Many proposals have been made for how to do this . . . → Read More: Do we need to encode location in news feeds? As the Geo-Web comes into being it will present many new kinds of services both for the traveller and the stay at home. Some of these will be familiar to us from the pre-tech days (e.g. travellogues), and some will . . . → Read More: gMedia – Towards Geographically Aware Media Readers of this BLOG will realize that it is part philosophy, part hard core tech, and part GML tutorial. Since we have been slogging through a fair bit of the technology it is time for more of the philosophy. Those . . . → Read More: Where are we going? This note contains a sample style sheet (XSLT) that styles GML for visual presentation in Google Earth's browser. The style sheet can be examined by clicking on MORE below. A sample KML generated by styling dynamic GML data is shown below (click MORE). This is described in the note Styling GML to KML Using XSLT. A sample GML data file is shown below (click MORE). This is described in the note on Styling GML to KML with XSLT. The full XSLT and KML output file will be posted as soon as BLOG.COM's HTML editor co-operates. This note provides a simple example of styling GML data (obtained from a Web Feature Service) to KML. KML is used in this case as a graphics output language like SVG and the Google Earth Browser can be thought of . . . → Read More: Styling GML to KML – XSLT Attached is a sample Simple Geometry Profile from GML. This contains simple geometries including Point, LineString, and Polygon. |
