Abstract: Scalable Vector Graphics (SVG) format is in develo pment since 1998 by W3C SVG working group. Its specification based on XML grammar makes it excellent, scalable tool for interactive WebGIS creation. SVG code can be easily combined with several web standards (CSS, XSL) and run on resource-limited devices. Several rendering meth ods like filtering, gradients and animation are included in specification, but not all of them are supported by web browsers. The paper describes practical issues of SVG implementation for web pres entation of hydrometeorological data. Rendering of text and graphical elements for presentation of spatial data from automatic monitoring system were tested on leading web browser (Internet Explorer, M ozilla Firefox and Opera). To archive good scalability of web application, SVG embedment in XHTML code was of main concern, not SVG standalone approach. Several methods of embedded SVG image rendering were tested - tag, tag and tag. Some of the presented methods are not recommended, but still in use and working. Native implementation of SVG by web browser in the year 2007 still is far from perfection. None of them ensures full SVG embedded support, but significant progress in recent years should be stated.
