[OpenLayers-Users] OpenLayers 2.9.1 released

[bartvde]

The OpenLayers Development Team is proud to announce the release of
OpenLayers 2.9.1, the first bug fix release of OpenLayers 2.9.

Since the 2.9 release 3 regressions have been fixed, as well as 2
documentation errors:

 * Protocol.HTTP: PUT and DELETE should use url from options (#2393)
 * do not use getDimensions anymore, but use offsetWidth and offsetHeight
(#2414)
 * Rotated graphics are positioned incorrectly when moved or zoom changes
(#2596)
 * preload default value is incorrect in Strategy.Fixed documentation (#2611)
 * isBaseLayer default value is incorrect in Layer.Vector documentation
(#2613)

For information on possible changes that will need to be made between
this version of !OpenLayers and previous versions, please look at the
Release notes, available at the Release Notes information [1].

Re: [OpenLayers-Users] measure layer

[bartvde]

I think you need to create your own vector layer, and then listen to the
measure event. In the event handler you can create a feature using the
geometry returned and add it to your layer.

Bart

[OpenLayers-Users] upcoming 2.9.1 release

[bartvde]

Hi list,

because of a regression found in OpenLayers 2.9 (related to rotation of
vector features in the SVG renderer, see
http://trac.openlayers.org/ticket/2596 for details), we are planning to
release a bug fix release soon (somewhere next week).

Therefore we invite you to test OpenLayers 2.9 in your applications and
report any regressions (i.e. things that worked in 2.8, but not in 2.9)
through the OpenLayers Trac using Milestone 2.9.1.

Thanks in advance.

Best regards,
Bart

Re: [OpenLayers-Users] Spatial Filter parameter for WFS GetFeature

[bartvde]

The control fills in the value as I said before.

Please install Firebug and check the request generated by OpenLayers and
sent to your WFS.

Re: [OpenLayers-Users] Spatial Filter parameter for WFS GetFeature

[bartvde]

Hi,

you need to specify filterType. The control will take care of providing
the values. So:

var control = new OpenLayers.Control.GetFeature({
  ..
  filterType: OpenLayers.Filter.Spatial.INTERSECTS
  ..
});

Best regards,
Bart

Re: [OpenLayers-Users] control.SelectFeature

[bartvde]

I've got some code lying around to do circle selection with the GetFeature
control. If anybody is interested I can open up a ticket with a patch.

Some handlers have a persist option which indicate whether or not the
drawn geometry should persist (not be cleared after drawing), however the
box Handler (used by the GetFeature Control in box mode) does not have it
currently.

Circle uses the RegularPolygon handler, and that one can persist if you want.

Best regards,
Bart

Re: [OpenLayers-Users] IE8 problem with VMS

[bartvde]

How many features are you rendering, and how complex are there geometries?

VML is known to be slow unfortunately, so you're easily running into the
browser's limits here.

Hi,

not sure if this is the cause of your problem since I don't know anything
about EPSG:2498, but can you try adding xy false to your Format.GML:

 var isoline = new OpenLayers.Layer.Vector("isoline", {
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: "../aramus_data/vector/gml/isoipse_2498.gml",

   })
});

Re: [OpenLayers-Users] Control outside map

[bartvde]

Hi,

if you look at GeoExt actions you can see a way to do this (i.e. the
concept could be usable):

http://svn.geoext.org/core/trunk/geoext/lib/GeoExt/widgets/Action.js

Best regards,
Bart

Re: [OpenLayers-Users] getFeatureCount function?

[bartvde]

Hi,

you need to listen to the loadend event of the layer, and then check the
number of features.

layer.events.register("loadend", layer, function() {
alert(this.features.length); });

Best regards,
Bart

Re: [OpenLayers-Users] How to get only attributes from WMS or WFS in Openlayers

[bartvde]

Hi,

you can specify propertyNames on the options when you call
OpenLayers.Format.WFST write to only get a list of attributes back.

See also:
http://trac.openlayers.org/ticket/1827

I use a WFS DescribeFeatureType request to get the list of attributes and
then I filter out the geometry attribute so that I don't need to hardcode
the list of attributes.

Hi,

how is your map instantiated? With a fixed set of scales/resolutions?

Or are you using fractionalZoom: true in your map config?

Re: [OpenLayers-Users] Doubt with SOSCapabilities

[bartvde]

Ok, I get what you mean now.

However, I can not deduct from the GetCapabilities response that DISTANCE
is only applicable for that feature of interest.

What interface (request) does a SOS have to get that information
programmatically? If you do not know, maybe you can ask on the 52N list.

But currently this is not possible using the OpenLayers SOS client,
however if you find out exactly how to implement this, and open up a bug
in the OpenLayers Trac, I am willing to have a look at implementing it.

TIA.

Bart

Re: [OpenLayers-Users] Doubt with SOSCapabilities

[bartvde]

Hi,

not sure I really get your question, can you elaborate a bit? Is this
something you can read from the GetCapabilities, or the info needs to be
retrieved through a request on the SOS? If so, which request, and do you
have an example XML request?

If I understand things correctly, in the example SOS used one feature of
interest has exactly one procedure, and they have the same id.

Is your SOS structure different, and if so, can you post your SOS's
GetCapabilities response using something like pastebin? TIA.

Re: [OpenLayers-Users] Write a KML file in proper projection.

Right, it's as simple as that.

Although for proj4js I use a custom build with the projections I use in my
application compiled into the javascript build.

Proj4js by default will get definitions from spatialreference.org.

Right, you need to use proj4js since you have a custom projection
(ESPG:25832) which is not supported by OL out of the box.

Define internalProjection and externalProjection on your format:

/**

 * {} When passed a externalProjection and
 * internalProjection, the format will reproject the geometries it
 * reads or writes. The externalProjection is the projection used by
 * the content which is passed into read or which comes out of write.
 * In order to reproject, a projection transformation function for
the
 * specified projections must be available. This support may be
 * provided via proj4js or via a custom transformation function. See
 * {} for more information on
 * custom transformations.
 */
externalProjection: null,

/**
 * APIProperty: internalProjection
 * {} When passed a externalProjection and
 * internalProjection, the format will reproject the geometries it
 * reads or writes. The internalProjection is the projection used by
 * the geometries which are returned by read or which are passed into

Re: [OpenLayers-Users] WFS Layer / Vector Layer

[bartvde]

Hi Andrew,

nope, only POST is supported. Why would you want GET? I had this
discussion with Tim Schaub in the past and I could not think of a good
reason why I wanted GET if POST also works for the WFS product. Maybe you
have a good reason though?

Best regards,
Bart

Re: [OpenLayers-Users] WFS Layer / Vector Layer

[bartvde]

Hi,

don't use the namespace prefix in the featuretype.

{
url:  "/MyApp/Proxy.ashx",
featureType: "boundary",
featurePrefix: "mystore",
version: "1.1.0"
})

If this does not work, try specifying the featureNS (so the corresponding
URI) explicityl.

Bart

Sure WFS-T can be used to update attributes only.

The only thing I've run into when implementing is:

Re: [OpenLayers-Users] SplitFeature question

I think you can use the beforesplit event for this (and use the source
property):

 * Supported control event types (in addition to those from

 * beforesplit - Triggered before a split occurs.  Listeners receive an
 * event object with *source* and *target* properties.

Re: [OpenLayers-Users] inconsistent click handling

[bartvde]

Hi,

my first guess would be the clickTolerance, try setting it to a larger
value (defaults to 4).

There is only an ugly prototype way to set it right now, but please give
it a try:

OpenLayers.Handler.Feature.prototype.clickTolerance = 6;

What type is your base layer? WMS?

If  so, you can use allOverlays: true on your MAP object.

Options are the 4th parameter of the constructor, so use:

 {
 layers: 'basic',

 displayInLayerSwitcher: false,

Hi,

I don't know exactly at what hour the nightly build runs, but it will be

Ofcourse you can always apply patches yourself, use the patch utility.

Re: [OpenLayers-Users] WFS layer not display..

[bartvde]

featureType is without the namespace prefix, so city_point.

Re: [OpenLayers-Users] WMSCapabilities parse problem

Hi,

I think you need to use a proxy in between.

Re: [OpenLayers-Users] WMSCapabilities parse problem

[bartvde]

Hi,

you don't need Format.XML in between but I doubt that's your problem.

var CAPformat = new OpenLayers.Format.WMSCapabilities();
var cap = CAPformat.read(response.responseXML || response.responseText);

Can you share the output of your WMS GetCapabilities response?

Bart

set displayInLayerSwitcher to false on your single base layer to only show

Re: [OpenLayers-Users] Multiple invoke by zoom, very bad performance

[bartvde]

Does this happen with normal zoom or with the mousewheel zoom?

If with the mousehweel zoom, check the new options (in OL trunk) for the
MouseWheel handler:

/**
 * Property: interval
 * {Integer} In order to increase server performance, an interval (in
 * milliseconds) can be set to reduce the number of up/down events
 * called. If set, a new up/down event will not be set until the
 * interval has passed.
 * Defaults to 0, meaning no interval.
 */
interval: 0,

/**
 * Property: delta
 * {Integer} When interval is set, delta collects the mousewheel z-deltas
 * of the events that occur within the interval.
 *  See also the cumulative option
 */
delta: 0,

/**
 * Property: cumulative
 * {Boolean} When interval is set: true to collect all the mousewheel
 * z-deltas, false to only record the delta direction (positive or
 * negative)
 */
cumulative: true,

Re: [OpenLayers-Users] Overview map with ArcIMS breaks

[bartvde]

Hi Vadim,

I just tried and I can reproduce your problem. Normally these issues can
be fixed by cloning the baselayer, however for the ArcIMS case this did
not work for me, probably since it misses a specific implementation of the
clone method.

However, using a nother separate ArcIMS layer for the overview map control
works okay. I know it's a workaround for the problems you encountered, but
hopefully it will keep you moving.

layer = new OpenLayers.Layer.ArcIMS( "Global Sample Map",

"http://sample.avencia.com/servlet/com.esri.esrimap.Esrimap";,
options );

var overview = new OpenLayers.Layer.ArcIMS( "overview",

"http://sample.avencia.com/servlet/com.esri.esrimap.Esrimap";,
options );

map.addLayer(layer);

map.addControl (new OpenLayers.Control.OverviewMap({layers:
[overview]}) );

Bart

OpenLayers.Control.Panel has an activateControl method, so if you put your

Re: [OpenLayers-Users] Cursor style on control activation

Alexandre,

that should not be necessary, css is all that it takes.

IIRC the syntax is:

.olControlZoomBoxActive {
  cursor: pointer;
}

etc. so displayClass plus Active.

Re: [OpenLayers-Users] Problem in openlayers when migrating from Mapserver 5.0 to 5.2

[bartvde]

Hi,

did you try and leave out the parameter mode like I said in my first e-mail?

It looks like every tile retrieves a full map, because you use mode=map in
your parameter list. Remove it, so use:

countrylayer  = new OpenLayers.Layer.WMS( "Country Outline",
  "http://"; + server + "/cgi-bin/mapserv.exe?",
  {map:'../htdocs/ms/stats.map', layers: 'cntry98', format: "image/png"},
  country_options);

Re: [OpenLayers-Users] Problem in openlayers when migrating from Mapserver 5.0 to 5.2

[bartvde]

What do you mean with repeating as tiles? Can you show an example, a
screendump of what is wrong?

Also, your WMS layer should not get the parameters mode and layers, remove
them from your Layer.WMS definition.

Bart

Re: [OpenLayers-Users] my vector layer doesn't display

[bartvde]

Whether or not it's a must, depends on what your WFS server advertizes in
the xmlns part (on the root element) of the GML response. It must match
exactly.

Hi,

why don't you set:

OpenLayers.ProxyHost = 'test.aspx?param=';

and then you don't need to change anything inside of the OpenLayers library.

No this is not possible currently, you would need to implement write

Re: [OpenLayers-Users] mergeNewParams not working

[bartvde]

You should apply it to the polygon layer.

What WMS are you using? Mapserver? Try to put your SLD XML on a webserver
and reference it with the SLD parameter without the use of OpenLayers in
between. If this does not work, you might have better luck asking on the
mailing list of your server product.

Have you tried without the xsl stuff embedded in your XML?

Also, things like PropertyIsEqualTo etc need to be in the ogc prefix, not
sure if this is the problem though (some WMS-s are quite permissive).

Bart

Re: [OpenLayers-Users] loading panel update

[bartvde]

Hi Max,

thanks for your feedback, I've fixed this up [1] by giving the css class a
display:none to start with, so it only shows when a loadstart event is
actually coming in, and like you said the Google layer does not support
the load events currently.

[1] http://trac.openlayers.org/changeset/9749

Best regards,
Bart

Hi bartvde,

I found another Problem with the "Loading-Panel".
If you add the LoadingPanel to a map which consists only of Google layer the
Loadingpanel appears but did not disappear when the layer are loaded.
I know that the reason is that Googlelayer didnt fire a loadend event.

I solved the Problem for me by editing the draw function of the loading
panel where i set the display style to 'none'.
My drawfunction now looks like this:

draw : function() {
OpenLayers.Control.prototype.draw.apply(this, arguments);
this.div.style.display = "none";
return this.div;
},

Is there a better way for solving this Problem?
I need this solution because in our application it is possible to add and
remove WMS layer.

With kind regards
Max Weidemann

[OpenLayers-Users] loading panel update

[bartvde]

Recently a few issues have been reported with the loading panel addin,
e.g. not being able to use the mousewheel zoom when the loading panel is
visible, and not being able to click a marker. This was all caused by the
loading panel div having the same size as the map. I've modified the
loading panel code [1] so that the div size is only the size of the
animated gif (update to the css class), which should minimize problems.
Ofcourse there will still be issues when somebody is exactly on top of the
animated gif, but chances are much less that this will lead to problems.

Please try out the code (svn update from 
http://svn.openlayers.org/addins/loadingPanel/trunk/) and report any
issues. TIA.

Re: [OpenLayers-Users] Event/Msg when all LayerPics are loaded?

[bartvde]

There is the loadend event on a per layer basis.

There is also the addin called LoadingPanel which automates this for you.

Re: [OpenLayers-Users] Catching WMS Exceptions

[bartvde]

Hi,

I don't think you can currently. You can use onerror of the img, but it
won't give you the contents.

A way would be loading the images through AJAX, which has disadvantages as
well (same origin policy and needs changes to OpenLayers).

Maybe the new WMS POST layer has a facility for this, but I don't know if
your WMS service supports POST?

Re: [OpenLayers-Users] Convert Coordinates EPSG:4326 to 31466 doesn?t work ??

[bartvde]

I think you need to add the right towgs84 parameters to your projection
definition.

For Dutch national grid I use (I added the towgs84 params):
Proj4js.defs["EPSG:28992"] = "+proj=sterea +lat_0=52.156160
+lon_0=5.387639 +k=0.079 +x_0=155000 +y_0=463000 +ellps=bessel
+units=m
+towgs84=565.2369,50.0087,465.658,-0.406857330322398,0.350732676542563,-1.8703473836068,4.0812
+no_defs ";

Google [1] or check the EPSG database for the right towgs84 settings for
your projection.

Re: [OpenLayers-Users] transparent param not sent to WMS service

[bartvde]

Hi,

you should use:

 var CTISwms = new OpenLayers.Layer.WMS( "CTI-S WMS",
 "http://wms.sst-sw.rncan.gc.ca/wms/toporama_en";,
 {layers: 'railway_30m', format: 'image/png', transparent: true},
 {isBaseLayer: false, visibility: true,
 transitionEffect: 'resize'});

Please not the 3rd parameter is the layer parameters, which are sent to
the server. The 4rd parameter is the layer options.

Best regards,
Bart

Re: [OpenLayers-Users] Layer from GML loading only for the first time

Hi,

you are probably running into browser cache. So either change the cache
settings on your webserver for the XML1 subdir (tell the browser to never
cache the file), or append a random number to the url.

Re: [OpenLayers-Users] GML Format and IE7

[bartvde]

Hi,

can you provide a bit of context for your code fragment (what type of
layer are you using)? Post a bit more code.

formatOptions is not the same as style options. Format is for reading XML
data, and has nothing to do with styling.

Re: [OpenLayers-Users] Problem with a WFS request

[bartvde]

Hi Arthur,

check out the console tab of Firebug, and make sure XMLHttp requests are
on (check out options on the right in Firebug).

It's because OpenLayers uses POST by default for WFS, so that's why you
don't see any parameters. You will see the POST body though in Firebug.

Best regards,
Bart

Re: [OpenLayers-Users] Problem with a WFS request

[bartvde]

Your GML looks okay to me. You don't have any attributes (next to the
geometry), but that should be no problem.

Can you see the request go off with Firebug at all when adding the vector
layer to your map? Are you using a proxy in between or is the traffic
local?

Bart

 Hi Arthur,

 yes the BBOX strategy will take care of that.

 The GML version is determined by the protocol version, WFS 1.0 is tied
 to
 GML2, whereas WFS 1.1 is tied to GML3. The WFS protocol version
 defaults
 to 1.0, so you will get the Format.GML.v2 parser. So you should not
 need
 to change anything.

 You can retrieve the url for featureNS from a WFS DescribeFeatureType
 request (intranet url, for example only):

 http://test.intranet.rijkswaterstaat.nl/services/geoservices/overzichtskaartnl?service=WFS&request=DescribeFeatureType&version=1.0.0

 then check the source and look for targetNamespace, by default this is
 http://mapserver.gis.umn.edu/mapserver

Re: [OpenLayers-Users] Problem with a WFS request

Hi,

is there any prefix used in your GML, again Mapserver defaults to ms:, so
in that case you need to add:

featureType: "aster_gdem",
featureNS: "http://mapserver.gis.umn.edu/mapserver";,
featurePrefix: "ms"

Re: [OpenLayers-Users] openlayers + mapserver + query parameters ??

Hi,

it should work, if you pass in the necessary additonal url parameters
(check the Mapserver CGI interface for details), try something like:

new OpenLayers.Layer.MapServer( "xxx", url, {layers: 'basic', mode:
'itemquery', anotherparam: 'bla'}, {singleTile: true} );

The MapFish PrintProtocol is the communication layer you can use. But it

IIRC OpenLayers does not read the boundedBy of the whole

GML.v2.

Re: [OpenLayers-Users] GetFeatureInfo in OpenLayers with no proxy?

[bartvde]

You should be able to do without the proxy in that specific case.

What I did for one website was switch the WMS version to 1.0.7 in the
GetFeatureInfo requests, so that there were no OGC mimetypes and the
response was still plain old XML (mimetype wise). I was using Mapserver
for that site though, not sure what you are using.

Best regards,
Bart

Re: [OpenLayers-Users] Events on text labels

Hi Tamlyn,

Re: [OpenLayers-Users] mr. OL, don't create the hidden layer tiles, please!

[bartvde]

Hi,

you should not use setVisibility on baselayers. Always use setBaseLayer on
the map.

Re: [OpenLayers-Users] Support for Cursors?

[bartvde]

Hi Bill,

yes it's in 2.8.

You need to add css classes depending on the displayClass + "Active"
 of a control, e.g. this is what I have:

.olControlDragPanActive {
cursor: url(lib/openlayers/theme/default/img/pan.cur) 16 16,
url(../geoservices2.2/lib/openlayers/theme/default/img/pan.cur), auto;
}
.olControlZoomBoxActive {
cursor: url(lib/openlayers/theme/default/img/zoomin.cur) 9 9,
url(../geoservices2.2/lib/openlayers/theme/default/img/zoomin.cur),
auto;
}
.zoomoutActive {
cursor: url(lib/openlayers/theme/default/img/zoomout.cur) 9 9,
url(../geoservices2.2/lib/openlayers/theme/default/img/zoomout.cur),
auto;
}
.olControlDragPanActive.olDragDown {
cursor: url(lib/openlayers/theme/default/img/pandown.cur) 16 16,
url(../geoservices2.2/lib/openlayers/theme/default/img/pandown.cur),
auto;
}
.GeoServicesControlSLDSelectActive {
cursor: default;
}
.GeoServicesControlFeatureInfoActive {
cursor: pointer;
}
.olControlMeasureActive {
cursor: crosshair;
}
.olControlDrawFeaturePolygonActive {
cursor: crosshair;
}
.olControlDrawFeaturePointActive {
cursor: crosshair;
}
.olControlDrawFeaturePathActive {
cursor: crosshair;
}
.olControlDrawFeaturePointActive {
cursor: crosshair;
}
.olControlDrawFeaturePathActive {
cursor: crosshair;
}
.olControlDrawFeaturePolygonActive {
cursor: crosshair;
}

Hope this helps.

Best regards,
Bart
