We’ve put together another release of the GeoExplorer application built with GeoExt.  This release includes some great new features that let you explore WMS layers from multiple sources and publish your results as an embedded map in any web page.

The updated “available layers” dialog allows you to choose from a list of currently configured sources or add your own.

Add Layers Dialog

In this case, I’ve decided to create a simple map showing fire locations and current weather conditions in the US.  For the fire locations, I added the Firefly service from the Geography Department at the University of Maryland.  To get a sense for current weather conditions nationwide, I added radar reflectivity data from Iowa State University Department of Agronomy.

Clicking on the publish button launches a new dialog for configuring the map export.  The result is an HTML snippet that I can include in any web page – like this one:

You can download the application archive to set it up on your own server, or try out the demo we’ve put up.

  1. Hello,

    I’m curious if there is an easy way to extend the number of zoom levels available in GeoExplorer… I need to be able to zoom in beyond Zoom Level 15 (1:13517). Thanks!

    1. Unfortunately, there is not a way to easily configure resolution related parameters in this version of the application.

      In GeoExt, the WMSCapabilitiesReader creates layers with the OpenLayers defaults essentially. In the next release of GeoExt, we’ll likely have support for user supplied layer options on that reader. This would allow applications to have configuration options for resolution (and projection) information.

    1. You’d have to dive into the code a bit to wedge Google Maps into this version of GeoExplorer. We’ve continued development of this application for a few specific products and have begun making it a plugin based viewer.

      As this work stabilizes, we’ll push what we can to GeoExt. This plugin based viewer will allow people to provide layer source plugins of any type. We’ve implemented Google Maps and WMS layer source plugins initially. I imagine it will be 6 months or so before this work could make it into GeoExt.
