[OpenLayers-Users] WMS overlay not shown at zoom level 0 when singleTile: true

Hi all, In the attached code, the WMS overlay is shown fine at zoom level 1, but at zoom level 0, it disappears. If I either remove the singleTile: true option, or use a MetaCarta base layer instead of the Google one, then the overlay shows up fine at zoom level 0. I took a look at the WMS

Re: [OpenLayers-Users] WMS overlay not shown at zoom level 0 when singleTile: true

Thanks, Chris, that makes sense. Is there a common workaround for this? -- View this message in context: http://n2.nabble.com/WMS-overlay-not-shown-at-zoom-level-0-when-singleTile-true-tp4508945p4509041.html Sent from the OpenLayers Users mailing list archive at Nabble.com.

[OpenLayers-Users] Interface for associating SLD styles with feature types

Hi all, I've asked this on the GeoServer forum, but haven't gotten any responses, so I thought I might try it here. It's not exactly OpenLayers-specific, but it concerns matters that other OL users may be familiar with/interested in. We're using GeoServer to serve up a large set of features,

Re: [OpenLayers-Users] Canceling a currently loading WMS layer

Hi Andreas, Great, thanks. In case anyone else is trying to do this, I needed to call .destroy() on the layer for this to work (not sure if that's clear from the changeset). Just calling map.removeLayer() resulted in HTTP requests for WMS images continuing to be made after the layer was

[OpenLayers-Users] Canceling a currently loading WMS layer

Hi, This thread suggested that there wasn't an elegant way to do this: http://openlayers.org/pipermail/dev/2008-March/002665.html Simply removing a layer still leaves some processing continuing in the background. Has anyone found a method to completely stop a currently loading layer since that

[OpenLayers-Users] Spatial constraints of a WFS GetFeature request

Hi all, I'm trying to allows users to click on a WMS overlay and get a popup showing a list of features at the location they clicked. It's a setup similar to http://trac.openlayers.org/wiki/GetFeatureInfo, but instead of a WMS GetFeatureInfo request, I'm using WFS GetFeature, since it allows me

Re: [OpenLayers-Users] Spatial constraints of a WFS GetFeature request

Hi Andreas, Thanks for the help. I should've mentioned that the map also has features that are points, and GetFeatureInfo's tolerance wasn't quite wide enough for how we are displaying them; that was the big impetus for using GetFeature. Additionally, the user will be dynamically adding and

Re: [OpenLayers-Users] Vector-like feature interaction with large, complex layers

Thanks, Ian; hm, many of the polygons we're using are adjoining, like counties, and my guess is that generalizing them would make their borders a bit messy, and it might be a bit of work to try it out. I'll ask our GeoServer/OL support person what he thinks about it, though. Any other ideas for

[OpenLayers-Users] Vector-like feature interaction with large, complex layers

Hi all, I've read about a couple of methods (clustering strategy, choosing WFS or WMS based on zoom level) for working around the issue of WFS layers being unusable for performance reasons when large numbers of complex features are involved. Neither of these are terribly good solutions for our

[OpenLayers-Users] Units of BBOX in a WMS request

Hi, I'm making WMS requests to GeoServer, with the map and layer options listed below, but the BBOX values in the requests are sent in degrees, instead of meters. I'm a bit new to OpenLayers and feel like I might be missing something simple. In case it's relevant, the .units property of both

[OpenLayers-Users] Saving with a Google Maps base layer

Hi, I'm trying to give users the option of saving/printing a map, and I'm currently working off the tile stitching code to create a composite image of the map's layers: http://trac.openlayers.org/wiki/Printing Since the OpenLayers.Layer.Google class doesn't have a grid property, the Google Maps

Great, this sounds promising, at the very least. Many thanks for all the input on this; Gregor, definitely let us know how it goes if you're able to swing the development on it. This seems like something that might be of interest to many folks. Thanks, Tom Christopher Schmidt-2 wrote: On

[OpenLayers-Users] GetFeatureInfo always returns no features were found

I'm using this code to get information on a feature via WMS: http://trac.openlayers.org/wiki/GetFeatureInfo However, I always get no features were found as the response. I used Firebug to get a request URL and used the SRS and BBOX values to make a GetMap request, which showed the correct
