with a WMS/Tilecache as source. Is this possible? I already tried several configurations, but i cannot get an image back. The problem is the resolutions and extents that are requested from mapserver (monitored the results from tilecache to mapserver with httpmonitor). Is there any way to give mapserver these parameters? Below the part of my mapfile that defines the layer with a tilecache as source. Thanks already for replies. Greetings Gerben LAYER NAME om TYPE RASTER STATUS ON CONNECTION http://myserver/tilecache/tilecache.py?; CONNECTIONTYPE WMS METADATA 'ows_title' 'om' wms_srs EPSG:28992 wms_nameom wms_server_version 1.1.1 wms_format image/png wms_extent -2,30,30,65 END END Please read our E-mail Disclaimer at the Grontmij Corporate website ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] mapserver MSVC2005 development package available to download (was mssql2008 binary test package available to download)
Here is my daily snapshot including the fast cgi support:
http://vbkto.dyndns.org:1280/tests/release-1400-20081023.zip
I've created a development package to compile mapserver from the sources:
http://vbkto.dyndns.org:1280/tests/release-1400-dev.zip
You can use the following steps to compile mapserver.
1. Extract the contents to a directory (for example
C:\builds\release-1400-dev)
2. Open Microsoft Visual Studio 2005 Command Prompt
3. cd C:\builds\release-1400-dev
4. nmake -f makefile.vc ms MS_DIR=mapserver
BASE_DIR=C:\builds\release-1400-dev
5. nmake -f makefile.vc ms-sql2008 MS_DIR=mapserver
BASE_DIR=C:\builds\release-1400-dev
5. nmake -f makefile.vc ms-csharp MS_DIR=mapserver
BASE_DIR=C:\builds\release-1400-dev
This package is based on the development version of gdal and
mapserver, but you can download the stable version of gdal and
mapserver sources in the base directory if you require a stable
version build
In this case you must specify these directories for MS_DIR and
GDAL_DIR at the command like, like:
nmake -f makefile.vc gdal GDAL_DIR=gdal-1-5
BASE_DIR=C:\builds\release-1400-dev
nmake -f makefile.vc ms MSL_DIR=mapserver-5-2
BASE_DIR=C:\builds\release-1400-dev
If you require a corresponding package for the MSVC2003 based builds
let me know.
Best regards,
Tamas

Thank you very much, Tamas.
getFeature works fine now.
But can I ask you for one more favour. Could you compile with fastcgi
support (ideally with all ms4w production release flags) or share 'your
working buildkit' (this just will be great!, not only for me) because I
still have problems with compiling ms4w(( but I need sql2008 support feature
as soon as it possible for my work. I would be very appreciate.
Tamas Szekeres wrote:
Folks,
Yes, I've run into the same issue when using the getFeature method
with the driver. Here is the corresponding ticket I've created:
http://trac.osgeo.org/mapserver/ticket/2795
Attached the C# test case with this ticket:
http://trac.osgeo.org/mapserver/attachment/ticket/2795/Program.cs
I've fixed this issue in the SVN-trunk and the stable branch, here is
my daily snapsot of the binaries you can test with:
http://vbkto.dyndns.org:1280/tests/release-1400-20081018.zip
If you encounter further problems with the driver don't hesitate to
file a ticket describing the issue.
Just for a note: This driver doesn't make any character encodings with
the values retieved as plain byte arrays from MSSQL, however your
default database setting corresponds to the
1251 codepage, so explicit character conversion may be required in C#,
like:
byte[] bytes = Encoding.Convert(Encoding.Unicode, Encoding.Default,
Encoding.Unicode.GetBytes(shape.getValue(k)));
string str = Encoding.GetEncoding(1251).GetString(bytes);

Re: [mapserver-users] Mapserver wms-client to tilecache / mapfile definition
Not directly with Mapserver's built-in WMS client. You might get lucky with the GDAL WMS-C driver, but it has some assumptions (like all resolution ratios should be 2) that might not apply to your TileCache instance. http://gdal.org/frmt_wms.html Best regards, Bart Hello list users, I'm wanting to setup a mapfile with a WMS/Tilecache as source.

Sorry but i still not understand...

Re: [mapserver-users] Problems With Google Earth WMS view
Hi David, can define a resolution for the output image? No, but your can change the image size ( height and width ) in your GE Link. Default values are 512 X 512. You could change those to 1024 X 1024 and you'll get a nicer image. problems with transparency on different zoom level Are you using your own WMS service ? If so, I don't know which OUTPUTFORMAT you're using but I had png with agg and didn't have this problem. If you have more than one image/png MIMETYPE, put this one on top.

RE: [mapserver-users] disk space
Valerio,
I think that most people just set up a cron job or a scheduled job on their
server to delete all of the temporary images at some periodic interval. (e.g.
24hrs, 12hrs, 1hr) Your interfval would depend on the number of images that
you are generating, disk space, etc.
In the code that you use to delete the files, you may want to look at the
timestamps on the images and only delete images that are at least 1 minute old,
so you don't accidentally delete an image before it can be used by the page
that called it.
David.

[mapserver-users] result cache question
Dear List, I'm updating a spatial querying tool that follows a process something like: 1. Select set of shapes from layer A with n results: A[1-n] 2. Find shapes from layer B that within buffer distance D of selected shapes from A[1-n] In the existing code we get a result set of A[1-n], loop through the shapes and run the buffer query on B. Our result is then something like sum(BUFFER(Ai, B)) for i= 1..n. The same tool also supports other spatial queries...CONTAINS, INTERSECTS, etc...all with the same general process flow. The tool is PHP mapscript. Questions: 1. Is there a better approach? 2. Can I get a Min Bounding Rectangle of A[1-n] to pre-filter B? Would that help? Thanks, Josh ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Re: [MAPSERVER-USERS] Get Number of features returned by extent change(zoom)
Sure, the [NF] template tag will give you that number. You'd have to pass the bbox to MapServer with mode=nquery to get it.

Valerio,
I
think that most people just set up a cron job or a scheduled job on their
server
to delete all of the temporary images at some periodic interval. (e.g.
24hrs, 12hrs, 1hr) Your interfval would depend on the number of images
that you are generating, disk space, etc.
In the
code that you use to delete the files, you may want to look at the timestamps
on
the images and only delete images that are at least 1 minute old, so you don't
accidentally delete an image before it can be used by the page that called
it.
David.

Thanks for the quick reply,
When you run this
function? after each requests ? but if so, the client is able to read
the image before you delete it ?

Hi,
Why don’t you write method for deleting png .mapserver will take
care about creating an image.I have C# code.
The
below code will delete all the files form OutputDIR.
I
hope it helps you. Or At least you can get some idea about your
task.
Thanks
and Regards
Venkat.

{
try
{
foreach (string f in System.IO.Directory.GetFiles(OutputDir))
{
System.IO.File.Delete(f);
}
}
catch (Exception exp)

Dear
all,
I have a demo where I'm using mapserver cgi
interface. I'm using the browse mode so each time mapserver
receive a request, it creates a temporary png on the server
filesystem.
Do you know how and when i can delete those
temporary image since they are used only one time ?
An attacker could easily fill all the server
HD locking all the
system.
Thanks

RE: [mapserver-users] railroad map file
Mark, The old cartoline examples don't work with AGG. There was an example in the GIS/LIS workshop that uses a line style overlaid by a truetype pipe character. In the symbol definition, make sure that you set the gap with a negative value so the pipes will remain perpendicular to the line.

The most popular is TileCache. It's a WMS-C server. Of course, your AJAX request thing would have to be making WMS-C calls which it likely is not if you wrote it yourself. Another idea could be to roll your own, and that should be fairly easy. Replace your call to the mapserv binary with a call to a MapScript program that generates the same images. Then modify it to track the layer and extent, save a copy, and so on. In theory, fairly easy. :) -- Gregor Mosheh / Greg AllensworthBS, A+, Network+, Security+, Server+ System Administrator, Lead Programmer HostGIS development hosting services, http://www.HostGIS.com/ Remember that no one cares if you can back up, only if you can restore. - AMANDA ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
[mapserver-users] MS-SQL / OGR Query Length Problem
G'day all, In a nightmare scenario, to provide maximum flexibility for a client I am using php/mapscript (4.8) to generate and display mapfiles (not the nightmare bit) using OGR to connect to a MS-SQL Server (2003) Database... I would just like to say here the fact that this works is nothing short of brilliant. We can't use the mapserv.exe as they have a hang-up about security risks, but we can use php. Go figure! The real nightmare is in fact that we can get this all to work on the client's server, but can't work out how to do it locally (using ms4w and MSDE 2000), and so have very limited debugging information coming back to us - what we have been able to work out is that if we have a working file with multiple layers, the layers with short queries will work OK, but getting to a layer based on a long query breaks it. This was allowing us to create really great maps of all sorts of stuff (the database handles multiple projects), except when we made a seriously impressive SQL query (which returned exactly what we thought was right) the whole process died. Roughly, it would seem that between about 1600 and 1700 characters of SQL kills the process. It can be very simple query (just straight data), and shorter more complex queries work. cutting excess white space can make a difference. So, is it a limit of OGR or ODBC that I can't find any reference to. I can't see that it is a problem with SQL Server, and I have had (I think) longer SQL queries working using postgis... My question is, does anyone know where this might be breaking / happening? (bonus points if you know whether it is a configuration setting that we could tune!) cheers Ben -- Ben Madin REMOTE INFORMATION t : +61 8 9192 5455 f : +61 8 9192 5535 m : 0448 887 220 Broome WA 6725 [EMAIL PROTECTED] Out here, it pays to know... ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

Ben, I have reviewed the OGR ODBC driver and I see no obvious point at which a long query should be a problem. I have also skimmed the MapServer core and php_mapscript code and I see no obvious problem. I assume you are placing the SQL query in the DATA statement in the map file? I would suggest a few steps to try and isolate this: o See if you can reproduce it against other ODBC datasources. o See if you can reproduce it with mapserv instead of php_mapscript o See if you can reproduce it with just OGR and no MapServer. If you can reproduce the problem in a form that I can run at my end without undue complexity, I'd be willing to dig in somewhat deeper.
