I'm looking to use SMW to visualise georeferenced data. Specifically, I'm using the 'External Data' extension to get temperatures, wind speeds, etc from a database of weather observations. These are all associated with a latitude and longitude. All of this information is available as semantic properties. This means that, 1. I can plot the observation point on a map, or 2. I can make a table of the data All very nice, but could be improved... Question - is there a way to mark a series of points on a map and change the icon colour according to the value of a numerical property at that point? Thanks!

Have a look at the 'Exhibit' Semantic Result Format (http://www.mediawiki.org/wiki/Extension:Semantic_Result_Formats/exhibit_format). I do something similar using a modified 'Exhibit' code with multi-valued properties where one part is the value, another part the lat/lon coordinate and other parts are extra infos. In my case either the sizes of the icons or their color are determined by the 'value' part of the property shown at the lat/lon position.

Hi Andy, Another alternative is to use the Semantic Compound Queries extension: http://www.mediawiki.org/wiki/Extension:Semantic_Compound_Queries You can see an example of the kind of use you're talking about here: http://smw.referata.com/wiki/Main_Page -Yaron 2010/10/30 Günther Zehetner <zeh...@mo...>: > Have a look at the 'Exhibit' Semantic Result Format (http://www.mediawiki.org/wiki/Extension:Semantic_Result_Formats/exhibit_format). > I do something similar using a modified 'Exhibit' code with multi-valued properties where one part is the value, another part the lat/lon coordinate and other parts are extra infos.
