      Compatibility with Web Browsers

      This Geoportal works with the following browser versions: Internet Explorer 8+; Firefox 3.5+; Chrome; Opera; Safari 3+. EPA MAPS (Envision) can be used with IE 8 but there are some small limitations in the display when these versions are used. These browser versions were selected by looking at what the highest web browser usage types are on Envision and the Geoportal before we upgraded this website. We got this usage information from our Google Analytics reports. While we regret that some users may be on older versions of these browsers and so experience some problems we suggest that upgrading or installing a second browser will enable you to use the Geoportal.
