A question about soundness of principle as much as method, as I am very new to the subject.
Having to serve over web the polygons in way too large a shapefile (200Mb), I am wondering: could I, with some tool, convert all the data in the shapefile into a single transparent image (png I suppose, covering about 20,000km2) to then use as an easy to load overlay in google maps ?
Edit: I seem to understand Geoserver and Mapserver would create and serve selected, appropriate tiles of the resulting image on demand. Not lastly because we don't have a server to run Geoserver at hand, and since the data is static, I was thinking more of an actual image file. Does it make sense ?
