We’ve officially wrapped up the OpenLayers Mobile code sprint. This week has brought a very welcome infusion of energy to the project. I think it is safe to say that all involved have felt we have achieved the goals we set out for ourselves at the start of the week. In addition to significantly enhancing [...]

Day four already!? Not sure what happened to day three (perhaps we all forgot to sleep). After picking off the easy wins at the start of the week, we’ve spent the past two days wrestling with some of the tougher issues that come up when you target a broad array of devices in an area [...]

We’ve wrapped up our second day in Lausanne, making good progress on a number of fronts. Our examples have always been the richest source of learning material for OpenLayers newcomers. The example search page got a well deserved overhaul today – making it more convenient to find relevant code samples. In addition to the nicer [...]

A solid group of OpenLayers developers and power users have gathered in Lausanne to bring OpenLayers into the mobile age. Today (and yesterday) we spent some time getting organized and laying the groundwork for the week ahead. Each of our examples got a nice, mobile friendly layout thanks to Antoine Abt (resize your browser with [...]

When using rule based styling or constructing queries for features, application developers often hand-code their filters. For example, if you wanted to style or select a subset of US State features that started with the letters B through O, you might create a filter that looked like this: var filter = new OpenLayers.Filter.Logical({ type: OpenLayers.Filter.Logical.AND, [...]

As of today, OpenLayers has a new layer type: OpenLayers.Layer.Bing. “Why that” you may ask, “there is OpenLayers.Layer.VirtualEarth already”. So why is this new layer type so special? It is the first time that we access tiles from a commercial service directly. Others (e.g. Google Maps) do not provide direct access to their tiles, but [...]

As of today, the OpenLayers development version supports Google layers served by the Google Maps V3 API. This is not only Google’s latest and greatest Maps API, it also makes life easier on the OpenLayers side because no API key is required. To use the new Google layer, application developers just have to include this [...]

The OGC recently ratified the Web Map Tile Service Implementation Standard (WMTS) and OpenLayers followed up with a WMTS layer and capability parsing support. The layer supports both the “RESTful” and “KVP” request encoding (terms from spec), and the capabilities parser greatly helps in creating layers with the correct properties. There are several tickets with [...]

OpenLayers owes much of its functionality to sandbox innovations in the repository.  At the FOSS4G conference in Sydney, I played a short animation representing commit activity in the OpenLayers trunk.  As a way of acknowledging all of the great work done by sandbox developers, I wanted to post a similar animation that shows sandbox commits [...]

Several OpenLayers developers and volunteers gathered after the FOSS4G conference to participate in the Saturday code sprint. And guess what: a lot was accomplished! Here is a quick overview: Mike Adair (DM Solutions) and Julien Lacroix (Mapgears) finished Mike’s work on a graticule control, which also brings label positioning and a utility function to format [...]
