Hi, They use a file called world_borders.js This file contains a geoJSON with the world borders but also information about statistics.
1. When the main file is loaded, they create a new map with options 2. They add a google layer to the map. 3. They create a new style and context 4. They create a vector layer with the precedent style and a geoJSON parser. 5. They add the geojson to the parser and the parse is passed to the layer. 6. Finally, they add a control used for the select_feature event. The style and the context are used to define the color of the country Hope this will be useful, Jérome Timmie wrote: > > Hello, > > I found a exciting map here: > Open Source Activity Map - > http://www.redhat.com/about/where-is-open-source/activity/ > > Can you help me to understand how they load the statistical data? > It is done within the world_borders layer by GeoJSON fromat. > > But where and how to they get the file? > > Thanks in advance, > Timmie > -- View this message in context: http://n2.nabble.com/please-help-to-understand-loading-of-existing-geojson-layers-tp2692284p2722030.html Sent from the OpenLayers Users mailing list archive at Nabble.com. _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
