[mapserver-users] WFS Spatial Filter Problem

[Bryan Hempen]

The problem: I am trying to implement something similar to 
http://openlayers.org/dev/examples/wfs-spatial-filter.html with my own 
data served by MapServer through a WFS. I just changed some lines in the 
code to make it work with MapServer, so the code is almost equal to the 
code in the example at the moment. So far it's working fine UNTIL I drag 
the polygon to apply the spatial filter! According to the 
getCapabitilies the server should be able to handle the request:


...














...

Both WFS GetFeature requests are sent via HTTP POST. The first one that 
works (called on page load) looks like this:


http://www.opengis.net/wfs"; xmlns:xsi="http  
://www.w3.org/2001/XMLSchema-instance" service="WFS" version="1.0.0"

Does anyone have an idea? Any help is appreciated, I am stuck.

   * OpenLayers, one of the latest versions. ProxyHost set and working

[mapserver-users] Missing 1/2 a raster image in Google tilemode

[forums]

I have a GeoTiff file with an extent of:

Upper Left  (   0.000,  90.000) (  0d 0' 0.01"E, 90d 0' 0.00"N)
Lower Left  (   0.000, -90.000) (  0d 0' 0.01"E, 90d 0' 0.00"S)
Upper Right ( 360.000,  90.000) (360d 0' 0.00"E, 90d 0' 0.00"N)
Lower Right ( 360.000, -90.000) (360d 0' 0.00"E, 90d 0' 0.00"S)
Center  ( 180.000,   0.000) (180d 0' 0.00"E,  0d 0' 0.01"N)

I set the extent in my map file to:

EXTENT 0 -90 360 90

When I set "&mode=map" the full image displays as I would expect it.
But when I incorporate it into a Google Maps API using
"&mode=tile&tilemode=gmap" only the part of the image to show.  Only
the Eastern Hemisphere shows on the map.

I tried gdal_translate  to alter the corners, which shows the whole
map, but East/West hemispheres are swapped.

Are there any tricks I can do to get the whole thing to display?
I'm thinking I might have to some how programmaticly swap left/right
sides of the raster.

Thanks, I appreciate any insight anyone might have.

[mapserver-users] tile4ms throwing msSmallMalloc() Error

[Joe Marlin]

Hello! Quick question:

I'm running "tile4ms roadwaylevel5_meta.txt roadwaylevel5_index", where 
roadwaylevel5_meta.txt is simply my list of shp files:

And getting: "msSmallMalloc(): Out of memory allocating -4 bytes."

What does that mean? Why am I getting that? I've already tried:

-Compiling from SVN
-Compiling 6.0.1 from the website
-Trying on a different machine
-Trying to run the command with sudo


The documentation says "no extensions" in the input file; however, the examples 
in that exact same documentation page DO have the ".shp" extension. If I remove 
the extensions from my shape files, I get: "Aborted. Unable to open 
DBF:./roadwaylevel5_index". ./roadwaylevel5_index.dbf is created, and left 
empty when this happens. Running with sudo makes no difference. 

Thanks for your help, and sorry if I'm missing anything obvious!

[mapserver-users] advice on books

[John Callahan]

Can anyone point me to a good book on learning Mapserver, and possibly
OpenLayers as well?   I don't usually buy books on software products as
there's so much available online.  However, I recently purchased PostGIS in
Action and it's helped significantly.  I wonder if there's a similar quality
book out there on Mapserver.  Something higher than intro level would be
preferable.  Thanks.

- John

RE: [mapserver-users] advice on books

[PORTER . DANIEL]

John,

I believe there is only one English book out on OpenLayers, called "OpenLayers 
2.10 Beginner's Guide" 
(https://www.packtpub.com/openlayers-2-1-javascript-web-mapping-library-beginners-guide/book),
 which as the name says, it's a beginner's guide.  He assumes little technical 
knowledge, which makes it very good for getting your bearings.  If you can 
figure out what to do from the OpenLayers examples and API docs, I don't know 
that it has much to offer.  If you're struggling with that, I think it would be 
excellent (disclosure: I worked with Erik, the author of the book).

I have read that this mapserver book is somewhat outdated: 
http://www.amazon.com/Beginning-MapServer-Source-Development-Experts/dp/1590594908
  I have not seen it, though.  It's the only one I know about.

Re: [mapserver-users] advice on books

[John Callahan]

Thanks Daniel.  The OpenLayers book looks interesting.  Even though I
typically do fine with online examples, it's probably worth the purchase,
especially since I may be migrating several Google Maps apps to OpenLayers
at some point.

That Mapserver book is from 2005, I agree a bit too old but the only one I
can find as well.   Luckily the Mapserver documentation wiki has everything
we need!

Re: [mapserver-users] KML output and timestamp

[Yewondwossen Assefa]

Sorry for the delay.
It is not supported for now. I have added trac bug on it [1].
You are right that similar mechanism (in terms for metedata) can be used 
to extract time specfic value for the attributes and write it to the kml.


best regards,

Hi all,

do you know if Mapserver support KML Timestamp for KML output.
http://code.google.com/apis/kml/documentation/time.html

The documentation (http://mapserver.org/output/kml_output.html) says
TimePrimitive:  No
but it's kinda strange because Mapserver supports WMS Time.

Thanks.
