Use Scalable Vector Graphics (SVG) As Interactive Maps – MapsAlive

Scalable Vector Graphics, or SVG, is a format for images that can be zoomed or resized without losing any quality. MapsAlive lets you use either an SVG image or a bitmap image like JPG for your map. Which format is best for you depends on the nature of the map, its size, and whether or not you want it to be zoomable. Note that SVG is supported by PC and Mac browsers. You must still supply a JPG image for use on mobile browsers. In order to use an SVG image with MapsAlive, it must first have been saved as a SWF (Flash) file. Popular illustration programs like let you save your drawings so that you can open them in Adobe Illustrator format and then export them from there as SWF files. Once you have your map in a SWF file, you can simply upload it to MapsAlive the same way you would a JPG file. SVG works best when the map has a lot of fine lines or text, is very large, and you want to be able to zoom in and out to see more or less detail. When zooming out, fine lines and text in a JPG tend to get 'the jaggies' (parts of the lines or text drop out or show a stair step effect). The same map in SVG always looks its best at any size. To determine which format to use, try both and see which works best. SVG might not be a good choice if your map has a tremendous amount of detail and the SWF file size is very large. Why? Because your browser has to draw every graphic and text element when the map loads and while zooming. If your SVG map loads and zooms too slowly, consider removing some detail from the original illustration to simplify the image. to compare how the same map looks when you zoom it as SVG versus JPG. Both images look clear and sharp when you zoom in (click the to see what the JPG image looks like without MapZoom. Why does it look better? Because JPG images scale down very nicely to a fixed size, but not as well when they are zoomable. Once you have made your map zoomable, you can set additional options to change the location of the map inset, set the map inset size, and specify whether to show the zoom and pan controls. To change these options click and adjust the zoom and pan settings with the controls in the upper left of the map. Then click the lock icon below the map (the one that says 'Lock the current zoom and pan settings' when you mouse over it). Your settings are saved. Source.
