If you want to create a map on the internet then you're faced with two choices: produce a static image (which isn't interactive) or set up a GIS web-server (which is expensive, even if you want to create only a basic map).
Scalable Vector Graphics (SVG) is a standard 2D graphics format designed specifically for the web and lends itself perfectly to mapping applications. SVG is based on XML and has a number of advantages over traditional 2D images such as gifs or jpegs (e.g. you can zoom in without loss of detail or quality). Given the complexity of most maps manually creating an SVG file is unfeasible. What is needed is a way to automatically convert your geospatial data into SVG and provide the functionality required to interact with the data.
This is where EasySVGTM comes in. It takes the hard work out of creating SVG files and provides everything you need to publish colourful, exciting and informative maps. You get the best of both worlds: maps with the functionality of a GIS but the ease of use and minimal cost of simple images. All you need is ArcGISTM and a standard web-server (as with normal html pages).
