Subject: [OpenLayers-Dev] Cross-domain problem with a external vector layer
 in format GeoJSON or GeoJSONP
Message-ID: <509A6FDA.8010300@upm.es>

Dear all,

I'm trying to add a dinamic layer of earthquakes over a tiled WMS layer.
Feeds of earthquakes are provided by USGS 
(http://earthquake.usgs.gov/earthquakes/feed/) in different formats 
included GeoJSON and GeoJSONP.

I have included next Jscript to add the vector layer

             var vector_layer = new OpenLayers.Layer.Vector("GeoJSON", {
                 projection: "EPSG:4326",
                 strategies: [new OpenLayers.Strategy.Fixed()],
                 protocol: new OpenLayers.Protocol.HTTP({
                     url: 
"http://earthquake.usgs.gov/earthquakes/feed/geojson/2.5/day",
                     format: new OpenLayers.Format.GeoJSON({ 
ignoreExtraDims: true })
                 })
             });
             map.addLayer(vector_layer);

But none of the browsers (IE, FireFox or Chrome) shows the points of the 
earthquakes.

Can any one help me, please?

Best regards,
Miguel A. Manso

Hi,

this question would be better suited for the openlayers-users list. If
your layer is available in GeoJSONP format, you will want to use
OpenLayers.Strategy.Script instead of OpenLayers.Strategy.Fixed. See
http://openlayers.org/dev/examples/cross-origin.html for an example.

Andreas.

Subject: [OpenLayers-Dev] WMTS GetCap bug?
Message-ID: <CAPitpCZafnuGr8GyCqNXax8-+p1hzQ=Z_KBtE0yV0Hx5pve+CQ@mail.gmail.com>

Hello All,

In combination with RD Hales we have come across something slightly
strange, and were wondering if it was a change you were aware of.

Basically, a wmts getCapabilities doc from a Geoserver v2.2 no longer has
the <style> tag per layer, and so when creating a layer in OpenLayers using
the getCapabilities document it will fail every time because in the
createLayer: function(capabilities, config)

the style loop will always return null, and so the layer creation will call
style: style.dentifier, which will be undefined.

A getCap for WMTS in a 2.1.4 geoserver still does have that style tag.


Is this a configurable option now?

Regards,

Toby

We have recently implemented isPointInStroke(x,y) in Firefox (
https://bugzilla.mozilla.org/show_bug.cgi?id=803124).
This is a parallel to isPointInPath(x,y) and returns true if the point is
inside the area contained by the stroking of a path.
It was easily implemented on top of Direct2D, Cairo, Skia, and CoreGraphics
and shouldn't be difficult for other systems.

We implemented this to help support functionality needed for shumway (flash
on html)

Hi,

I am new to OpenLayers and looking for a quick start to add a new
feature/layer on existing application.

I see there are bunch of JS files. any link or brief description will be
great.

Thanks a lot

Firstly, this belongs on the openlayers-users list - it is not about 
development of openlayers.

Your best start is look through the examples on the openlayer website to 
get a feel for the code. In your own code, you are looking for the 
map.addlayer or map.addlayers methods. To add a new layer, you probably 
want to add an extra one of these into the code with the appropriate set up.

Subject: [OpenLayers-Dev] OpenLayers, using SLD for WMS
Message-ID: <CAE4htmOgKCY8YrQi0+BPEA71Z7qeVpBnx4tkidR=8rWqv3tDyw@mail.gmail.com>

Hello,

I have two versions of the personal project I'm working on:

http://myowngis.com/index2.html
http://myowngis.com/index.html

Both are very simple integrations with a WMS server.

In the first example, I have tried to apply an SLD to style the hydrography
layer, but when I do, the fill disappears.  I have tried to apply a
PolygonSymbolizer to this, but then I receive an error that I can only
apply a polygon definition to a polygon layer.

I understand that the hydrography layer is a line type layer, which is why
it won't allow me to apply the polygon style.  But if that is the case,
where is the blue fill colour coming from on the default style?

Any help would be appreciated.

Regards,
Chris

Hi Everyone,

I was trying to parse a query with "Function" in it with
OpenLayers.Format.Filter.v1 read() function. Write()  works fine but read()
fails and the reason is that in v1 readers.ogc["Function"] function is not
implemented Have a look at  line 213:

https://github.com/openlayers/openlayers/blob/master/lib/OpenLayers/Format/Filter/v1.js

Are there any plans to complete this functionality at some stage?

Thanks Alex

Subject: [OpenLayers-Dev] removeComponent from LinearRing seems to remove
	too much points
Message-ID: <1354097100683-5019251.post@n6.nabble.com>

Hi,
yesterday I stumbled over a problem while writing a function to remove
points from geometries. When I want to remove a point from a LinearRing that
I created with 3 points (the ring will automatically have 4 points to be
closed) I can remove one of them because of the conditions in
OpenLayers.Geometry.LinearRing. Afterwards the LinearRing only consists of 2
individual points (actual 3) and is no longer a ring.

LinearRing states at the moment:

removeComponent: function(point) {
        var removed = this.components && (this.components.length > 3);
        if (removed) {
...

But it must be:

removeComponent: function(point) {
        var removed = this.components && (this.components.length > 3);
        if (removed) {
...

Also there seems to be a bug in the way what is returned by
OpenLayers.Geometry.Collection.removeComponent. It doesn't not really return
if a component existed in that Collection and could really me removed. It
just returns true.

But when it is written like this it returns the correct boolean:
removeComponent: function(component) {
var length = this.components.length;
    OpenLayers.Util.removeItem(this.components, component);

    if (length != this.components.length) {
        // clearBounds() so that it gets recalculated on the next call
        // to this.getBounds();
        this.clearBounds();
        return true;
    }
    return false;
},

I hope you can follow me, if wanted I can create tickets and patch files.
Providing that everything I have written is correct.

So the following (jasmine-1.2.0 test) should be correct, at the moment it
wouldn't work.

describe("OpenLayers.Geometry.LinearRing.removeComponent", function() {
    it("3 point ring", function() {
        var point1 = new OpenLayers.Geometry.Point(1.0, 1.0);
        var point2 = new OpenLayers.Geometry.Point(1.0, 2.0);
        var point3 = new OpenLayers.Geometry.Point(2.0, 2.0);
        var ring = new OpenLayers.Geometry.LinearRing([ point1, point2,
point3 ]);
        var clone = ring.clone();
        expect(clone.equals(ring)).toBe(true);

        var removed = clone.removeComponent(clone.components[0]);
        expect(removed).toBe(false);
        expect(clone.equals(ring)).toBe(true);
    });
    it("4 point ring", function() {
        var point1 = new OpenLayers.Geometry.Point(1.0, 1.0);
        var point2 = new OpenLayers.Geometry.Point(1.0, 2.0);
        var point3 = new OpenLayers.Geometry.Point(2.0, 2.0);
        var point4 = new OpenLayers.Geometry.Point(2.0, 1.0);
        var ring = new OpenLayers.Geometry.LinearRing([ point1, point2,
point3, point4 ]);
        var clone = ring.clone();
        expect(clone.equals(ring)).toBe(true);

        var expectedResult = new OpenLayers.Geometry.LinearRing([ point2,
point3, point4 ]);
        expect(clone.equals(expectedResult)).toBe(false);

        var removed = clone.removeComponent(clone.components[0]);
        expect(removed).toBe(true);
        expect(clone.equals(ring)).toBe(false);
        expect(clone.equals(expectedResult)).toBe(true);
    });
    it("remove non existend point", function() {
        var point1 = new OpenLayers.Geometry.Point(1.0, 1.0);
        var point2 = new OpenLayers.Geometry.Point(1.0, 2.0);
        var point3 = new OpenLayers.Geometry.Point(2.0, 2.0);
        var point4 = new OpenLayers.Geometry.Point(2.0, 1.0);
        var ring = new OpenLayers.Geometry.LinearRing([ point1, point2,
point3, point4 ]);
        var clone = ring.clone();
        expect(clone.equals(ring)).toBe(true);

        var removed = clone.removeComponent(new
OpenLayers.Geometry.Point(7.0, 7.0));
        expect(removed).toBe(false);
        expect(clone.equals(ring)).toBe(true);
    });
});

the correction in LinearRing should of course be:
removeComponent: function(point) {
        var removed = this.components && (this.components.length > 4);
        if (removed) {
...
