First, yes, I know of multiple developers besides myself who are developing raster and vector quilting code. Have you seen our NOAA charts in our X beta? How about MaxSea Time Zero's unbelievable handling of raster and vector data?
The raster vs vector debate has gone on for a long time. Both are important and I'm not convinced that raster is going away for a while. I'd even expect to see vector charts rasterized for viewing in the future.
Raster vs vector is the very common computer tradeoff between time and space. While vector data is certainly smaller, it takes longer to display it. Raster data is much larger but is very quick to display if the data is organized in a way to display it (something that iNavX isn't optimized for right now since it appears to go back to the KAP data often which is line based). If memory size is an issue then vector data is better. But it's 2010 and memory is cheap and easy to get. I'd rather have speed over memory savings in today's world. Instant zoom and pan is more important in my opinion than saving a gigabyte or so of memory.
I was talking about quilting rasters on an iPhone (please remember, this is the iNavX forum) as were you in your original post. I don't think there is a benefit, nor do I think we will see it happen on the platform as it exists now. Quilting rasters on a COMPUTER is pretty well established and not really a big deal anymore.
I would be happy to test your iPhone navigation app that quilts rasters (or anyone else's for that matter...)) when you release it. Got an ETA?
