We’re well on our way with a good portion of this. We’ll have the “receiving” side of this done in the next couple of months. We’re looking at ways to work with different AIS networks as we speak.
Agreed Brad. We're hoping to circle back to the low-hanging AIS fruit soon. Will advise...
We are in active licensing discussions with CHS. Fingers crossed this happens sooner, rather than later.
As of this moment, our only source are CHS raster charts. We're in negotiations with them, but because of our proposed pricing model, its having to go all the way up the proverbial flag-pole. We're doing whatever we can to expedite.
This general idea keeps coming up so we’re thinking about ways we might include uploaded maps as another layer. Our principle challenge is that we currently tile all of the NOAA ENC’s into a singular chart layer (at all published zoom levels). So, incorporating imported charts would either have to be integrated into our process (somehow) or we would just allow them to appear as individual chart tiles – which might be a weird experience. If we’re supplying all of the same charts, we’re curious as to what the big payoff would be here?
The primary issue here, in part, is that data density. The entire U.S. chart set (at all zoom levels) is huge (40 some odd GB's of data). Given our "cloud" architecture, we've been working on a) data compression and b) the download process. We make a fundamental assumption that boaters do not require the entire U.S. chart set on their mobile devices all the time and that the preference is for the latest data in general regions - in real-time. That all said, we are still looking at being able to save data to an SD card as a means to save storage space on the devices themselves. To be continued...
Folks, our situation with this request is that we have fairly sophisticated algorithms that stitch all of the individual chart together as a seamless national quilt. In our system, you can search for a certain region (state, city, harbor or, for that matter, marker) and the system takes you right to that point. It would be very difficult to retrofit the system to “extract” individual charts. What would be helpful is to hear from you as to whether this is a make or break, or just something you’re used to doing?
Ok, we recognize that there is an incumbent method to updating charts et al. Its important to note however that the notion of discretely updating charts goes away with our system. Each week, we pull down the entire raster chart set from NOAA's servers and render them in real time. As you scroll around your regions of interest (while online) we are serving the absolute latest chart data. From there, you simply draw a region with your finger to download the relevant "charts" if you know that you're going to be off-line during your voyage.
We are hoping to license Canadian charts by the end of the summer / fall of 2011.
We're still working on it. The CHS puts some pretty sever encryption restrictions on locally accessed charts so we're having to contend with that. We believe its doable - perhaps from the server side of things - but its not trivial and caught us a little by surprise quite frankly. We know we need to get Canada on line and up and running but we're loathe to commit to another date - just to disappoint.
Loading charts via an SD card or removable media is something that we could implement (via Android, not iOS) once we have the right security technology in place – which is non-trivial. What we are focusing on right now is increasing the download region size per download so its a less onerous process. We’ll keep optimizing that process and see if that doesn’t resolve the problem at large.
A good idea. We’ll spin this around for a bit and see what we can do.
We just launched multi-point routing for iOS. Make sure you download the latest EarthNC Marine Chart updates and let us know what you think!
For the time being, you can readily drop a waypoint by selecting the Flag icon on the main screen on both the iPhone and Android apps. We’re looking into how we can enable a MOB button that is larger and more prominent – without screwing up the overall UI. Will advise…:)
