Abstract

We have developed a prototype web service that brings the wealth of Virtual Observatory image data to the Google Sky desktop client. The web service, "KML Now!," presents the user with a simple web interface and requires no specialized knowledge of image conversion, coordinate system conversion, or Google Sky's KML metadata format. KML Now! makes use of Virtual Observatory Simple Image Access Services to acquire images based on user-input search coordinates. Once images are acquired, open source conversion software is used to generate Sky-compatible image and metadata files; the files are cached on the server for reuse. A "launcher" KML file pointing to all applicable server-side data is returned to the user, and when opened in Google Sky, all images are automatically placed within the desktop client. KML Now! can also operate directly on a user-specified image, without the need for Virtual Observatory interaction. A KML Now! query is coded in URL arguments, which allows it to be easily called from within Google Sky, a feature to be added in future developments. Funding for this project is provided by the National Radio Astronomy Observatory and the National Virtual Observatory, both supported by the National Science Foundation.
