Webmapping is one of the first major real world SVG applications. Many Cartography/GIS specialists are looking into SVG for web-enabling their applications. However, developing cross browser and cross platform mapping solutions can still be a challenge. The SVG-only map navigation tools available at http://www.carto.net/papers/svg/navigationTools/ want to contribute to make this task easier, at least in the field of map navigation. An example is available at http://www.carto.net/papers/svg/navigationTools/index.svg
These map navigation tools had been tested in multiple browsers (Firefox, Internet Explorer, Safari, Konqueror, Opera), platforms (Linux, MacOSX and Windows) and SVG viewers (ASV3, ASV6, Batik). The features include:
- zoom in and zoom out with buttons and fixed steps
- continuous zooming with zoom slider
- button to go back to full view
- button for re-defining map center in main map
- manual zooming with dragging a rectangle in the main map
- manual panning with mouse-down and dragging in the main map
- linked reference map shows current map extent and allows repositioning
- coordinate display
- display of map extent (width and height)
